I have a 1967 Garrett 15-b log skidder powered by a ford industrial 172 ci gas engine. I believe this engine is internally identical to the ones used in early ford tractors. It was rebuilt a few years ago it recently showed copper shavings in the engine oil and filter. Oil pressure dropped from 40# at idle to 10#. engine never missed a lick. I pulled engine and rod and main bearings are fine. Distributor and oil pump seem tight. I hate to keep tearing things apart for no reason. Anyone have any Idea where my copper deposits are coming from?

Replacement of engine: Have #200 Timberjack skidder built in early 60's with Ford 172ci gas industrial engine. Engine shot. Located Ford 201ci diesel out of late 60's Ford 4000 farm tractor. I'm I craze for thinking about pulling 172 gas engine and replacing it with 201 diesel engine, with little more Hp & better fuel economy.
How would engines match up at bell housing?
Some Ford 4000 tractors early had 172 and later had 201 engine.

The 172 ci Ford engine has no cam bearings.

The only things I can think of that would throw copper through the system are wrist pin bushings or bearing inserts. ??? ray

worn cam bearing could cause both copper and lost of oil pressure

Cam brgs and wrist pin bushings could be cause, but don't forget to closely inspect the thrust faces on your main brgs. If machine has a manual clutch, the forces exerted when releasing the clutch force the crankshaft forward, over time wearing out thethrust face on the thrust bearing. If unit is a torque converter/powershift type, these forces are greatly reduced, but still present to some degree. Check thrust surfaces before pulling pistons or cam. Past experience.
