oil pump different Options

[dmenche914]

Just inspected my oil pump, it is a Type I pump in my 914 Type IV motor. It is an after market cast iron pump 1.15 inch long gears, .004 inch clearance between ppump cover surface and gear tops (without gasket) and a .004 inch gasket for total .008 clearance between gear tops and iron cover (body is also iron)

Pump is stamped on cover "8mm" and "USA"

Is this a good pump, my oil pressure could have been higher.

thanks dave

that'd almost certainly be the Melling pump. lots of racer guys use those. i have no experience with those in T-IV's (as this thread has emphatically demonstrated!) but you should get some responses from the guys who -so- have experience (Brad, especially) when they check in after working on their cars all weekend ...

(but i'm becoming even more convinced than ever that if you do, indeed, have an oil pressure problem (of which i am as yet unconvinced) that it is not oil-pump related.)

As Long As it's out, tho, this would be an excellent time to make sure the inlet and outlets are match-ported to the case, and to see if the O-ring mod has been done, without which these pumps are historic leakers ...
