I have a 2002 Golf 5 speed, and I'm doing some maintenance on it.
Among other things, I'm replacing the clutch because it was grabbing very badly, and I'm also replacing the seal on the vacuum pump as it was leaking oil.
I just got the clutch off, and now I realize that these two problems are probably related, and now I am concerned.
When I got the transmission off, there was a puddle of oil in the bottom of it, presumably from the vacuum pump leak. The oil leaks out of the pump, runs down the back of the head and block, and is able to seep between the engine and the transmission to contaminate the clutch.
I cleaned up the transmission, and I am going to get the flywheel resurfaced tomorrow. Now, I'm assuming that this is the reason my clutch went bad so early... it is only about 40k miles old... a South Bend stage 2 clutch kit.
Obviously I don't want this to happen again

and it seems like sometimes the leak is not from the gasket that seals vacuum pump to the head, but rather from the gasket that seals the two halves of the vacuum pump together. I replaced the former. I cannot tell form looking at the vacuum pump where the leak was from.
Has anyone else had experience with leaky vacuum pumps and how did you remedy it? I don't want to ruin another clutch with oil contamination.
Here's the options I believe that I have
#1: replace seal between vacuum pump and head (DONE) and hope for the best
#2: replace the seal between the 2 pump halves using a BRM oil filter o-ring as noted in the above thread
#3: RTV both sides of the metal plate between the engine and transmission to try to avert any oil that should leak down there
#4: RTV the seals on the vacuum pump to try to help with sealing
Any opinions or insight is appreciated, thank you.
