Was out with the local Boy Scout troop and my son camping over the weekend, got onto a rough road that got out my plastic skid pan on the way in, on the way out caught my oil filter housing and bumped it enough that it seems the o ring between the oil cooler and engine block, bulged the o ring enough that it lost oil and oil presure. When the light came on I cut it off so no harm is been done internally I hope may have gone 40 feet from when it happened and when the light came on.
Question, there seems to be one bolt and a huge one at that that goes through the oil filter housing and the oilcooler holding everything to the engine block, is this right? Does anyone have a pic showing all of this assembly? Last but not least who has a pan that is stronger than the stock part made I heard of this somewhere in the past but don't know where to look now.
Thanks for all replies.

I've got copies but have failed miserably in getting them posted online. If you wish I'll snail mail them to you ASAP. Get back to me with your address if that's the way you want to go. The two jpg's that were in a reply, one in Swedish, and the other is a page that I have to send to you. My other page from the green books shows the correct oil cooler for our cars.

I hope these pictures can be of some help:

I truly hope you cut the power to the engine before it was too late.


I'm gonna go and see whats making my engine run so "bad". It runs well, but soo bad milage I cannot believe it. And when accelerating, it sounds just like a exhaustgasget is leaking, but it only appears at specific rpm. Almost like valves clattering. I don't wanna sell it, I love it. But this cannot go on, I'm thinking of swapping it for a 960 with 2.5E 170hp instead. I've got a 3.0 204hp now. Car has just over 80k miles to it.

Any ideas folks, does the 2.5 run cheaper? If so, I guess I would have no problems finding someone who wants to do a swap.

ehm, got a bit away from the subject there. Anyhow, good luck Poolman!

You have helped me now lets see if I can return the favor, In the pics you sent there was a lot of oil on top of your engine and even down in the spark plug holes,where is all that oil coming from. My car had a little like that but it has gone away since using Auto r-x , this stuff works and can clean the engine from the inside out, does a great job check out there web site. Back some time ago I changed out my timing belt and found that the last time it was changed the intake cam was left at 1 1/2 tooth retarded from what it should have been. My power was terrible, after geting that straight the power and mialege were greatly improved, also I changed out the knock sensors and that helped with power and fuel milage as well. Car now has 210,ooo miles on her and hasn't run this good in queit a long time. Have you tried a motor vac on the car, sometimes the valves can become encrusted with carbon and the injectors can not be up to par, the motor vac system will clean out the entire fuel system from the injectors to the cat system. Have you ever replaced the o2 sensors, these can wreck havoc on the mileage on these cars.
I'm not saying that you should do everything I'm pointing out, just areas that cause problems on these cars sometimes that do not render codes that will give the feed back thats needed to rectifiy a problem. Another area that comes up is the thermastat in the air filter housing being stuck causing hot air to come through,
What kind of milage are you getting you should be getting somewhere around 18 to 20 in the city and anywhere from 24 to 28 on highway, this is an average of what I have seen on these vehicles. If I can be of further help, you have my email address
Thanks again

Thanks for the reply!

The oil around the ignition coils and in the holes were due to the oil cap, its rubber seal had never been cleaned. And i've noticed that you have to wipe both the rubber and around the hole clean after filling oil. Then it will keep tight and will not leak. I have blown out all oil with compressed air and had the whole engine compartment cleaned since then. I had my timing belt changed quite recently at a authorized volvo shop. But i'm thinking of having it checked once more, just to be sure. And I'm not in the economical situation to afford buying new knock- and o2-sensors just to "test" if they are the cause.

And I know, its not easy to test them. If its even possible to get accurate results.

I've tried filling her up with higher octain fuel, ran on 95 before. Now it runs on 98. But there is no difference in mpg. I have no tool for converting to mpg right now (at work), but it almost runs at 2liter/10kilometer. And thats far away from what volvo specifies at 17 MPG city and 25 MPG highway. 17MPG is something like 0,925 liter/10km and 25 is something like 1,37 liter/10km.

Thanks for the timing belt tip, that could be it!
Got to return to work now,

Thanks for the reply!

From the bottom up: the hallow bolt, one -o- ring, the adapter for the filter, a large -o- ring, the cooler, a gasket and the block

I just looked through the two green books I have on the B6304 but they showed little useful for you except the scanned image I've sent along. If you can wait till tomorrow I can go the library with my fiche for parts and at least get you an exploded view diagram with part numbers. I have wondered about this very scenario everytime I do an oil change. Hopefully it won't be too difficult to get this episode behind you.

Evidently I don't know how to include a jpg or tif so it may be till tomorrow on the pictures. Sorry.

Thanks for the help, it will be greatly app, gonna have a few days to look over what surgery I have to perform because of the dang cold weather that came in here over the weekend, it's gotta warm up. Thankfully we didn't get the heavy stuff that hit north of where we are.
Thanks again

Hi Poolman,

I'm leaking oil on the 95 from the same series of "O" rings. I'm fairly sure it's leaking from the upper most large "O" ring. Please let me know what the part numbers are for those "O" rings if you do all three. If I ever get the 95 running right again, I'm going to change out those three rings to stop an annoying drip I've got.

It sounds like you probably didn't do any engine damage.... "Phew"!

I don't know of anyone that makes a 'metal' pan for the 960. The 850/S70 yes, but not the 960.

Sorry to hear about your mishap, but I suppose it could be worse! I take it you weren't anywhere near the northeast! I looked through the CD-ROM pdf files for my V90 and saw no reference to the oil filter or it's housing. I wold imagine that you may have to find a green book for this one. Good luck.
