When you say your car was smoking earlier in the thread, it looks to be because your breather catch tank (which you have now replaced with a mocal ) wasnt actaully allowing the engine to breathe. Was suposed to have one inlet and a vent to atmosphere on the old breather but it seems you used both ponts for engine only, with zero ventage to atmosphere.

Old - No Ventage


New - Ventage through screw on cap
