[QUOTE="thatsmokinobs, post: 1193478, member: 18875"] ok we are in kinda a bad situation right now. my parents and i were on our way to D.C. to help my sister move back home to PA, and dads 6.4 may have killed it self. about 6 months ago or so, i was driving it and noticed it was ticking lightly from the passenger side valve cover and kind of bucking at idle like it was missing. so dad took it to a garage and they couldnt find anything other than 2 "bad" injectors, but $1300 later, that didnt do a thing for it. then i took it to UNOH's open house and halfway there, the bucking stopped but th ticking got louder. it ran fine, no loss of power, no excessive smoke, nothing other than the ticking. about around christmas, we took it to get a couch and i noticed it was blowing a lot of white smoke, which it never did before or since, i dont know if it was a regen cycle or not but i didnt think it was good. we shut it off and turned it back on and it stopped. until today its ran just the same and as strong as ever. 3 hours away from home, dad noticed a thumping sound from under the hood. we pulled over and its blowing through the intake, like a valve is stuck and there is a lot of white smoke coming from the oil cap. we turned around and drove an hour and as soon as we pulled into a rest stop parking lot, it started knocking. we think it threw a rod. has anyone had this happen or know of someone who it did happen to? is it time for a new engine? or time for a 7.3? neither of us have a clue how to work on these fancy new fangled diesels but i guess we are gonna learn.
