Remote filter oil pressure issues
Turbo Mini Forums

Guys, I know many of you on here are running remote oil filters. Ive been running one for a while without problems but the car hasn't been used for about 8 months. I started it yesterday and found I was getting low oil pressure (idling at 35psi and dropping to 20 with a rev). I changed the oil even though I didn't have a new filter (stupid, I know, but was desperate) and its still the same. Just thinking about it today, a clogged filter would cause big problems in this setup since the oil is being sucked though. Im obviously going to put a new filter on (it might not be the problem at all but needs to be done anyway) but has anyone had any similar issues. Any thoughts or suggestions would be greatly appreciated. Im not sure if im clutching at straws with me filter diagnosis

PS
The engine has seen very little action since it was built so im hoping the pump should be ok

Sounds like the pressure release vale might be stuck a little open.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

I tried that first, it seemed to be moving freely.

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Sorry yes, I mean oil pressure.

No work was done since last driven.

Yes the filter is between the pickup and the pump. That's why I thought that if the filter is a bit blocked that the pump is struggling to pull enough oil through when the revs raise.

The question is why it might be blocked. But filters are dirt cheap, try a new one and see how it goes, or just bypass the filter completely for a test.

If the relief valve is good, then hard to know what else would cause the strange behaviour other than a pickup problem.

is the remote filter full flow? or does it have a relief valve?

if its full flow it might just be down to the oil being thick

How do you install a filter on the suction side of the pump?

Success, new filter and its a 50psi and stays there.

Id be interested in seeing your setup? Do you take a feed out the sump and stick it back in the gearbox at the back?

That’s exactly it stevieturbo, you explained it better than I could. Its an autotest car, so the gearbox creates a lot of swarf and other bits when it goes bust, so the idea is to filter the oil before it gets to the pump and goes through the engine. It very common amongst autotest minis (in fact I don’t know any not running it) and works very well. Sorry, I don't have any pics with me.

I see!

I see!

Three times apparently!
