Not trying to be a dick, but you remember the bet they made that you would destroy your engine before the new year? You need to read and seach before modding anything. A small mistake can cost you a LOT of money in this game. Capping off the crankcase breather vents on the cam covers is a no no, and has been covered several times since the crash.
Like I said, I'm not trying to be an ass, but seach and read or ask before you do ANYTHING. Even though it seems like it may be a good idea, you have to have a good solid knowledge of the inner workings of an engine to make qualified descisions on things to do to one.
