I had a leaky oil sump that was annoying me on the cossie and I personally thought my oil pressure was lower than it should be so decided to tackle both jobs while off for the Christmas holidays.
The below pictures are of a burton power oil pump that has done just over 9k miles from new, it was fitted at the same time of a full engine rebuild. Oil has been changed 7 times in the period and always used Millers cfs oil.
Got the lid skimmed as it was scored aswell...
You can see excess scoring on all the internals of the pump, the pump body is badly scored as is the cylinder and rotor. It's asif nothing has been machined to size properly or some shit has got in there. Also the hex for the oil pump drive is badly worn that it allows a couple of mm of rotation each way before it actually spins the pump.
Just posted these to see what you'd think, now fitted a new pinto 2wd pump and new oil pump drive but haven't finished assembling the car yet to see what psi I'm getting.
Cheers
