    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 ****, 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.

    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.
