So i'm assembling an SR and the headgasket appears to be for a g20/200sx non turbo SR20De. He got it from Enjuku, and i've heard about a thread on FA about this, but i don't have an account there. just seeing if it matters...theres no gasket around the rear oil drain and the front cover has a threaded hole that doesn't line up with the gasket. Apparently this engine was run before with this "cometic" metal gasket. Any ideas if its ok or not?!

 

Not OK. It'll leak oil pretty well at the rear oil drain.
