    What clearances should I be looking for when checking the oil pump? Anything else I should be looking for? Thanks.

    Using a feeler gauge check the clearance between the outer rotor and the housing. Should be between 28-32 thou

    You must be referring to the pump end play? You cant check the cover/gear clearance and theres no spec for that. You can use a straight edge and put pressure on one side of the pump, you should have between 1 to 3 thou change but usually if the pump has too much end play it shows up in the spec I posted and it wont pass that either.
