#1 Oil Pump Modifications

Post by panamacarrera » Mon Apr 01, 2019 10:11 pm

Hi All

My engine is being rebuilt. Just had this from the shop... “At sometime someone had die ground out the ports in your oil pump.” Anybody heard of this as a mod on the V12 engine? What benefit might it give?

Photo to follow tomorrow.

Cheers!

Hi again

Here's a photo pf the modification we've found on my V12's oil pump...

Any ideas why someone would do this? For what benefit?

Cheers!

Nigel

The only thing I can think of is that it would/might reduce turbulence in the oil flow and thereby improve oil flow or possibly prevent cavitation , although AFAIK cavitation is more a problem with impeller type pumps rather than gear ones

As Christopher says to improve flow.

I've certainly seen this recommended and done in 6 cylinder oil pumps but I have no experience with V12 ones. I doubt it has done any harm.

Thanks Chris & Andrew.

I've decided to go for a new oil pump. The car seems to have had oil supply problems in the past and this modified pump can't be ruled out as a culprit.

Thanks again guys
