oil pressure starting problem
Turbo Mini Forums

when i start up the engine it takes quite a while for engine pressure to get up, changed oil pump as old one not in great condition, but still have same syptoms, what might cuase this, new gasket and torqued to right spec. have an oil cooler with quite a bit of pipe on it might this cause it, since i moved the oil cooler lower in the engine bay and added a bit more tube the problem has popped up. but not sure if it this.

yeh,and straight not on an angle, you say quite a while, how long roughly for full pressure to get up, have you tried another gauge to test ?

oil cooler is long ways with unions heading straight up to the sky, unions connecting to the oil cooler are 90 degree bends then to the pipes, takes about 5 seconds to reach pressure and i have a 25 psi oil pressure switch that tells me the same, oil pressure gauge works, oil pressure good when up to pressure even when hot

I have my Oil Cooler on its side with a fair bit of oil pipe and it gets pressure straight away. When cranking the gauge moves up and gets to pressure instant. As seen below. Strange one this, is it a new cooler? Try it without the cooler

the only thing i can think of is its draining either the pipes or cooler when shut off. Only other thing could be sticking oil releif valve, have you got decent oil in.

Hi,
It can do if it's jammed in a partially open position...
Cheers,
Gavin :)

update for other people, think i have found problem after some more investigating, if you have issuse like mine and suspect o ring inbetween block and gearbox then run the engine up for a bit if safe and then drop a bit of oil from the sump if it has little air bubbles in it then most likely o ring or duff pump, was told this by a friend, sure enought i have little air bubbles all through my oil, i hate my mini sooooooo very much at the momment

bugger :(

i think its pretty unusual for the o ring to give trouble provided its been fitted.

also check the oil pickup for any pinholes especialy round the joins, and check the gaskets (both sides) for the pickup.

also as mentioned check the oil pump gasket, and check the backplate on the oil pump incsase the air could be getting in there.

ye i am going to check pump before sliting block just incase its an easy fix will update when problem found and fixed

problem was a very blocked pick up gauze

i hate my car it still has the problem same as before, what could possible cause oil pressure to take so long to get up to pressure but once hot it still maintains really good oil pressure, i have put new pump on, cleaned pick up pipe gauze, new pump gasket, new o ring inbetween block and gearbox, how long should it take for the oil to come out of the block where the oil goes to the filter while cranking over with no plugs, as going to check this to see if its a feed problem first
