Well that rules out fuel pressure.

Hi H8PVMNT,

Yes... I'm glad because I didn't want to have to buy a new fuel pressure regulator, and R&R the chamber.  I doubt the new fuel filter could be so plugged it is causing a problem.

I'm at the point where I'm trying decide to just reinstall the stock cam that came out of head.  Or... buy a new camshaft.  If I buy a new cam, I'm debating between the one I had originally picked based on owner's feedback and Engine Analyzer's data -CompCam 252S.  It still shows the best numbers for my 2500 to 3500 RPM range.   BUT..... since I have done some mock pulls on the Schneider cams.... one of them looks VERY interesting and could be a good choice for me.

Here's the Excel sheet that I posted before, but I've added the Schneider cams.

What do you think?

For me it would be a toss between the 252S and the Schneider 244-50 (tug boat bottom end).  The bottom Schneider is kind of interesting too but it seems kind of contrary to what you are aiming for since it looks more peaky.

I think the 252S is your best bet though...

I think if you chose either cam you would significantly increase the number of dollars you've spent on the motor which is where the upgrade will be most noticeable. at least with a thinner wallet,  your butt dyno will be lower in the seat and you might be able to feel a difference.
in all seriousness, you should take all future funds you plan on spending and save for a dual overhead cam 2rz/3rz and never look back. i feel like I am pleading with a gambling addict who thinks if he keeps spending more he will win :)

Then again, it was a 22R-E and an old 22R that were in Moab if that has any bearing on this discussion about which engine is the best...

Maybe when Gnarls has his 2nd or 3rd midlife crisis he will springs for a V6 Camaro or Mustang and then get some bolt-on upgrades for performance...

2 months in, still not running right, this is what you should do, not buying another cam.

The stock cam will remove any "cam cause" from your running issues, and allow you to focus on other possible causes if your running issues remain.  You will also have a "stock" cam w/rebuild/other mods seat of the pants experience to compare with the other cams.

I love my 22r and I don't want a 3RZ in my 4Runner anymore, but I will concede you will never, ever get the power, drivability and economy of the 3RZ with a 22RE, even on a pimp's budget.

I still have that extra carb manifold for you though :).

As I move through this rebuild project, I am concerned about my out of pocket costs in money.  I grossly under estimated the cost and time of the project.

I am not happy with the outcome and disappointed that the number of real and potential failures is so unexpected… it’s my inexperience and insufficient pre-start research.

I hope to get it running right without too much more financial investment.  Although I’m well north of $5,000, so a few hundred here and there to get it running the way I think it should doesn’t seem so significant now.

Regarding engine swaps, at this point, I would only consider swapping in a Toyota 22R, no other Toyota engine.  As I said, I will keep an open mind.

If I do an engine swap it would be Chevy 4.3L Vortec or I might build a 215ci aluminum block, like the old 1963 Buicks… but to get a referee pass and passed any emissions testing could be problem.

By the way, I’m not a gambler, but I am somewhat eccentric and probably addicted to my quest to make this rebuild successful.

I agree, but I was only really after a few more lbs of torque and a couple more HPs for passing.

As I said, if I wanted a reasonably low cost investment, serious power, with high reliability, availability of parts, fuel economy, and me being able to work on it... I'd swap in a Chevy 4.3 L Vortec V-6.

Yeah.... that's the direction I'm leaning heavily in right now. 

I don't what the 261C to be the problem, but I should have gone with my gut feeling..... CompCam 252S.

I'm not sure which midlife crisis I'm in, but I can tell you that I would NOT have a 6 cylinder in a Camaro or Mustang!!!

Gnarls, I'm just giving you a hard time. I appreciate your willingness to share your frustrations with us. I think most of us have gone through this in one way or the other we're just not so brave to let the wolves gnaw on us. I also ended up putting the stock cam back in my 22re build and it did solve some of the rough running issues I was experiencing. I feel we have a lot in common as I'm considered an eccentric(and a smart ass)  by most who know me. I like to keep an eye on this thread, it's like someone is ghost writing my 22re build story.

Gnarls,

Just to recap where you are at with this, you are happy with off-idle performance, is that correct? The main problems are bad cold starts, a high idle that does not work, and then idling too high after it is warmed up?

Did you ever block off the EGR? If that leaks slightly you'll have all sorts of idle problems. Adjust TPS? Get timing back to stock? Get number 1 and 8 valves adjusted correctly?

