Managed to get hold of an agu engine last week,got it all fitted this weekend,had to change the sump from my apy engine so cleaned the pickup pipe while the sump was off,drove the car home and after about 20 minutes of driving the oil pressure warning came on,I stopped at a roundabout and it went off again but then after I came off the roundabout it came on again,got home and theres a rattly noise that sounds like its coming from the sump but not sure what it could be
