Replaced valve cover gaskets but I think still leaking from camshaft tensioner.make damn sure valve cover gasket mating surfaces are clean as a whistle before installing them especially where "v" shaped part of gasket sits.rtv sealent is a must have for that spot.

It is a consistent problem after replacement of a new valve cover gasket. I have replaced it two times.

I have a leaking valve cover and a broken crankcase pipe (which runs off the back of the valve cover and along the side of the engine to the oil filter assembly) on a 2005 A4 1.8T? I'm also having the timing belt changed (63000 miles).
Oil leaks from valve cover gasket and camseals are important to take care off. If the timing belt gets contaminated it will result in serious repair costs and possible major engine damage if the belt breaks.
