no offence wayne but its you that's missing the point lol. the engine is actually a 1.8 pb mk2 with a smaller pump than the agg engine. so my question is. would the larger pump off the agg engine increase the oil pressure of the pb engine? everthing else been equal. the thing is if I fit the pump and then find the pressure is a bit excessive then I can go down a grade on the oil. like from 10/40 to 5/30.
