I've noticed that there is a humming sucking sound coming from the engine after I go for a drive. It is coming from the oil cap. When I remove the cap, the noise goes away, and the idle speeds up some. If I put the cap close to the opening, it is pulled towards the opening. Has this happened to anyone else? I just replaced my oil cap a couple of months ago.
