Still low oil pressure!!!!
Have just changed oil pump and have only got 40psi at idle when cold and 10psi at idle when warm. Oil is cheap brand 15w40 as i'm running the engine in, has new main and big end bearings, new rings etc etc. Have cleaned out oil pick up, surely it should be higher than that???

I'm pretty sure the sump gasket won't affect the oil pressure, but obviously slowly you will lose oil.
Fitting a CVH sump gasket with the engine in the car isn't an easy task...

Haynes manual says:
Minimum oil pressure at 80°C (176°F):
At 750 rpm . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.0 bar (14.5 lbf/in2)
At 2000 rpm . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2.8 bar (40.6 lbf/in2)
10 to 14.5psi is still a diference but nothing (I think...)

I think the turbo is ok there is a tiny bit of movement in the shaft and it does not smoke when running, but the true test is when it being drivin on the road which I can't coz its not mot'd, can't be mot'd til i sort out the oil pressure

when my sump gasket was leaking the car wouldn't idle properly when warm which i though could be a lack of oil pressure. i didn't have an oil pressure gauge at the time so my comment was just an un-educated guess

You cheap skate, buy some new bolts
If you go to a fastening plcae the bolts will actually have 17mm heads so they won't round off next time....

i think the bolts rounded off cause i was using a spanner to undo them. i took a massive breaker bar down to the scrappy with me and they came off the Fiesta in 2 seconds.
there were 2 mk4 escorts down there and they both were sitting on their discs so i couldn't get the bracket off from underneath

another thing to try:
Put a rag in the turbo compressor to stop it turning - but dont block it so air can still pass through! Disconnect actuator from wastegate so the turbo doesnt try to turn. Then block off the turbo oil supply, and see what the pressure is. This will eliminate the turbo as a cause.

Thats good advice!
Was urs on a new engine? What were ur readings?
Maybe a good way to eliminate is to take of the cooler sandwitch and put the filter on direct temporarily.

Oil cooler front side (where the oil filter goes into)
The flap I was talking about is on the back side (screwdriver)
But best way ist to try like Rick said. Remove the cooler completely and fit the filter directly to the block and see what happens. Oil cooler could also be blocked up inside.

Quick update..............tried everthing everybody has told me still very low pressure, just stripped down a spare engine I have and found this pipe
this is the pipe from the sump side of the turbo return into the sump, I don't have this pipe in my sump do you think this may be the answer to my low oil pressure

No, that just stops the oil running down the sump gasket edges etc, if anything it is a restriction on the turbo oil return.
I doubt very very much if thats the answer. Have you done as rick says with the Turbo?
