No

I would put it back together with new gaskets and use dishwasher soap with tap water (the stuff in the green box) clean the system good do not use Dawn it foams and watch it for awhile, a bad gasket could have been the problem if the full face gasket was bad that mates up to the filter base housing

I bought Permatex Aviation gasket compound #3, couldn't find #5...

Ok after all the work looking for a possible area where oil may be leaking into the coolant - I'm recently suspecting the engine air compressor... Engine oil and engine coolant cross paths in the cylinder head of the air compressor. The BW TU-FLO 501 air compressor is passing oil really bad into the discharge muffler and also into the wet tank. Is it possible that the compressor can be leaking oil into the coolant?? I'm trying to beat this one to the ground. Any thoughts?

The rings are wore out and need replacing anyway,, so no loss..>>>Dan

Check the ping tank. It has a drain. Any significant oil accumulation there points to compressor, unless it has been years since drained. If nothing comes out, make sure drain isnt plugged.Leave it drain over night. I would put a couple of hundred miles and recheck tank for amount of accumulation, then change comp . If necessary. That way you wont replace something that may be ok. Cliff or Luke will tell you which one you would need when replacing.

Coolant is just on the head of the compressor to help cool the discharged air,when the head cracks which is very rare you get coolant in the engine oil or excess pressure in the coolant ,when the head gasket blows they will fill with water and shear the drive or the key anything is possible but I never saw one that leaked oil in the coolant system
