What work did you do on the engine, and what work was done by a machine shop?

(I rebuilt a 20R decades ago,   Machine shop did crank/rod work and basic block work (surface, hone).   I did everything else)

At this point, I'm leaning towards having Jim at 22RE Performance build me a 22RE long block.  When I started the rebuild I didn't think it would be that difficult to rebuild one, especially considering the reputation of the sources and services I used, and my automechanic skills.

From my experience, there is a lot of planning, knowledge, skills, machining, and careful parts selection that goes into the entire process of SUCCESSFULLY rebuilding one of engines that will go 200K to 300K miles.

Well, until you find out what was is actually wrong it is impossible to say who or what is at fault.  If could be bad set of new seals, bad rigs, poor machine work, etc., If you are lucky and it is seals or rings, no need in having someone rebuild it, as there is no enough wear yet to warrant it, just fix the issue and go.

Hey S,

Yep… I am anxious find out what happened and why.  As far as "no need to rebuild it", the engine will most likely need to be pulled and disassembled.  I want a pro to totally inspect the entire engine to get the results.

Just my thoughts…

I could remove the head and check it. I’d be very surprised if the valves are the issue without having any visible smoke. 

At that point I could mic the cylinders (bore gauge) and possibly measure piston to cylinder wall, piston-head clearance.  I don’t know how I could determine if the rings are the issue without pulling the pistons, without pulling the engine, means I believe I’d have to drop the front axle to drop the pan to remove the rod cap.

If I pull and disassemble the engine, and I do it myself, I would completely rebuild it with every part inspected and new parts used if necessary, and I would buy new pistons and rings from a recommended top manufacturer. I would have the block checked for all measurements and determine if it had to be bored or honed, and verify correct crosshatching and RA .

I’d probably buy a new rocker rack and install and brand new camshaft.

In other words, I’d rebuild, or have it rebuilt it correctly so it would go 250k or 300k miles.

Pull the engine out. It doesn't take that long to do and everything is so easy once out and on an engine stand.  :twocents:

UPDATE 1-11-2019

22RE rebuild – 150,748 miles.

I adjusted the valve lash and changed spark plugs.  There were several exhaust valves a little tight.  I adjusted the lash to the 261C cam spec 7 and 9. 

I replaced the copper plugs with about 25,000 miles on them - they looked really good - with a set of NGK BPR5EYs that only had about 50 miles on them.  Truck ran great.  Rocker noise was balanced and sounded normal.  After a quick test drive - tach’d it up to 5K a couple times – I parked the truck for about 5 hours. Went out to move it and it had a misfire!!  WTF-O!!  :yikes: :disturbed:  :headshake:

I pulled the plugs.  All looked good. I pulled each plug wire to see if I determine which cylinder was not happy.  Number 1 cylinder was not happy.  It was getting good spark.  Is it a fuel/injector issue?  Is it something to do with valves? No check engine light.  I am bummed and getting so discouraged with this engine rebuild.  :sad2:

I don't think I've done anything lately to pi$$ off the Toyota Gods?  :dunno:

I will pull the rocker cover and re-check the valve lash.

I have a bad feeling about this head from engnbldr, and I know it is not normal to have the exhaust valves go tight in 3K or 4K miles.  :dunno:  I'm also not sure that Mama ECU likes this 261C cam?

Suggestions or comments will be appreciated.  :beerchug:

UPDATE 1-14-2019

Did a compression check after re-checking valve lash. Valve lash is OK.

Compression test:  #1 33 lbs.,  #2 65 lbs., #3 155 lbs, #4 150 lbs.  I guess that explains the misfire.. not enough compression.

I will do a leak down test this week end to if I can determine if its valves or pistons.

I'll park it and probably wait to save up some money to buy a long block from 22RE Performance.   :gap:

If its the valves, I could have the head rebuilt, but I'd still be having the oil consumption issue that its had since I rebuilt it about 16,000 miles ago.  :dunno:

Looks like I will be pulling the engine again.  :disturbed:

I'm definitely NOT and engine builder.  :outtahere:

Did You adjust and check the valves by the book or on the back side of each lobe?

Yes I tried it and checked it both ways

I think You did something wrong. back off all the rockers to out of spec loose. Then reperform the comp test. See what You get then.
I find it hard to believe that two cyl. have dropped compression after a test drive. Logic tells Me Gnarly touched something and caused a problem. Again.....

Hey bgen.... as always I appreciate your input.

Geezz... I wish you were right on.  But I have a gut feeling that there is definitely some mechanical failure either in the head, valves, or pistons.  If a head gasket failed I should be able to see some indications.

I understand the reason to do a compression test with the rockers loose and no chance for a cam lobe to open a valve.  I'm pretty sure I'm going to see the exact same results.  Number 1 cylinder has been low from the beginning of my rebuild - just not THAT low.

I will see if I have time to do a leak down test this coming week end.
