Hello, Thanks for your reply, those "O" rings you describe all fit fine, but in the kit Volvo supply there are four identical tan coloured seals, two for the turbo lines and the other two are supposed to fit the pipe that connects the oil filter housing to the outlet to the oil cooler that...

Just bolt on an oil cooler - without a water supply it won't cool the oil, but will keep the oil in

I think I have just spotted the problem. While replacing the seals in another V70 I noticed that Volvo are supplying the wrong seals for the pipe in the sump that connects the oil filter to the oil cooler. On the first engine I could not compare the old seal with the new one because it had crumbled....

Hello, I have the same problem with TWO cars, a 2001 V70 Turbo and a 1999 V70 non turbo. The odd thing is both were unused for about three months and had no oil pressure problems before. Now both of them give warnings after four miles for the 2001 and eight miles for the 1999. Volvo put a gauge on m...

It appears that V70 have a problem with low oil pressure when they get to about 150K miles, and the main cause is said to be the seals and O rings in the sump. I have the “NO OIL PRESSURE STOP problem on my 2001 V70 2.4 turbo, Volvo confirmed the pressure does drop to zero. I removed the sump, clean...

I have the same problem with my 2.4 V70 Turbo. Sump was full of crud and the little sleeve seals on the pipe were very brittle. I cleaned all the sludge out of the sump and square drain tube in the sump returning oil from above which was totally blocked. Replace all the seals and O rings with a kit ...

Thanks J5T. It would be nice to just fit a new pump, but they are over £200.

I am thinking that I am flogging a dead horse, and don't want to risk throwing away another 200 plus pounds'

I will take it off as you and Precopster suggest and see if I can get it checked, or see anything obvious.

Hello again, if these seals fail do they cause low oil pressure?

I was assuming they just stopped oil leaking to the outside world, but they can cause loss of pressure can they?

Thanks Precopster, I will have one last go. There was an oil pump seal repaced 15,000 ago when it was blowing oil which was traced to blocked breathers It looks as though the was OK until quite recently when it was unused for a few months and then gave low oil pressure messages, BUT I got it after i...

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 wher...
