Bj8 Oil Pump

[James A]

Hi again all!

The point is reaching where I have to decide which way to go in regards to replacing my Oil pump and the last discussion ended up heavily into oil type (which has taught me a great deal!).

I am split between the Denis Welsh high pressure (suitable for road cars) which is a rotor type, or the standard gear type from ahead4healeys.

A part of me wants to go with the DW option however have had advice that you should stick with what was put on the car originally (I believe the BJ8 was a gear type).

Has anyone got a DW pump on a bj8 and are you satisfied?

Help!

Save your money , buy new guts for the original gear pump , when you remove the gear cover plate reface it using a glass block and grinding paste to make it flat again . Put it together with new gears . Voila done good as new with restored pumping power .

I'd buy the high output rotor type pump. They're better and more durable and they're is no downside.

Later cars had a stiffer drive shaft which cured the breakage problem the 100/6 suffered with. They had the rotor/vane pump from new as did all A Series.

I have the vane type in my BJ8 engine.

FWIW rotors are more efficient at low revs and when worn. A few scratches in the body of the gear pump and oil pressure drops noticeably.
