Excessive oil pressure

[henris42]

Hi, I rebuilt the V6, but now I have excessive oil pressure. So much that oil comes out from the turbos.

I tried adding mode washers to the oil pump regulator, but I'm starting to think that maybe there is too much crankcase pressure. (I have now 5 washers there and the meter is still bit under 5!)

Any ideas what to check? I gather its supposed to breathe via the heads, could it be there is wrong head gasket or something - maybe there is a blocked passage?

That's not an easy one without seeing it but correct oil filter ?

The oil pump itself does not produce pressure, it's the tolerances between components . If it's producing a high pressure then it has a restriction. If it's coming out the turbo's it's not getting somewhere else for whatever reason. As mentioned the filter may be incorrect. I'd want to check oil ways, maybe a gasket blocking a gallery.

I assume filter is correct, its Wix WL7064.
