Hi,

Just completed a 2.5 conversion on my P1 using the original heads (which have been tested and skimmed) and a 2.5 gasket kit. Stuck it all back in and it starts and idles fine but theres an oil leak from the breather hoses that go on the manifold, also I removed throttle body and found the gasket covered in oil and will need replacing again? Any ideas what could be going on as I'm stuck! Thanks steve
