Thread: 3.4 knock

Ran motor till warm to check temp issue. With bent pushrod knocking away. Dang. Stuff happens. VC are off now and there is plenty of oil on top of heads so I have some oil pressure. Put it together and check oil pressure? Or swap out lifters first?

I'd definitely swap the pushrods etc out. If you shatter something, then that engine's toast for sure! Sucks though. I know how much of a pita 3.4s are to tear down.