Another couple hundred miles on mine and I am very happy. I seem to be getting more power. The 261 may not have the idle power band for you but it seems unlikely that it is the cause of your problems.

I do agree with a post a while back that the 261 likes a little higher idle. I have mine set around 900. At 750 it is a bit rough and does a little of the random blub-blub thing, like it wants to miss but not quite that bad.

Arnt you running engnbldr's rv head? when I was considering going that route Tod told me that I couldnt run a stock cam with the RV head ( I wanted to know if going back to stock was an option if I didnt like the aftermarket cam). I dont know why it wouldnt work but if your planning to give it a try you might ask him about it first.

The symptoms andykrow just mentioned, if thats what your experiencing it sounds like classic IAC valve symptoms. I think you have already been through that but thats what it sound like to me.

Good luck, and keep after it  :thumbs:

Yeah... I have had more than expected issues.

Flat-spotted tires
Fuel pump failure
Front input shaft seal on tranny was leaking, but may have stopped leaking right now.
Injector pigtail connector on #1 injector had to be replaced.
Had to buy fuel pressure gauge to test the fuel pressure regulator.
Won't cold start like it should
Noise in rocker cover.. that has me concerned!
Could be running a lean AF mixture, I don't know if its the cam and it's overlap.
The idle RPM would change after driving it, went up by 150 to 200 RPMs.
The low RPM blubber at slack throttle is abnormal, but I can live with that.. again it may be the overlap in cam.

I still need to test the EGR, readjust the valve lash before I swap the cam, and readjust the TPS, pull the plugs again to check color, and get some more miles on it before doing another compression check.

It's now got a loud squeal when I cold start it!!!!!!  I think its a v-belt (the belts are tight, but I will recheck), and sounds like a pulley, alternator, or A/C pump pulley is not spinning at start up??? It goes away after about 2 or 3 seconds after it fires.

Yes, it does seem to have nice lower RPM pull.

I can live with a 900 RPM idle.

My time and attention to my truck has been pushed back a little due to a some health issues in my 69 year old body!!

Sucks to get old!!

Well.. that's interesting, you put the stock cam back in!

The wolves don't bother me, they usually make me laugh or give me some good advice.  I like the banter, it adds lots a fun to the sometimes boring technoid-talk, and smart-arse comments always rev up the dialog and brings out the bugs in forum walls.

Yes, engbldr's RV head, with OS valves with 261C cam.

OK, I'll check with Tod on this cam.  bestgen said he thinks my idle/start up issues is the Air Valve.

classic IAC valve symptoms.
Yup. Isn't the test to close the idle screw all the way in once the engine is warmed up? If it doesn't die then the IAC is leaking air through when it shouldn't. I hear an air bubble can sit there in the coolant and and cause trouble although I have not experienced that myself.

Hey Mudder,

Can I assume that you have checked out other possible causes for your engine to "fall flat on its face" at around 4500 and 5000 RPMs?  Or.. are you convinced its the 261C cam?

Have you talked to Tod or Ted at engbldr?

How many miles on your rebuild?

Are you planning to change the cam?

Thanks,

Gnarls.

Gnarls, my last 22re came from my old truck, an 89 22re with an auto tranny so it was in amazing shape. I won't be swapping cams as I'm moving away from the 22re for now. My 84 is getting a 3rz swap (thank you H8!) with a turbo or supercharger and my regular I'll go back into my 89.

This "loud squeal" that dies out after 2-3 seconds isn't so abnormal in my experience. When I was driving a '93 22RE with 100k on it, it would squeal on start-up if the temp was below 25F or so.

Not saying it's not something to fix, just that it may not be a fixing emergency.

Hey emsvitil...

I need to confirm what I think it is at Ace Hardware.  I'm about 97% sure it's 8mm x 1.0mm.... but I don't want to give you the wrong thread size.

The other threads are standard 1/8 NPT.

I'll stop by Ace this afternoon after work and verify it.

Sorry for the delay.

Since the 261C and RV head is a big part of this thread I'll keep updating here.

Anyway I decided it was time to do some high speed pass climbing this weekend, so we put 500 miles on it on the way to a wedding in BV. I am very happy with the performance so far. This build compares favorably to other 22re's I have had especially considering the tire size and rig height. I was able to pull the 3rd gear hills easily at 4-4.5k rpms. These are the type of hills that a weak 22re will require 2nd gear with. A couple of times i missed the power band and was at 2800 or so, and was still able to accelerate, albeit slowly. And then at the higher rpms I was happy to see that I really did not need to be on the gas pedal hard at all.

