Thanks in advance for any thought/comments before we start tearing the top of the engine down. And does anyone know if the 2.5L is an 'interference' engine?



I did a search and couldn't find a definitive answer on this question. I believe it is though. I have seen comments saying it is, others saying it isn't.
