Low oil pressure after full engine rebuild.
I’ve rebuilt 1.4 mini one engine but I get low oil pressure flicker once car is at temperature. So today I finally got round to checking oil pressure and unfortunately it’s low, it starts around 2.75 bar but once I’m up to temperature it’s around the 0.5 bar so that’s why I’m getting the pressure warning light.
So I’m thinking it can only be pump, crank bearings, oil filter or a blockage? or I have done something wrong during rebuild?
I’m a bit gutted after all this work but I’m hopeful I can find the problem.
So for reference it has new crank bearings, new oil pump, new oil filter , new piston rings, new cylinder head gasket, new oil seals, new timing chain. Car now runs very well and get no engine management lights, just oil pressure warning light when car gets up to top temperature.
Any advice or thoughts would be appreciated. Thanks Donny
