Filter Head Question
Turbo Mini Forums

I've done a search, but not found the answer....

Am I correct in thinking that the oil filter head as a preasure relief valve, resulting in unfiltered oil in the galleries until the preasure is up?

Minisapres offered (NLA) a billet head with no relief valve.

Is it worth while and/or possible to remove the valve from a standard one so that you always get filtered oil to the galleries??

You can weld up the valve in the standard one. Just takes a little longer to build oil pressure.

If something is worth doing, it's worth doing half of.

No - there is a pressure relief valve but it does not affect oil pressure build up. If the oil pressure is too high it will open and thereby bypass the filter.

So leave as is then.

Thanks

I believe its more for when the oil filter is blocked up.

If something is worth doing, it's worth doing half of.

defo block it off.

as has been said, it only opens if the pressure is too high letting unfiltered oil through.

a blocked filter/shagged oil is something that hopefully no one on here would let happen so its not needed

Next querstion then - what's the best way to block it of then??

I've seen some that Steve has welded. I was going to have one too.

If something is worth doing, it's worth doing half of.

you can weld it or tap it and put a bung in, iirc 5/8 unf works.

or you can buy a bling billet one from keith calver, swiftune or sh engineering for about 45 quid.
