schlackoff, you have had too many hard drugs too long.

Sounds like a cracked crankcase. Can come from a connecting rod
parting company with piston or crank. Invariably expensive.

I have never seen a case like that where the engine continued to run. Why
do
you think that is the case?

Most of the time I've see that happen, the engine does continue to run
on the cylinders it has left operating. At least until it doesn't have
any more oil. I've seen engines continue to run (very poorly) in
everything from a 2 cyl lawnmower where the broken rod punched a nickle
sized hole in the crankcase to drag racers, where it happens frequently.

I have. I have seen a rod break near the wrist pin, punch through the
crankcase then snap clean off the crank (bolts sheared off). Other than
having a big hole in the crankcase the remaining cylinders were just fine.

Horrible mechanical sounds and oil everywhere are the common symptoms of
having a rod punch through the block.

A burnt/seized piston could cause a lot of blow by which could force oil out
of the case, causing the oil mess but I wouldn't expect it to have the
horrible noises associated with it.

A rod knock would sure be noisy but wouldn't have the oil mess.


My guess is along the same lines as Brian's: it threw a rod, punched a hole
in the crankcase. What's left of the rod is still banging around inside the
crankcase.

That engine is toast.
