I don’t believe a one-tooth slip will cause piston-valve collision. I think I’ve seen posts where it was stated that it has to be off maybe 3 teeth or more for that - I could be wrong. And it may be different number of teeth depending on pitch differences of 2.7 chain and 3.2/3.5 belt.

Oh it's interference all right, just look at what happens to them if the timing chain tensioner slacks off....

dodgerunner If it is not listed by looking up the model then you can check on this pdf list. For an example if you look the 95 3.5 if you look after the V6 there is an *. Means it is and interference engine.

DrDodge yes the 2.7 is a interferance engine,, so is the 3.2 and 3.5 but ive never seen a 93-97 3.5 crash valves and ive seen quite a few busted belts on them

Daytrepper 1st and 2nd gen 3.2s and 3.5s are all interference, as well as the 2.7. The only one that wasnt interference was the 1st gen 3.3.

The FIRST gen 3.5 is non-interference IIRC <-- Someone verify this for us!

ALL second gen motors are interference. If the blelt or chain breaks on your 2nd gen, you have a NICE, FAT EXCUSE to port and polish the heads

The 3.3 I'm not sure on, something tells me it is also interference... I'm fairly sure the one on my dad's 2001 Caravan is at least.

no matter where the valves are in their cycle.
Perfect laymans terms!
