Throttle Position Sensor oil residue

There is oil residue on top of the TPS. I would assume that there is enough oil gunk/residue behind the butterfly plate that it creeped past the gasket. Should I have to clean it all over, there is only so much one can access behind the butterfly plate to clean the gunk.

Any suggestions will help.

How will a oil catch can installation mitigate the problem.?

The PCV is desgined to route any oil from the escaping from pistons to combution chamber to be burnt. Are you telling me the oil is not getting burnt in the combustion chamber?

I don't see any alarming levels of oil loss either. Would a heavier oil reduce the blowby..

the oil residue come from the pcv valve wich is routed back into the intake and then burned off, a faulty pcv valve may be the issue, i got to empty my can atleast 2 times a month

I'm going to cover old territory again. The oil in the intake that you see upstream of the TB is normal and is coming from the crankcase vent backflowing crankcase vapors (breather). This will occur during periods of low vacuum (large throttle openings) because the volume of these breather vapors (caused essentially by blowby) is above what the PCV hose/valve can handle. This is why the crankcase vent hose is sometimes called the "blowby" hose.

Well you can take the hose from the front valve cover and pull it off of the intake and put a filter on it. On the back vavle cover you can plug up that PVC valve and then plug up the hose on the intake.

When you go to smog, just make sure you put everything back. This will eliminate any blowby from going back into the intake. This blowby causes carbon buildup on your valves and the tops of your pistons. I have been doing this to my car. i put 145k on it and the valves look clean. I have looked at stock setups and there seems to be carbon buildup on the valves and pistons.

What exactly was the code?

Will your extended warranty cover it? Who knows, have you asked them? They'd know better than we would...

Well, you didn't answer my second question. Have you called the warranty company?

Yes, that's a TPS code. Your choices are most likely wiring or replacing the TB, as the DBW components inside the throttle body aren't serviceable.
