I would definetly pull the head at this point. A little word of advice somtimes the heads take a lot of muscle to free em from the headgasket (block). I had to use my cherry picker to pull my brothers head off (that sounds funny) it wouldnt budge otherwise. Lil pressure and a plastic hammer and it came off.
Pull the oil pan as well (you'll want to anyways to get the front cover back on properly). Will give you a good look at the crank, bearings, pistons etc.

You would pull the head? Are you sure?.........

Lol....yeah, the head is definitely coming off. The chain definitely skipped. And I'm positive one or more valves are bent. If you heard the way it sounds when you crank it....along with the other symptoms....you'd go,"Yep...that's messed up." The thing nagging me at this point is not knowing about the bearing cap/s, yet. I truly hope nothing is screwed beyond repair.
BTW, that raises a question. It occurred to me if the cam and journals need machining, that will make the cam smaller. Would this not affect the amount the power the motor would then produce....considering a larger "racing" cam (with larger valves, etc.) produces more?
Thanks for the tip on the head. It's never been off in 220k miles, so it probably will be quite stuck. If it comes to extreme measures, though, the vehicle's park 50 ft. from a shop where they have all kinds of goodies. It
will come off! Rarrrgh!
The oil pan? Hmmmm.....maybe, maybe not. Since I'm pulling head, there won't be a problem securing the timing cover. The only thing about the pan is I'm still considering replacing the cylinder rings and the pan would have to come off to do so. Undecided. Reason? The front diff., of course, has to come down. That, mi amigo, will be quite a project. Not afraid of doing it. It will boil down to time and money. Compression before this breakdown was very good which should indicate the rings being in adequate shape. Although, there are alot of miles on them. Enggh....I'll think about it more after I get down that far. For now, all I want to think about is making chocolate chip brownies.
Thanks for the input, Drew.
Hasta luego!