The next hill test will be east bound i70, vail pass and eisenhower tunnel. If I can get those at 3rd gear I will be very impressed. Even stronger 22re's typically need 2nd gear on them. I probably won't be on those until fall, so that test will be a ways out.

Other notes - idle was noticeably lower at 8.5k feet. About 750 rpm instead of 900. Around 850 - 900 is where I like to sit with this cam, it gets a little rough under that. Back in Foco the idle was right back where I have it set.

I do still finding myself think a little more off idle torque would be nice. Maybe I will try the 252 in there in a couple of years. But I also need to drive another 22re truck every once in a while to reacquaint myself with how they take off from a standstill.

Finally, best part, with 500 miles of hilly highway, keeping her around 65-70 mph, I pulled 23 mpgs over the whole trip! :clap2: Strangely, I have always found that out here in CO my 22re's get better mileage with hilly highway driving compared to flat land.

I have similar experiences even with a carb 22r.  I almost always get my best fuel economy pulling 4th of July and Lookout Pass when I head to the coast and back.

Hey andykrow,

Great information.. thank you for the feedback.

I’m happy to read that your rebuilt is performing well.  I would guess that some people would say that at 500 miles on a rebuilt 22RE is still a little tight. I find it very interesting to read the differences in outcomes from the engine rebuilds. I’ve been compiling information for years trying to come up with some kind of trend or common results, but I’m not sure I have any conclusive facts.

The lower RPM at 8500 feet is a little puzzling, but I assume it’s the richer mixture.  Getting 23 MPG at that elevation AND hill climbing is awesome!  My 1st 1986, I bought in 1986, one time got 28 MPG, but I was really trying to see how good I could get on a tankful… on the flat, no wind, cool weather, no AC on, 60 to 65 MPH, light on the gas pedal.

What octane, formula, and whose brand of fuel are you burning?

Off idle torque… well that is what the 261C is supposed to do.

Sorry about the lack of updates here.  In my last 2 years of physical exams the Drs say I’m in excellent health for my age, so when I suffered a ruptured disc between L4 and L5 about 5 weeks ago, causing Sciatica from my right butt cheek down to my toes, it has put the brakes on me crawling all over my truck.  Treatment is ongoing, so I hope to be able to continue with solving the issues I have with my rebuild.  Of course right now my garage is 100 degrees.  Doing my obligatory early morning outside chores 3 times a week kicks my old arse!
 
Back to tech….I am curious about your compression at 500 miles and what the spark plugs look like. Also, when you adjusted your valve lash, did do it as described in the FSM or with rocker sitting on bottom of the base circle?

Congratulations on a job well done!

The 22s were built to "work"... they like to be exercised.

Ah what I meant by 500 miles was the that was how long the trip was, and that was the distance I measured the mileage over. I am about to hit 2000 total miles on the rebuild. No change in valve noise, still quiet. Still chasing a slight exhaust leak (or it's the DT just being noisy?) but I'm about to permanently solve it by turning up the radio.

As for gas, I just use the cheapest, lowest octane I can find. Typically King Soopers ("City Market" where you are?) because of the fuel points. Up at this altitude we get 85 octane so that is what I use. I'll put 87 in at lower altitudes of course.

I have not had a chance to do a compression test and I don't really have any plans to buy a tester, so it will probably be a while before I get a chance to do that. I can say that with about 1700 miles on my current oil, the level has not moved in the slightest on the dipstick. So my rings seem to be seated. Definitely no oil leaks. (first time ever, haha) Great power so my guess is compression is fine.

I have not adjusted valves yet, but I do plan on doing that in the next couple of weeks. I will stick to engnbldr's 007/009 spec, and I will definitely use the base circle technique.

Now.. the off-idle torque... I think I really need to sit down in another truck and compare. In general these 22re's are weak and I will find myself annoyed at them from time to time. So apparently depending on my mood this will feel like it's making great power or it will feel weak as $hit. This truck does require very little gas to get moving so that is a good sign. I do really feel it come on after 2500, and that is really nice for the highway driving as I've said several times. If I traded the highway power for more off-idle power that would NOT be acceptable - the only time the off-idle bothers me is driving around town. So if there is a compromise to be had I am happy where I am at.

