hi ive finally got my a4 on the road and all i can smell is burning oil , when i open the bonnet its smoking from the manifold area to the rear , theres a wire thats bolted to a bracket that goes to the starter motor , the housing where the bolt goes through was clean as i gunked it last week not it has fresh oil on it , what can be around that area dripping or should i say running down? its not the rocker gasket thats dry , it must be behind the heatsheild around the top of the manifold,
i dont want to drive this until its sorted or it might catch fire with the way its running down , its left a bigish pool of fresh oil on my drive already any help would be great , its a 1.8T AVJ 2002 model with 162k on the clock.:aargh4:

just a quick update , the rocker or half moon isnt leaking its bome dry , its either the silver thing at the back of the engine like the shape of a egr valve , or the turbo oil feed pipe , there both wet , on the turbo oil feed its where the silver solid pipe joins the flexi pipe behind the head.
also on the other side of the head on dipstick side under the rear of the inlet theres a 3 port breather hose thats split does anyone know a part number for this part please?

anyone? , ive pretty sure its the turbo oil feed pipe at the rear of the engine , they must be a welded bracket on the pipe at the rear
i started stripping the breathers out and there all bloody blocked , this cars going from bad to worse.

You could get the engine steam cleaned then start it and observe where the oil is coming from. If it's leaving a puddle on your drive you'll quickly see where the oil is leaking from it's very difficult to diagnose things like this without being there

If it was the turbo feed line i would suspect you would be having more of a gusher. Remove the aluminum heat shield that covers the line if it's the problem it will be obvious.

You mentioned that the breathers were blocked so you could be experiencing some higher than normal pressure in the crankcase which combined with an old VC gasket could be causing the leak(s) as well.

If its not the turbo supply line. I agree with the other poster. Try to clean things up a bit to really isolate the leak at the source. Replacing the VC gasket is a 1/2 hr repair and will cost you 30$. While you have the VC off clean it up including all of the breather passages.
