I have an 01 jetta tdi and i have a decent amount of oil coming out of the egr valve and coving my valve cover. What could be causing it? blowby?
I recently dismantled a failed EGR valve from my 2003 Golf. Not an easy thing to do, btw, as it's not designed to come apart. Had to grind the cap off.I have an 01 jetta tdi and i have a decent amount of oil coming out of the egr valve and coving my valve cover. What could be causing it? blowby?
If you plug those holes on a working EGR valve then the EGR valve will quickly get stuck open - i.e EGR on all the time - as the space under the diaphragm becomes pressurized and the EGR piston is permanently raised.no I have had the same issue ever since I disabled my egr... it weeps out of the hole, I was considering plugging these holes. I was told not to plug the hole if I had an operational EGR, but an idea was thread a plug in, and route your leaking oil somewhere else? catch can? a little one but who knows... idea.
I am assuming since the holes are for a WORKING egr, that if ones egr is not in operation, we could plug it?
Other wise, clean it everytime you fill up!

thanks for the info everyone! i'm considering doing what bluesmoker suggested as there are no emissions tests in our area. i assume this will cause the check engine light to come on. my friend has the vag-com software is there a way to fix the light with that? this is prob a dumb question but why is there oil in the egr in the first place?
Except they can get bad enough to be a little bit of a fire hazard. I just bit the bullet and replaced mine. $120 for a new one a member never installed. I apparently caused it as it only leaked after I used degreasers on it while cleaning it.Bottom line. It's only a cosmetic problem, not a functional problem, so you can safely ignore it.
Well, I hadn't really thought about the fire hazard angle. Good point.Except they can get bad enough to be a little bit of a fire hazard.

There's no way to know really. If only someone who had taken one apart had taken the time to explain exactly where the oil comes from at 4:34pm on 10-9. Oh well.this is prob a dumb question but why is there oil in the egr in the first place?
So, I am confused. I thought when the valve is in the closed position/no vacuum, that the EGR is off.If your EGR valve is non-operational because you have disconnected the vacuum hose or for some other reason, but the EGR valve diaphragm is intact, then plugging the holes will again cause EGR to be on all the time.
Yes, that's correct. No vacuum means EGR valve closed, hence exhaust gas recirculation is off. That does not stop pressurized charge air flowing through a worn EGR valve piston bushing however, bringing oil with it.So, I am confused. I thought when the valve is in the closed position/no vacuum, that the EGR is off.
Yes, afraid so. This shuts off exhaust gas recirculation but does nothing to stop the air/oil leakage through the EGR valve piston/bushing.I have had the same oily situation and a broken ASV arm, so I decided to unhook both actuators and vacuum lines. I assumed that this would act as a "Race Pipe" and fix the oil problem. Obviously, I am mistaken.
You said, "The oil is coming from your intake". I was asking how does the oil get into the intake.There's no way to know really. If only someone who had taken one apart had taken the time to explain exactly where the oil comes from at 4:34pm on 10-9. Oh well.
