My Ride: 2002 vert m3 lsb smg

Like about a liter every 200 miles. That stuff is expensive and you don't look cool when your ride stinks of burning oil and has smoke coming up around the hood.

So, did I just get a bad cap, or is there some other malfunction that might force oil out around the cap gasket? I'm stumped.

I had the same issue with my new aluminum oil cap, all I did was take it off, put it back on slowly and looked at it at eye level while doing so - - and twisted it slowly till it was tight, then took it off and did it again and carefully/slowly at eye level tightened it till firm. no more oil leak. Even when I got my car back from an oil change, same thing happened - - I did the above and no more oil leak. Slapping it on and twisting it won't work with these aftermarket caps, you have to be precise.