I do think the low idle is a rich mixture issue. At first I thought it was happening after driving highway for 4 hours in 90 degree weather, that has happened in a couple other 22re trucks. Drive it all day and it idles low. BUT, in this case, the next morning, as soon as the high warm-up idle went away the idle was low again. Then as soon as I got back into low altitude the idle was normal.

I am definitely surprised and pleased by that mileage. I was not trying to baby it and there were head winds for a lot of the drive so I think I can get better. The best I could get out of the old engine was 19 mpg. The best I ever saw was from my first Toyota - a 1980 4x4, with a hybrid 20/22, weber 32/36, DT open exhaust. 31's, 4 speed and 4.10s, got 28 mpg on a 3000 mile road trip that included a fair amount of wheeling. I wish I could say I tuned it (then I would have some info for H8PVMNT) but alas I bought it from someone who was apparently a master of that setup.

Hey andykrow,

OK, sorry I misread your post on mileage.  Geezz… I wish I had 2000 miles on my rebuild.

Exhaust leak… The DT header will sound different and sounds like a tinny ping, I like the sound.  I’ve read that you can tape a vacuum cleaner hose to the end of the tailpipe and listen for air sounds??

I’d really like to know what your compression is, but I understand dolling out money for tools. I have spent a bunch this time around for this project.  It sounds like you’ve got it broken in perfectly.

When you adjust the valves, would you mind looking at the rockers, and where they sit on the valve stem and where the rocker pad sits on the cam lobes.  Are any riding off the cam lobe?  Please take a few photos and post.

Your performance seems to be very good for 22RE and your average elevation.  With a carb’d 22, it is estimated you will lose about 4 lbs. of torque for every 1,000 feet rise from sea level.  With 22RE with MomaECU and her little sensors, it’s my opinion that you won’t lose quite that much.

My rebuild…I am not happy yet with the power at 50 MPH and up. It seems sluggish after pressing the gas pedal to the floor, even in 3rd and 4th gears.  It will pull hard after 3,000 RPMs in 1st and 2nd.  But… I may be expecting too much over the engine before I rebuilt it.

Your MPG looks good for the driving you’ve done.  I’d bet you would get into the mid to upper 20’s at lower elevations and 87 octane, for average driving conditions.  Engine tweaked and peaked TUNE is critical for getting top performance out of these engines!

Thanks for posting up your experiences so far… awesome feedback.  :beerchug:

Yeah I am having trouble differentiating if that ting sound is from the head or a slight leak. I did swap over to the remflex (again) and the gasket I had in there showed a leak right by one of the egr inlets, on the header flange side. So it is possible that there is a little manufacturing flaw on the flange. Maybe someday I will get that trued up. But I only really hear the sound in first and second gear and it is easily drowned out by the radio. After that the mud tires take over  :shake: Those combined with no carpet inside (just bedliner) and a there ends up being lot of noise coming into my cab. I need a better radio!

There does seem to be slightly less noise with the remflex although I could be imagining things. And I do feel like I have heard that sound out of other headers DT included so hopefully that is all.

I was honestly shocked at the mileage I got, especially considering 35's. No doubt part of it is sticking to 65-70 mph. This truck kind of forces me to stay there though. It will drive even smoother at higher speeds than that, but I don't trust it's ability to do an evasive maneuver when I'm doing 80+. And the lady starts to get nervous, haha.

Sounds like you should get behind the wheel of another truck with a 22re if you can! That always grounds me. Other non-22re vehicles tend to have more pep than my truck, and often I'll get back into my truck and just be like "ugh this is slow" haha.

I will certainly snap some picks of my rockers once I open her up. I may be able to get to that next week although I have a busy few weeks coming up here.

My performance does seem to be better than most of the 22re's I have had in the past. I have a couple benchmark hills around here and it seems to do the best so far. I can maintain fifth on the entire Foco to Denver interstate run which has some decent hills that previously required 4th.

Of course it is difficult to compare to previous trucks since I have never had a new rebuild with this exact setup. My last 4runner 22re had about 30k miles since rebuild, with 252, DT and open exhaust but no oversized valves. This truck does marginally better than that one, although that truck was on 33s and 4.10. The 4runner before that one was on 33s and 4.88, unknown miles on motor but good compression, TG header and open exhaust. This truck destroys that one on the climbs :)
