Not to interupt the conversation and "advice" with additional correct information, sometimes known as facts, but the engine in his car is 100% non-interference. No matter if it's a 3.0 or a 3.8 (a tiny bit of information that is always helpful), the valves WILL NOT contact the pistons unless you lose a valve keeper or the locks.
On these engines the valve springs go into coil bind about .100" before making contact with the piston. I can tell you from personal experience that a 3.8 with the heads shaved .060" still has plenty of room left between the valve and piston at TDC and coil bind. The same would hold true for the 3.0 as they're essentially the same. Unless the engine has been seriously modified, or put together with the wrong parts, the valve to piston contact theory is garbage.
On the other hand, every 3.0 or 3.8 I've seen with bent pushrods, and I've seen lots, has been caused by the engine being over revved. Fortunately they're a fairly stout engine and it normally causes no major damage. However, after an over rev and with bent pushrods I have seen them with collapsed (mechanically jammed) lifters, which could cause a no start.
All that being said, why are we wasting time with guessing? Has a compression check been accomplished yet, and if not, why not? Why hasn't it been recommended in this thread? Why do people keep yapping about things they don't know anything about?
The last question is rhetorical. Have a nice day.
Thanks for the pic, jedimario.
