S60 Low Oil Pressure warning light

Post by **precopster** » 01 Jan 2012, 16:45

Has a guage EVER been hooked up to the block to determine the accuracy of your oil pressure sensor?

jimmy57s experience on these fives is what has saved me countless times. He always comes up with odd solutions that are not in the realm of experience of other users.

You know I chased one one time that would turn on the low oil pressure warning when started on a very cold morning and driven off in seconds or warmed up and revved.
It was checked and oil pressure would be fantastic.
After it was checked a few times the pressure switch was changed and it was repaired. I took the old switch apart and didn't find anything but did figure out the switch looked far more complicated than need be.

Many thanks for the information and suggestions. One rather worrying comment from my Volvo dealer is that the joint between the intermediate section and what is above it appears to have been sealed with black liquid gasket insted of the pink Volvo supplied liquid gasket. Is it a very big job to get at the intermediate section?
I will certainly try the oil cooler cleaning, Thanks again everybody, Alan

Removed the oil cooler and checked, nice and clean, no sludge.

I think I have run out of things to check now.

The oil pump was suggested by one member so I
may try that next, or just give up and scrap it.

Volvo dealer said the cold oil pressure at idle was 30psi

Thanks for all your efforts, Alan

The oil pump itself is not VERY hard to remove, just a little awkward where it's located. You'll need a good torx set for the three front bolts and a GOOD 4mm allen preferably with a socket adaptor to dismantle the rear screws which reveal the relief spring. Also you may want to have the crank nut broken by a garage or use the starter against a long breaker bar to crack it.

Thanks for the reply, It is the cam timing that I am a little worried about - and the cost of a new pump, over £200

I seem to be throwing as lot of money at this car.

Volvo dealer does not know what it is but want to take the head off

I may have one last try, Thanks again, Alan

One thing I did notice with the oil pan O-rings is that the seals on the pipe from the oil filter housing to the oil cooler (in the sump) did not seem correct, I asked about this at the Volvo dealer wher I bought the kit but the part numbers were correct.

The recess for the oil seal in the sump where it exits to the oil cooler was MUCH bigger than the outer diameter of the seal which is not an O-ring, it's a bit like a "Hula Hoop"

The one that came out also has a smaller O/D than the recess, but was longer than the new ones supplied by Volvo.

Can't advise you on those seals as I don't have experience with sump mounted the oil coolers. You won't have to touch the VVT, just mark the cam belt and place it back exactly on the same markings on crank and cam sprockets.

The failure rate of oil pumps is very low on these motors. In any case I wouldn't have a new one on hand if I were you, just buy a oil pump seal kit (crank seal is extra) and have the internals checked. There may be lots of sludge and buildup. Also you may want to order a new relief spring. Who knows, for the cost of a relief spring and seal kit your troubles may be over.
