I'm not too familiar when it comes to getting at the engine, so I'm hoping some of you can help me track down an engine leak.
2001 A4 2.8 30v automatic/tip quattro.
on the under side of the car it's dirty from oil dripping down and getting flung back by road wind on to the trany fluid pan in front of it and all over this one sensor/plug.
up towards head gasket seal area, i noticed a couple drips forming but i still can't see exactly where they are coming from. when i look from above in the engine bay, i just can't see anything that tells me it's leaking from there. when i look from underneath, it's grimey as hell all over.
the order of the pics are as follows. sorry about the cel cam but it's all i have. it should be detailed enough to show where i'm looking.
1. top of engine bay with coolant reservoir shown.
2. zoomed in to detail
3. same spot as #2 but from below the car.
what are things that could be leaking around this area? is there a way to tell if the head gasket seal is leaking?
*** i did have 1 or both of the cam tensioner seals (one on each side) replaced when i had my TB done a while ago but i don't think that's in this area of the engine?
any help is appreciated on any ways to tell where it's coming from.
