656 oil pressure

You've got a point.

When I was a pup, I was taught that an engine really only needed 8psi to lube, so he probably has plenty of life left.

Although, I do think that with those kinds of pressures, the evidence of wear is certainly there. Don't they normally run up around 50 to 70 lbs?

That's for sure. The darned things seem to run forever.

This is what the local Red Shop told me:

The weakest point on a 656 is the crankshaft and it's bearings because the 656's oil pump can pump so much volume that problems can oftentimes go unnoticed until it is too late.

He says that the rods and mains ought to be checked as a matter of course every 5 years. He says to check the bottoms of the mains and the tops of the rod bearings because this is where the greatest load occurs. But, bear in mind that all the while he was talking to me about a diesel engine, tho.

Your pressures seem awfully low and since your's is a gasser, maybe you might want to think about the upper end too? Somebody told me that 5000 hours on a gasser was about at the outside limit.

I think it is a darned good thing you hooked up the gauge; you probably caught a problem before it developed into a major headache.

Dunno,
