Guy you know how if you have no PCV system and there will be smoke / steam coming from your oil filler neck when engine is warm? Well its coming from the corner of my oil valley pan right by the oil filler neck too. What gives? Anyone else get this happening and should I order a new aluminium pan? This one is the original but the engine has be completely professionally rebuilt. I have been tunning the hell out of two different carbs trying to get a small exhaust backfire out and I think this may be the culprit. Thoughts?
