Just went through my '88 22Re and replaced the head gasket and timing chain. Bought my timing kit from engnblder. Everything went real smooth and I'm happy with my work. I put the timing gear on the crank, keyway in the 12 o'clock position, timing dot in the 6 o'clock. on the camshaft, the cam pin was in the 12o'clock and the timing dot was just slightly to the passenger side. lined up the shiny chain links on the dots, put everything back together, stabbed the distributer and lined it's bolt up right back where it was.

Now, everything runs great, and the truck fired right up, but checking the timing the mark on the crank is about 2 inches advanced away from TDC. It would be about 45-50 degrees I'm guessing. If I move it to 5 degrees BTDC the engine just about dies. I shorted out the T and E1 terminals and that didn't do anything to cancel the timing advance. Did give me a 5-1 code for my oxygen sensor though. When I rev the engine from idle, the timing goes back to about 7 degrees advance. Is there another way to kill the advance and check the timing? Am I missing something here?

Also, do all 22re's almost shut down when you pull the oil dipstick? Or especially the large hose on the valve cover? (not PCV, the big front hose) always thought that was wierd.
 
I had a similar problem with my 20r the timing mark was quite a bit off.... It ran fine though. Come to find out it was in deed a tooth off. The tensioner has some slack to take up. I do not remember clockwise or counter but when I work on old worn out crap I have to be sure to turn the crank by hand a certain way or I can easily be a tooth off. It makes me wonder if you are as well. I am really guessing you are a tooth off at this point. Again mine started right up and ran fine but DID NOT line up with TDC or even close It was about 2" off if I remember right. It had what I thought was normal power for a 20r but got horrible fuel mileage
 
That was my first guess too. I'm a pretty experienced mechanic, so I hated to doubt myself on being a tooth off. It makes sense, except for how it returns to the correct setting when you rev the engine. Makes me wonder, because my TBI chevy engine acts the same way until you unplug the timing connector, then it runs rough, idle speed drops, and timing goes to the set point. I figured I would get a similar reaction when I jumped out the T and E1 ports on the Toyota, but that does absolutely nothing.

I lined up the chain with the long driver's side runner tight. All the marks were lined.

I also had the head re-surfaced and the vavles done, and unfortunately, I have a pretty bad erratic miss now. That really hurts my feelings. :mad:

I had a similar problem where jumping the T E1 ports didn't change anything. I could never get my timing to set correctly. For me it turned out to be my TPS was not adjusted correctly.

Here's a great TPS adjustment website:

Nah... dizzy is right. About 95% sure the chain is too. The way I see it, in reality, you don't even need the colored links as long as both your crank and cam keys are at 12 o'clock, you're on. I checked and rechecked the link placement. I'm sure its right. Thing I can't understand though is why the exhaust smells so bad now. Very sulfer smelling. Wondering if knocking the egr valve around messed it up. No time to check anything, stupid work...
 
Your engine will run like crap with the breather lines off due to the large vacuum leak created. With the lines connected the system is sealed. How far was your head shaved, this could be the timing issue, if too much is taken off the cam is now closer to the cylinder deck which could allow more slack in the timing chain. Perhaps you did not correctly short out all the terminals, depending on the MY you may have to jumper two sets of connections.

That fixed it! Turns out the TPS adjustment was way out. TPS was still good, just needed to be moved. I timed the engine by ear and feel before this and it turned out I was within 2 degrees. :hillbilly: Idles like a champ now, with no miss, smooth as glass. I can only figure the miss is gone because the timing came way down at idle.

I love my 'Mud community... Kris, you the man!
 
Hey no problem. I fought mine forever and was so glad when I found that page.
