... and in the outlet of the AFM? I just intalled a new air filter and noticed that there is a bit of residue. What causes this?

Oil in the intake boot?

Oil in the intake is pretty much normal for an engine with significant miles on it. It is there partly as a result of wear of the rings, and the resultant increase in blow-by, and partly from worn valve guides & seals.The car makes it possible, but the driver makes it happen.

They do have positive crank case ventilation but not a valve. Inside of the valve cover there is a baffle, if it gets crudded up it can lead to excess oil in the intake, so can unchecked inlet of air (seals etc.) however there will always be some.
at any rate I recommend fitting the M20 with an oil separator in the vent system this can greatly improve the performance longevity of the engine and other components.

No PCV in a m20. The crank case vents into the intake. You get a bit of oil in the intake boot and what not. Its not that big of a deal wipe it out and move on. If you find a quart or lots of oil all the time then you have some issues that need to be looked into.Originally posted by FusionIf a car is the epitome of freedom, than an electric car is house arrest with your wife titty fucking your next door neighbor.

what if the said "oil in the boot" is probably the cause of a failing TPS?
I cleaned my TPS out the other day which seemed to alleviate my erratic idle/CEL/etc temporarily. But the motor is acting up again, and I feel it is due to more oil getting in there, but I can't be sure.Claus Luthe is my hero.
