I considered this for a while but gave up because of the somewaht PITA to source it all plus it's not exactly cheap IMO.

I've never personally had issue with leaking cover because it warped, rather it was always gasket. I've heard they warp but never in my case.

I do hate CCV location under the IM and I've actually sourced correct size rubber hoses (engine oil compatible) and relocated the CCV next to 12V jumper location on driver side.

It looks factory (IMO) and now I can change / inspect CCV in matter of minutes vs hours.
