Hello, so im having a problem with my 2001 4.7 V8 dodge durango. I was driving car got hot lost power yeah yeah whatever. So i tested it, cylinder 8 misfire long story short the the valve seat fell out of vavle hole supee weird. So i fixed the problem rebuilt the heads did everything i was sopoussed to do. Now when im putting everything back together im having bad compression checks?!! These stupid timing chains are a nightmare, im doing exactly what it says in the book step by step word for word and i cant seem to get it right. And ive already replaced a couple brand new vavles because they keeps bending I'm sure it's because the stupit timing chains arnt right. So if theres anyone out there that can help me with my problem that would be sweet! Im right there i know im i can do this just need a lil help.

Thanks you hope the here back from whoever is reading this

 

I don't know anything about the 4.7, but if you're bending valves it definitely sounds like your out of time.
