2003 Audi A6 Quattro Question: Oil leak
1 year ago I had an oil leak ("from the top of the engine"). They changed the manifold gasket and it was ok. Recently, after an oil change, my engine is again leaking oil (with a bad smell). What other gaskets may need replacement? My local mechanic says the oil is coming from the top of the engine. Thank you, Enrique - Visitor
If the oil is coming from the top of the engine then you most likely have a leak in the seals around the valve covers. This is not a serious condition in VERY small amounts; otherwise you must replace the valve cover gasket. - M_Kast

I'm looking for an estimate on the cost of repairing an oil leak in the turbo's. I can't find that listed on the list you supply Can you help?
Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.
A fluid leak may develop from the propeller shaft seal on the rear of the transmission. Our technicians tell us that replacing the seal will commonly correct this concern.
An External oil leak may develop from the valley pan gasket (under the intake manifold) and/or the head gasket.
