91-95 Non-Interference

 

96-97 Interference

 

But, I have heard of both (91-95) hitting the heads and (96-97) not hitting the the heads.

That is what I had thought. And that is the problem...mixed statements of valvetrain contact in either. CRAP!

 

Why can't it be SIMPLE! You damned LQ1 lovers! :wink: :lol:

 

I have a line on a possible cheap 3.4 car and if it is non-interferance I should do pretty good on the return.

 

Alright..thanks guys :cool:

best question to ask about it is when the timing belt broke, say they tell you "well i was passing someone on the highway" and that means they were prolly in a higher rpm range so greater change of damage. or "i was sitting at a redlight" and that would indicate probably no damage.
