High Volume Oil pump

Post by alpha318 »

Hello all!

I own a 98 Volvo V70 XC, B5254T, Chassis # 505073

I'm in need of some information.
Has anyone had any luck of finding a High volume Oil pump for a P80 Volvo?
Any posts/write ups worth mentioning?
Any help would be fantastic!

Are you talking about the little oil pump on the crankshaft? I was evaluating the replacement of its seal recently, so had done some research:
I found this oil pump rebuild info for an unknown year P80. Note that some of the pictures are sideways or upside down.
cn90 has good info about reseating the seal in this oil pump thread for a 1993.
I saw the pump available for $345 recently. I believe it was at both FCP and VolvoPartsWebStore.

The Volvo white block Oil pump is a Gerotor pump. I don't think there is any way to change the geometry and make a higher volume pump that will fit in the space provided.

There is rumor that the RNC Oil pump is bigger. You might look into building a RNC block and install it instead of the RN block. The RNC has a lot of other technical advancements over the RN block. Including better coolant flow in the head.

Gerotor pump.
