i am so stuck.

i have a 86 22re turbo motor in my 85 pickup. my pickup had a stock 22re with snaped rod. reason for the new motor.

when i bought the 22re turbo it had a tick sounds like a valve so i figured i would put my stock head on and have a turbo motor.

PROBLEM:the new head still ticks

when i took the head off the turbo motor the 4th clyd. intake valve was stuck down and the pistons and valves were caked with crap.( lots of it too)

i have check timing and replaced rockers,check lash,watched for stuck valve.

i dont know what else to do plz help me.

the friend i bought it from just rebuilt turbo but said it may be tick as that someone told him that? possible? i donno?

bottom end??

it has a hesitation too.

Can we move this to tech??!?!?!?!?!?!?!?!

Hello midnightoys,

I bought my '87 4Runner about 4 years ago. It had a ticking noise then and I just recently discovered what the ultimate cause was. After replacing the timing chain, rebuilding the head, and adjusting the valves countless times. I replaced the bearing on the idler pulley for adjusting the belt tension on the power steering pump. $8 at Kragen. Fixed the problem. I wish I had done that first ... I also made it worse one time by putting the valve cover on wrong and the intake valve adjusters were tapping against the side.

Good luck, and keep at it.

The valves are loud on these, but i would aslo check the timing chain to see if it is rubbing the guides. it could be an exhaust leak too.

no the heads are the same except you have to move 2 exhaust studs and the head is alittle thicker. iasked all around and its fine. the tick is loud and coming from 3rd or 4th cyld. sounds like top end but i donno trying to figure out. its not the exhaust either.

There is a head volume difference, but not enough to cause problems putting a 22re head on a 22rte...

Any idea on what part of the motor the knock is from?

You are correct about increasing compression, but you can't determine how much compression it's going to add without knowing the particulars of the 22RTE piston design.

The 22RTE compression is between 7.5-7.8:1... Many people have successfully swapped in a 22RE head due to a failure of the 22RTE head.. Yes, it increases compression, but not enough to cause issues.. On a truck that's basically limited to about 8psi and has very low starting compression, a slight increase in compression is fine.


Try that long screwdriver trick I told you about to see if you can isolate what part of the motor the knock is coming from...

Timing chain tensioner. It is alway the problem when you have a tick that sounds like a diesel. It is the chain flopping around. It is worse just off idle.

Takes alot of gut to admit that on here.

I'd say it was a gamble also - but if you spend any time over on the 22RTE yahoo group, you'll find more than a few people that have done it with great success.

If you begin to run the calculations, you'll find that the remaing volume on the 22rte is a lot larger (just per the pistons) on the 22RTE than the 22RE... It's not just a combustion chamber deal, it has to do with how much air those pistons are shoving up...


On the knock - can you record it or isolate it somehow? More info would help.. Lots of things can knock.

I see your in snohomish, I could possibly have a look at it.
