Warm engine smokes from exhaust /fan operation

Disclaimer..I'm not a tech but reading the threds and descriptions I don't think head gasket as well.
How's the performance? Just perhaps, if you can, try a compression test. Takes about half an hour and you might have a cylinder with a marked difference in compression. If you do have a marked difference, then perhaps a leak-down test on that cylinder might tell you whether the rings or a valve is allowing oil into the combustion cylinder. I saw a video on leak down test and one supposed could tell if air is coming out the next doors spark plug hole, you might have a compromised head gasket.
Those are the things I would do on my car if I had the same issue..
A compression tester I bought from a local jobber store,decent quality, for about $50.00 and I bought a Snap-on leak down for about $90.00. I understand there are stores down there that will rent out some of these tools saving plenty if only need to use once or twice. The evolution itself is easy.

Hey So Cal Mark,
would you like to elaborate.New at this and can use the help anand your expertise.

a leaking head gasket will allow coolant into the cylinder, not oil (other than a really rare, bizarre incident). So if you've got oil smoke, oil is either getting into the cylinder down the valve stem or by the piston rings
