The Air filter was completely saturated in oil so its not something i can overlook as i doubt the car can breath properly.
Il have a look at the "tube of death". should spray test the seal with aero start?
im at about 198xxx on the odo so its pretty high mileage.

check the seals on the "tube of death" under the intake manifold
an oil film may me normal, but puddles is not.
for some odd reason, a big vac leak from that tube will cause oil to pool up in the intake.Leave a comment:

That isn't abnormal on a higher mileage M20 engine. Wear of the rings or cylinders increases blow by and thus the flow of oil vapor into the intake. Other than make a mess that doesn't really hurt anything until the blow get's really bad and the car starts producing a smoke screen.
A leak down test tells more about the condition of the engine than a compression test.Leave a comment:

I'l add that i had a compression test done last year and came back fine.Leave a comment:
