    PCV System

    I appreciate this has been done to death already ... but ....

    Ok, so for the past few weeks I've been stripping down the engine bay - refitting gaskets, shining some things up - but more importantly, going through the entire boost/vac system trying to find this damn leak once and for all.

    Anyway, I think I found the problem. I took off the crank case breather and the T-piece its connected to - basically its full of coked crap, gunk and the rubber is lame. There is a split in the 90 degree pipe coming from the suction jet pump thing (gaping hole - would never have found it unless I'd removed everything!). So I'm gathering part numbers etc for a phonecall to Audi this week. I have an idea it will cost me a small fortune to replace everything I want.

    So is there another way (tried and tested ?) of doing this PCV system with silicone hose and pipe fittings ? Surely it would be better in the long run - and replacing any further parts in future would be a hell of a lot easier. Has anyone ever done a DIY PCV ?

    I need some suggestions (or anywhere to buy cheaper-than-audi OEM parts !).

    Thanks in advance.

    Have a read through this thread mate:

    Oil Catch Can mini group buy anyone? including PCV system simplification.

    It'll probably work out cheaper if you bought a catch can and some 19mm oil grade hose then going to Audi for the full system. I've been very happy with my setup since ripping out the old crap. The only thing I want to change now is the ventilation to the TIP.

    Audi will rip you off out your arse. Just buy some silicone hoses mate, easier and cheaper.

    Thanks for the advice. I phoned local dealer today with 6 part numbers for small pipes around the suction jet pump ... came to almost 60. I think I'll do the catch can - never happy with that amount of oil going through the pipes.
