Moonie - It defo dosn't stick when its just the crank in there. I'm thinking oil pump now aswell mate.

When we fitted it, we tried to make sure that the flat edge of the block was inline with the oil pumps, so they were both flat togther. The idea being that it'd make a better seal for the sump gasket

B13nde - All the bores were oiled up! Come on i know its my first time but i aint that daft

I was wondering if it was something to do with not priming the oil pump up yet, as i was going to do this once everything was built up before we tried to start it
