Thread: Oil leak F1 td4

Just thought I would thank this thread because replacing the PCV filter fixed ALL the other oil leaks, including front main seal.

I have taken a few pics along the way with the replacement. Have to learn how to post them in here.

The job took only 20 minutes once I got the air filter cover off. Even after vacuuming around the cover there was still some dirt and stuff that dropped into the engine but there was a plate underneath the cover that catches it and allows you to clean it off with a rag. I was nervous disconnecting the fuel lines - be careful because the spring clips fly far. Suggest use needle pliers and grab and pull - don't flick.

I couldn't believe the price - bl00dy LR dealer, $76 for a bit of foam over a plastic cage no bigger than a golf ball, an O ring and two shaped slot gaskets.

Suggest wear surgical gloves because it is a messy job. I will replace it again in 100K

Clearly the intercooler will need cleaning-out or replacing; might explain the drop in performance and fuel economy. Anyone tried doing an intercooler on the Td4?

Cheers, Demi

I changed mine for the new style which does away with the filter - went down to the local BMW dealer, a bit of parts searching and we had the new one in town the following day. It took all of 20 minutes to fit.
