I'm starting to think the cam cover on my '11 Roadster must be warped, and I was wondering if anyone has had theirs successfully resurfaced by a machine shop (~$20), or if I should spring for a new one ($230)?
The cam cover gasket first started leaking a few months ago @4k miles, so I replaced it. I was very careful, followed Nev Lush's tips, and tightened the cover progressively using a torque wrench. Now with 10k miles, the gasket has again bulged from the same spot and started leaking. The first time was with the stock crankcase breather setup while the 2nd time is with a RamAir breather, so I'm pretty sure excessive crankcase pressure is not the culprit. I didn't check the cam cover gasket surface for trueness the last time I had it off, but I'm starting to think it must be slightly warped.
I saw a few other members (@08nzrocket, @mr hunt) have had similar problems. I'd be interested to know if a new cam cover solved the problem for good, or better yet, if I can just have the local machine shop run my original cover through a belt sander to straighten it out.
Here's where the gasket failed on both occasions:
