350 TPI speed density setup.
All of a sudden my engine is very smokley on startup and seems to have oil coming out of tail pipe when i rev it cold
engine oil on air filter side of throttle body
pcv valve working correctly
once warm no smoke
I reecntly had a sticking ICV but now doesn't seem to be working at all (no idle up when cold anymore)
ANY thoughts would be great

 

Pull the valve covers.

Inspect oil seals on valves.

Now, it COULD be a failed piston ring letting combustion gas past the piston, and over-pressurizing the crankcase, and blowing oil into the intake.

But, Occam’s Razor and all,... I’d inspect the valve seals as a first suspect.
