ok so today i checked the oil cooler with the one fitted onto the old engine and its fitted the correct way.i started up the engine and took oil filler cap off and there is no oil splashing about at all. the head gasket was fitted the right way around, but would it be possible to fit wrong one ? the head set was for 2.0 16v abf, metal type gasket, could the gasket be wrong ? i dont really fancy taking the head off just to find out that its ok. i was planing to check oil pressure at the switch with a guage. what pressure should it be when idling ?
