The 'E' Type Forum

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!

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

Nigel
