Have you got oil pressure?

My question too.
There have been problems lately with new oil pumps failing to seal on the gasket, because there's now little or no chamfer on the corner of the pump flange. So the pump can sit on the corner radius in the block, instead of sealing on the gasket.
I have just gone through this drama with someone's motor. Even a thicker gasket didn't fix it. So I ground a decent chamfer on the pump and used a stock gasket.


I bought a cheap oil gauge when I was replacing mine, because I was afraid of this.Took the spark plugs out, attached the gauge with a battery and cranked it by hand and watched the pressure rise. I'd invest in a gauge, even if you don't mount it and only use it once, because it's far cheaper than replacing the engine


Yes that sounds like a good idea, I could a fitting and attach it to the block.
thanks.

Some MGs have the filter mounted upside down!

The fact that the oil pump was able to deliver some oil to the filter don't mean it has the power to force oil through under pressure...oil pump? pick-up? or lines?


I didn't think I had a relief valve as I was removing the filter I placed rags under it to stop drips and covered up another nut which I didn't see first off because I left the rags there until I refitted the new filter, It has two nuts the same size upper one is just a nut covering an oil gallery and the lower one is the relief valve.
The plunger came out easy with no scaring, looks new, spring measured 71.5 should be 72.5 and I put a 2mm washer under the nut, tested the filter again and now have oil in filter.
So I will order a new spring and fit it.
Thanks

I have a tiny rear entry SMC 1000 KPa pressure gauge, 1/8 BSP thread. I just screw it in for testing, where the sender goes. You can buy these or similar from any pneumatic equipment supply shop.


Ok I'm on it and will check them out tomorrow.
Thanks

Hi Rover mini bscc
I have found this on the dyno when doing testing ( mainly on unleaded fuel) and I do a run on full load and shut the motor down quickly it will run on and then kick backwards when doing this it sucks the oil out of the filter and leave it dry,but never seems to drain the pump, it just takes a few more seconds to get up oil pressure when you fire it up again.
Graham Russell


Hi Graham,
I've never noticed the engine kick backwards, freeway speeds 110-120 but always slow slowly to lower speeds, suburban at speed limits. Costs to much otherwise.
It's funny the first time I noticed it the filter looked like it had never been used.
Oil in the filter now with a washer under the spring for correct length and until I check the pressure and replace the spring.
Thanks
Darryl

Hi all,
I have been looking at a Scottish mini site and got talking to them about the lack of oil in the filter, and was informed that this in normal with Rover MPI's even though mine is a SPI it has a MPI block so all is well and no concerns with an empty filter.
Previous to that I installed an Auto meter oil pressure gauge fitted in under the dash but then decided to make a console then put in the oil gauge and also fitted a clock in as well.

Oil pressure runs at 80psi on start up down to 64 psi when warm under load and 40 psi at idle.

Thanks again for all the help.

Darryl

Thanks for posting what you found out mate. Helps people in future if they search for the same issue.

It might also be worthwhile to see the specs of the filter being used ( no idea but on a earlier mini say ryco Z418) Reason being there may be a model that has anti drain valve.. eg on the remote locating oil filter kits sold by mini spares the z62 comes as standard but a z63 is the same beastie with antidrain...... both are mounted vertically though and both open the bypass at the same pressure) and if you do this make sure the volume, bypass opening pressure , thread type etc are all the same. But it sounds as if you keep a good eye on the pressures etc so maybe no need to change a thing ,... From another Darryl
