My buddy has a 01 S with misfire codes on all 4 cylinders. I did a leak down test on it and #1 is 14% #2 is 38% #3 is 25% #4 is 8% do you think it has some bent valves in it. That is my thought I just wanted to get some opinions before I pull the head.

Thanks

Justin

 

Did your friend overrev the car?

 

He says he didn't but knowing him I think it's possible

 

Pardon the ignorance, but i guess his CEL came on?

 

Yes, your buddy bent his valves when your buddy over-revved his engine
