I believe the answer is in your head... Sitting there in your garage or driveway.

So.... are saying that IF the engine had some valve "float" at my "drag race" 5,500 RPMs, the floating valve(s) would contact the top of the piston?  :smack:

Yes exactly.

This interesting because I believe the 261C cam profile has one of the higher overlap (6.2 degrees) of the cams I have recorded or tested.

QUESTION:  Could excessive camshaft overlap  (significantly greater than a stock cam profile) be more likely to cause valve float, and potentially cause valve to piston interference?

Yes absolutely. Changing the lift, overlap, and duration will 100% increase the potential for valve to piston contact. This is controlled by stiffer valve springs, multiple valve springs, larger valve relief and a designed rpm range for a specific cam profile.

UPDATE:  Feb 23, Saturday PM

Started at 1:30pm – stopped at 4:00pm

Got engine at TDC #1 cylinder firing.

Removed distributor & wires.
Drained radiator, pulled wires and hoses, removed chamber, removed fuel rail & injectors, removed intake manifold.

I would NOT do that again on a 22RE. :thumbdown:

I would drop the tranny and pull the engine. :thumbs:

Doing a head R&R on a 22R is WAY easier. :yesnod:

Tomorrow I need to remove the power steering bracket, two heater hoses, and drop the DT header,
remove the cam sprocket, remove the hidden bolt, unbolt the head bolts, remove the rocker rack,
then I should be able to get the head off.  :gap:

UPDATE:  FEB 24 Sunday PM

I got the head off.

I see some things.  I took some photos. - I REMOVED THE PHOTOS.

The photos did NOT come out as well as I wanted.  The vavle/chamber contact areas are shiny alloy looking, the photos don't show that reflection. 
EDIT:  THE SHINY AREAS ARE JUST WHERE THE CARBON WAS NOT STICKING TO THE SURFACES OF THE TOP OF THE PISTON, AND THE AREA AROUND THE VALVE POCKET.

#1 & #2 chamber - There is appears to be contact on the chamber where the exhaust valve opens and closes.
EDIT:  THIS TURNS OUT NOT TO BE THE CASE

Chambers #3 & #4 color looks different, as they had normal compression.

I cannot yet determine where the coolant leak is on chamber/cylinder #3

The hone marks on the cylinder walls do not appear to be at 45 degrees?

I need to do some editing and labeling then I'll post the photos. 
EDIT:  I REMOVED THE PHOTOS - NOT WHAT HAPPENED

Since I am not a head expert, I will take this head into someone I trust can examine it, and hopefully tell me why it failed.

I have a lot of questions.

Do a basic leak check on those valves using very light compressed air and brake clean/water (besgen trickle down).  Remember, ur looking for compression loss...

And what about head gasket?  Main sealing rings?   Is there a cylinder cleaner than the rest?

Two things
Valve float
And what fuel are you running (tons of carbon)
Wait wait I got it... Arco fuel? Saving money again Gnarly?

Two things.... LOL.... 1st - contact.... what caused it?  :dunno:

2nd thing...yes... there is carbon!!!  It was burning 1 quart of oil every 600 miles.  And.... NO... I don't burn Arco.  I burn whatever Fry's Market  pumps or Costco.... 87 octane.  Saving money, being frugal, is NOT a bad thing. If you are rebuilding a 22RE, buying less than quality parts to save money is not very savvy.... that's just my  experience.  :gap:

I hope to have someone look at the head and tell me what caused the failure.

As I stated from the first time I fired the engine at break-in, I suspected something wrong with the valves and the head.

I doubt that 5,500 RPMs in a 22RE would float a healthy valve train, even with the heavier 1mm larger stainless steel valves... but I'm no expert.

I'm very curious about the abnormal oil consumption.

UPDATE:  FEB 25 PM

I spoke to my local head shop today.  I am going to take a day off work to go there and have the owner, who has been rebuilding engine cylinder heads for over 20 years, inspect my head and show me and tell me what he determines has caused the failure.  He was also the one who rebuilt my head on my 1985 22R in 2002.

I am going to see him on Thursday morning.  I'm also taking in my original factory head to have him look at and possibly rebuild it as well.

I hope to have some answers to my list of questions about this head.

Buddy, years ago, did a head gasket on his 4runner 22re to solve a coolant leak issue, had oem head sent out.  He installed it and after very little time he was using coolant again.  Now, im not sure if he had known cracks before in it, but he chopped it in half with band saw and it revealed alot of erossion from electrolysis and showed how porous the head was inside the cast...

Hey E..

Yes... the factory head, at least in my 1985 22R head, did have erosion caused from electrolysis.  The head shop showed me where on the head the corrosion appears to cause a problem... it's the water port next to the #3 chamber that was cracked and corroded.  The head deck also had pockets of corrosion and eroded surface.  If I remember correctly it just over 200K miles on the engine when I did the head job with rebuilt head and new stock camshaft.  I did not replace the rocker rack at the head job.

