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?!
