Hi, my r33 has been sat in my garage for a while, i started it up today and it was missing. Found out it was cylinder 2, took the spark plug out and it was wet with what looks like oil and it looks like there is oil in the hole on the piston. The car ran fine before the engine is fully forged, was done a year or so ago and has hardly done a thousand miles since. So what would cause this. Ive fitted a topmount manifold and turbo and fitted a front facing plenum. Any help would be great. Thanks.
