Oil Base

[Brent Kasl <kasl100@navix.net>]

I am in need of the oil pressure relief valve and spring that fits the
S5 oil cooler filter base. I have the base and oil filter housing but am
missing the valve and spring and need it. Also, on my S2 block, I notice
that the holes that the oil uses for passage does not match the path
between the original oil filter base and the oil filter base on the S5
setup. I thought these were interchangeable and am wanting to install
the oil cooler. Should I be concerned? Thanks for any feedback, Brent
