my son has a 1991 1.4L ford escort, it has been standing for a several weeks
and now after running for a few minutes the oil pressure lamp comes on,
after checking in the manual it indictes a fault pressure releif valve bu
does show you where the valve is situated, can anyone out there point me in
the right direction.
The relief valve is usually in the oil pump it-self.
I really don't think that's the problem you are having. It almost
sounds linke the pick up screen is getting blocked by sludge or
carben. Try changing your oil TWICE in a row, and see what happens.

If it was ok the last time you ran then it is possible thr prv is sticking
open slightly and it may be worth taking it out and giving it a good
clean.Sometimes its the oil pick up in the sump thats at fault and if it's
really gummed/clogged up a few oil changes with a flush wont cure it.You may
have to remove the sump and take the pipe off to give it clean out but if
you think the oil prv is suspect then change the pump while you have the
sump off.If you do go that far then clean out the breather system as well
and clean out the oil trap/filter that fits into the air box.CVH's are
terrible for oil emulsification if you dont change the oil regularly or
leave them stood,i flush and change the oil in mine every 4-6 months
wheither it needs it or not.
