Oil Pan remove and install, Oil pick up o rings. 850

Hi, I'm about to work on a relatives 850 and I was wondering how hard it is to remove and replace the oil pan. I guess his 850 makes Valve noise at start up and it needs the oil pump pick-up tube o rings replaced??? Thats what I'm told anyway. Any thoughts? Thanks.

Oil Pan remove and install, Oil pick up o rings. 850

It's not easy. If you're doing it in a shop on a lift, then probably not too bad.

The power steering lines run under the back of the pan, and the subframe interfers with the front. You need to support the engine with an engine hoist, and then lower the subframe. The front of the car will need to be supported by the frame, not by the subframe. The engine mounts that interfer with lowering the subframe will have to be undone. I was able to move the power steering lines out of the way far enough by undoing the support brackets. The required o-rings come as a kit. There will be a few extra in there. The ones that you will need are for the oil pick up tube, and two that go between the oil pan and intermediate section. If there is an oil level sensor going in the side of the pan, you will probably want to remove it as well to get access to the oil pan bolts. There is an o-ring for this that will not be included in the kit.

There is no gasket between the oil pan and subframe. Volvo uses a liquid gasket, and you will need to get a tube of that. To remove the old liquid gasket material, I used spray on gasket remover. Don't use scrapers or abrasive materials to clean this surface. The intermediate section was clean, I only had to clean the oil pan mating surface. You will need a small roller to apply the liquid gasket (as shown in Haynes) for reassembly.

This is supposed to be the fix for this problem. Unfortunately, it did not fix mine. However, I have a '93, and these had an earlier design lifter that were more prone to this problem apparently. At least, that is what I gather from looking in the forums.