UPDATE FEB 28 2019


I spent about 1 hour with the owners of Phoenix Cylinder Head Service, Import Specialists, John and Greg.  John has been building cylinder heads for over 35 years…. I trust his opinion and expertise.

John confirmed my gut feeling and suspicion that something was NOT right with the valves.

Here’s his inspection, measurements, testing, and results:

The engnbldr head included in the DNJ Rebuild Kit:

The head had no markings that would identify it as a DNJ head. 

The engnbldr 261C camshaft is a factory cam that has been reground, interestingly stamped “DNJ”

The exhaust valve springs were not symmetrical, warped or bent.

None of the 4 exhaust valves were sealing.

The exhaust valve faces were sitting into the seat so far that only the very outer edge of the valve face was contacting the seat… That explains why the exhaust valve lash was going tight!

Whoever assembled the head did not check the valve angles and the seats/valves were not ground properly to provide the critical valve to valve seat seal. 

The faces of the exhaust valves were pitted badly with carbon from being over heated.

Although there is no confirmed evidence of valve float, the #1 exhaust valve stem could have over heated and seized in the guide.  There is no visual evidence of valve to piston contact.

He looked and inspected my original factory head, but it was slightly warped (I overheated the engine in 2013), and would have to be decked requiring a shim or thicker head gasket and heat straightened.  So for the cost of rebuilding the factory head or rebuilding the engnbldr head would be more than if he buys a new bare head and installs his choice of springs, seals, guides, and valves.  He recommended a new head.

He only buys import heads from 2 sources, both Chinese.  He said DNJ heads he has purchased have been a quality product. – no issues.
 
Regarding the quality of a Toyota factory head (high quality aluminum alloy), he said he prefers to rebuild a Toyota factory head one over a Chinese head.

He also prefers and recommended a Fel-Pro head gasket for this head rebuild install.

All 4 intake valves were sealing.

My factory stock cam looks fine and the rockers and rack look fine, so John is going buy a new head, install new stock valves and springs, use my stock factory cam and rocker rack.

This new head may or may not solve the oil consumption problem.  I will see how the new head and stock Toyota cam performs, check gas mileage, and see how much torque I will feel at 3,000 RPMs.  I can always swap a camshaft later.

At this point, I'm disappointed that engnbldr is out of business and cannot address my findings.  I am very disappointed in the head they supplied.  Now that I've gone through this experience, I know what I would do differently and what I'd recommend to anyone rebuilding a 22RE. 

A time consuming and expensive learning experience.  :thumbs:

My engnbldr head that I bought years ago was made in South America according to what he told me. I had a problem with casting voids in the head causing a liquid leak into the exhaust chamber. The only thing the 261 cam did for me was allow more torque at a lower rpm.  I am going back to a stock cam with my new engine I will install this spring.

Hey P...

Yeah... John said that the factory head also had issues once in awhile with leaks inside the exhaust port.

My 85 22R with a factory rebuilt head, built by John back in 2001, and new 22R stock cam ran really strong. It averaged between 19 and 21 MPG on 89 octane fuel.  I had the DT header and opened exhaust, turbo muffler.

I am very curious what another cam profile will do.  I believe that a higher lift/duration cam profile will work really well in 22R.  I don't think that a higher lift/duration cam profile will work as well in a 22RE because the ECU and O2 sensor will work hard to balance the AFR changes the cam will do.... but I'd really like to find out.

You should consider starting a thread just about cam shafts for 22r and 22re?  :smack:

Hey bgen!  Well... IF my engine rebuild had come together like I was expecting it to, I would have had my truck on an engine dyno at least 3 times by now!! ... And I'm NOT kidding!

I wanted to "test" by swapping camshafts in my freshly rebuilt 22RE.

So... I don't know that I will get to do that?  I have some more work to do on getting my truck in the restored condition I hoped to.

On the cam thread... there's lots of information I posted already with lots of input from some guys like H8PVMNT. 

I'd have to find the thread.  [EDIT]  HERE'S A CAM THREAD:  https://board.marlincrawler.com/index.php?topic=100575.0


Of course.... it could all be worthless opinion.  :beerchug:

Dont use factory head, aluminum is very porous

This is a matter of opinion, according my local head shop, he prefers to rebuild a factory head if its rebuildable... says they are very high quality and disagrees with "Don't use factory head, aluminum is very porous."

Since I don't want to put the new head on and discover it's still burning oil, at this point I am thinking of pulling the engine, tear it down and starting over with the rebuild.

I'm not sure when I will do it.  :dunno:

I may have Jim at 22RE Performance build me a long block?  :dunno:
