I had a front engine reseal and new belts. And an oil change 10/40. New oil pressure sender uint. The neddle starts at 1 when I turn all the warning lights on. And has then been sitting between 4-5 ever sences. This was the case last time when i replaced the sender, and the lug snapped, I managed 2 get it 2 work 4 a few days till the repire failed.

The last few days oil pressure been sitting at 4 the 5 under acceleration, then back down 2 4.5 when braking.

I was coming down a steep hill with a tight shape left turn. So I drop it in 2 neutral and braked 4 the coner, noticed the light come on and the middle sitting low, under acceratiom the needle raise again. But each tome iv came 2 a junction and have sat idealin the light comes on? Iv check the oil earlier and it was full. I just checked now but it warm so can really tell. Yet. Neather off the readings iv been getting sound right, high or low?

It should read 4 - 5 when cold or high revs. When its hot & idling it should read around 2. Was the crank pulley removed when the seals were changed? Check the bolt, if it comes loose the oil pump can stop turning.

I thinking it was something 2 do with the work done, buts it's only just droped down after a few days prob about 100 miles off use. The oil was always sitting at 4 Bar, the seals were replaced not sure if the pully was removed. I would I notice a loss off oil as well?

I had the gear box oil changed and iv noticed a strange noise, at low revs sounds like a dry disc spinning. But I'm sure this sounds like it coming from the rear so im thinking it tranmisdion related? Around 1400-2000 revs about 15-20 mph. Can't say iv heard it in a high gear at them revs.

Thanks.

At around 7pm I turned the car off, I let it sit 4 45mins and turned it back on the oil preuser was sitting around 1.5 bar. And after 15-20 secs the light came on.


Well iv just ran the car 4 30mins from 10 -10:30 driving and sitting. So now the cars had 3 hours 2 cool down. I checked the oil, It was a bit dark so I couldn't really tell the oil level on the dip stick. Even from using tissue, there was at least 3/4 on there but it was full early, 50miles ago. But the engine was still warm 2 thouch but not hot. Turned the car over and preusser raised 2 5 bar and stayed between 5-4 bar. I'm guessing that the oil would have warmed up withing a few mins or at least once the cars at running temp? So I should off seen it drop between 3-4 at ideal and not 4? But the neddle starts at 1 not 0? Is this right? Or is the neddle one bar high? So 3 is really 4?


I'm thinking that maybe the relif valve is sticky? Keeping it high, then when freed up keeping it low? Is this possible ?

A sticky relief valve can cause a loss of pressure but I would still check the crank pulley nut first (24mm socket).
The 'disc spinning' noise you can hear at the rear is probably a brake disc shield.

Thanks, the crank nut is located were? do the belts need removing?

As 4 the disc noise it stops when the clutch is pressed in. Can be heard from outside the car.

How long should it take normally 4 the oil 2 warm up? And 2 setal around 3 bar.
Thanks 4 your time

You need to find a good mechanic Terry. Crank nut is crazy tight so you won't be able to check this on your own. Check for oil leaks around the crank seal. (pulley at the bottom on the end of the crank!) If the seal was damaged when fitting that could effect pressure.
