I cracked my Valve Cover while changing my VCG. What Now?

I finally got round to doing my big VCG + Vanos Seals + Spark plugs + Winter tyres job.

Everything went well right up to the point where I reinstalled the Valve Cover. I made the mistake of tightening one bolt all the way before I'd fitted all the others. The pressure difference between the boltholes caused the VC to crack right thru the hole nearest the C5 intake.

I was gently cranking it with my torque wrench waiting for the pop and instead I get this CRACK and saw a tiny hairline fracture appear next to the bolt I was torquing. It was very unnerving, let me tell you.

The crack itself is very thin and extends maybe an inch in towards the center of the cover. I put a very small amount of Red RTV on the inside of the cover in the hope that it would temporarily seal it to allow me to come up with a more permanent fix.

Interestingly, I drove the car for a few blocks and everything seems to work OK. I was expecting to see some CELs or error codes (do these display on the dash or do I need a special widget to read them?), but the car started and drove beautifully.

Is there anything I can do to fix it? I'd imagine it's a case of buying a whole new valve cover. Anyone know how much they go for? Maybe I'll wait a while and see if any of the sensors notice there's a leak in the valve cover...

Anyone else have this problem? I'd love to hear what you did about it
