D2 5u motor locked?

Sounds like you might have a broken connecting rod. Pull oil drain plug to see if any metal comes out, save oil in a 5 gal bucket. It could be so many different things, start with the least costliest item and go thru a mechanical check list. Good luck!!

mate I would just pull the head off and have a looksee even if it is rusty in side you might be able to save it by gently jacking down on the cylinder heaps of diesel first fill each pot up and leave for a few days if rusty before trying

Yep! pull the head, then youll be able to check the liners for any scoring or pitting, might as well check the valves and guides and reseal the prechambers. This way you know everything is checked and no problems down the road with head etc.

FYI , took valve cover off,,, all valves move,sucked the mouse nest out with shop vac and dumped a mix of pb blaster and evapo rust into the cyl that had the exhaust valve opened and dumped some in the other exhaust ports in the manifold, now we wait and see

I have had mouse nest inside cylinder having entered through valve. I was able to clear it with shop vac set to blow through intake and working closed valve up and down manually. Nest material exited through exhaust.

Tried turning motor with a pipe wrench with a 4ft pipe on the end today and still stuck
