Oil pressure light and oil pump no longer produced

WhiskyRB26 · Post by **WhiskyRB26** » 24 Jun 2025, 17:09

Hello everyone, I have a problem with my 1999 V70 2.5t and I need your help. On my V70 I have the oil pressure light on/off on the dashboard, I first thought it was a problem with the oil pressure sensor but even after changing the problem remains. I then disassembled the oil sump, changed the seals, cleaned the suction line and the sump and reassembled everything, but I still had the same problem. I went to see the mechanic across the street and he said the oil pump was starting to die. The problem is that part number 9207950, which is the one for my pump, is no longer produced and can't be found.

So I have several questions: do you know if it's possible to fit the reference 30650144 oil pump that's supposed to go on V70 turbo models from 2000 onwards? If it's not possible, would you know where I could get the pump to fit my engine, even if it's second-hand? I also know that there is a story about a spring that generates a pressure problem on older volvos, do you know if this could also be the case on mine and if so where is this spring located?

Thank you very much for your help.

So this is the pump you are talking about:

https://www.volvocarstorontoparts.ca/p/ ... 07950.html

Strange thing is the other part number you show is also listed for a 1999 V70 GLT (2.5T).

https://www.volvocarstorontoparts.ca/p/ ... 50144.html

Then, the stranger thing is if you look at the parts drawing for that year, there is a engine number break for the oil seal rebuild kits, Item #2 on the parts list:

https://www.volvocarstorontoparts.ca/a/ ... 76371.html

I would go back to Volvo and ask them if the later one now supersedes the older number. Then the other option is the gasket kit to rebuild the pump.

Question: how many miles on this engine? are you sure it was getting good maintenance throughout its life? What process you mechanic used to diagnose the pump failure? We're you trying to change to a more viscous type of engine oil?
For the car of this age, I would probably try to locate a used oil pump and try to see if there would be any difference (hope you are doing all this work yourself since it probably 4h job by the book).

I called the dealer and according to him on the software this part number does not replace the one I have. Concerning the gasket kit, can it really work if there's no leak?

Around 355000 km/ 220586 miles. I tried the 10w60 before disassembling the oil sump without success. The mechanic took the oil pressure directly from the pressure sensor. I'd like to try a used part but I can't find any in France or on a site that will deliver to France.
I've seen parts in Ukraine on a website called avtopro but I don't know if I can trust this site and from what I understand by translating the page they don't deliver to France.

Oh wow. I would imagine that you being so close to Sweden would make it easier to find good used parts. If everything fails, I can try to ask my friend in Ukraine to buy and ship the item for you(not sure how much shipping and his commission would be)

If you have the possibility of contacting him to find out if he would agree to do it and how much his commission would be I'm not against it because at the moment, apart from having to buy a complete engine, I don't know what the solution could be.

The gasket kit includes new seals. So it is possible depending on the wear on your pump it could just be tired seals causing the issue. I have a kit in the garage. I think I bought it for a new seal as you could not buy whatever it was separately when I was working on the main seal leaking. I will take a picture and post it here to let you see what is included. Unless your car has had a lot of missed oil changes, the mileage is not terrible for an oil pump in these cars.

I don't understand the oil pump compatibility issue and so many part numbers.

Lets first see what parts scot850 has in stock. Please send the link of the part that you were thinking to buy from Ukraine and name of the town to where the shipping should be done. I will ask my friend to look into it.

I don't really know how to explain it, I'm just basing myself on partsouq, skandix and the dealer, which show a change of reference without the new one obviously being able to be put in place of the old one. There are indeed visual differences but I don't know if that's enough to make it really incompatible, here is some pictures to show the difference.
