Re: [T3] A question about oil pumps


You are very lucky that you didn't break the camshaft
gear off the camshaft when you tighened the pump up, I
like to dry fit my pumps before installing them,
during the buildup of the engine with the flywheel and
camshaft laying in the case half, I fit the oil pump
to it to make sure everything clears, yes I have had
to adjust a few oil pumps to clear. Phil
