I took it back and I was not very happy. They called to say that they found the leak and the valve cover was warped. There solution was a new valve cover or they would try a different sealant. Does anyone have any ideas on what causes a valve cover to warp, unless it is pried off and bent?
I guess I am going to do all my own service or get rid of both my BMW's and get a Goldwing.
Although I guess it can happen, I've never heard of the LT valve cover being warped. I would think maybe sloppy handling of the valve cover gasket, and/or re-use of the gasket without cleaning out the old sealant, to be more a prime suspect for an oil leak in that area. There isn't much oil that get's in that area, so any leak should be minimal in volume.
The valve cover gasket , at installation, gets RTV sealant at only 8 points on the gasket (at each side joint of the four half-moon humps) and a very thin coat applied to the area where the cylinder head, timing case cover and valve cover meet at the front portion of the block.
And in some instances, the front center valve cover screw, which is just ahead of the spark plug area, and somewhat hidden, has gone un-noticed during the final torque tightening, or missed altogether.
At any rate, just to let you know what the possibilities are that could lead to the oil leak (how bad wuz it, btw??); other than a 'warped' valve cover!!
And please tell me that the charge for valve *check* wuzn't 1,000 bones!!!
Other work wuz done, right?!!
