Okay so I'm having an issue. One day I was driving my 93 Toyota with a 22re and it died instantly. I towed it home and went through fuel and spark testing and all checked out fine. I then pulled the valve cover and placed it to 0 degrees TDC on compression stroke. Now I'm staring at it and I can't tell if it jumped a tooth or teeth or not...anyone have pictures on how it's supposed to look when it's at TDC? My bright link is on the little notch which is right before 12 o'clock and the lower bigger dimple on the cam gear is right at 12. Also I had taken my distributor out without marking it and want to make sure I am putting it back in correctly...how exactly do I do that? Which direction do I place the spark side of the rotor before putting it back in? I started tearing apart the timing chain and am down to the crank pulley and have a funny feeling that the timing isn't even off. Idk I'm sorry but can someone please help me?

When the dot on the cam gear is @ 12:00, the dimple on the crank gear should be at 6:00 on the crank. The keys on the crank snout should be @ 12:00.

The shiny links on the chain are only useful on first assembly of the timing components because when the engine is turned over, the chain link position travels, so that the links only come back to their original positions every once in a while. They are'nt likely to help you now.
A lotta people talk about these chains jumping, but I don't believe that it is possible for it to really happen.

My timing sprocket was missing 2 teeth when i pulled mine apart. I can't believe mine didn't jump.

There was also rub damage inside the cover where the chain was hitting the cover.

It is possible for it to jump.

However i will back the bright link thing as useless.

And back you on the dot on the sprocket at tdc and the crank piney mark pointing to 0 .

On the 22re the cam mark will be slightly off but not a whole tooth

I like to use these two videos. Once you have the timing chain and sprockets set, basically you set the rotor to the 11 oclock position and it will rotate to the 12 oclock position.

A Timing Video I like Better. Set Crankshaft pulley to 5 degrees.

Easy way to install distributor on Youtube.

I'd like to hear about any firsthand knowledge you have pertaining to timing chain jumping on 22r type engines.

I just told you. My timing sprocket on the crank had two broken teeth on it. And damage to the part of the cover next to the crank sprocket from the chain binding and hitting it. If teeth can break off , then the chain can jump time. Combine that with a broken guide and bad tensioner then it is possible.

Well DUH

Anything is possible when there is major mechanical failure.

But you say that even with missing teeth, yours did'nt jump time.

I'm talking about the timing jumping where the engine can continue to run, or be repaired without replacement of all the timing components.

I doubt it would run. However the op stated his does not.

However i think it is unlikely his chain skipped teeth i just answered his question about it jumping.

Getting off topic slightly.

Back on topic. I think tearing it all down to check the timing may be over kill at this point.

How did you check for fuel and spark. And is the spark a nice white or blue or is it orange. Orange spark aint worth a damn.

A compression test would be worth while i think

terry, i think that's backwards. when the distributor is inserted, the rotor turns counter-clockwise. so set it at noon, push in, and it rotates back to eleven.

Correct
