Excessive clatter on start after sitting using Mann filter

It is all about keeping the oil on the top of the engine. Without the check valve in the oil filter or with a crappy check valve on the oil filter it will drain immediately. With bad O rings it just drains a little slower.

That gravity thing comes into play.

OK that makes total sense. So the o-rings, if bad, will allow the oil to drain out even if you have a check valve, thus giving me that sound at startup? I suppose then I still have a bit of air coming into the engine oil at all times, it just isn't as bad as others who notice a pronounced noise at all times? Now that I think about it, the engine is a *little* noisy after startup as well but by the time I reach home is quiet.

And replacing the o-rings should help in keeping the oil at the top of the engine. Ok I think I see now. It sounds like a time consuming job, I can't find any pictures of the writeup, just text, so I will try and take some. There was a writeup linked on here but it seems the link is now dead.

Also here is what the engine sounds like at idle, does it sound OK or indicative of bad circulation? I apologize I really don't know what to listen for here.

Edit: I suppose I need to post the video...

This is the only writeup I know of. If you wanted to shoot some pictures along the way and do a writeup it could be the best ever.

I have a 30750383 lower sump O ring kit and a tube of Curil K2 sealer

Lee, isn't that 30750783?

Lee, isn't that 30750783?

I suppose it could be and now that you point the number out it likely is. It was written on the bag with a magic marker and it wasn't all that legible.

Just got back from a trip, started the car, usual clanking sound. Looked under the oil filler cap and saw just a bit of oil. Let it warm up about 3 minutes, little bit more oil. Also noticed a tapping continuously. I haven't really noticed it being this loud before, but maybe it's just because I am more in tune with what to listen for.

Drove home, around 25 miles on the highway. Looked under the cap again, lots more oil but the tapping is still persistent. So much oil that it was throwing it out of the cap, and splattering it on the spark plug cover. I will try to get a youtube video of the amount of oil once warm tomorrow. Is this tapping the lifters? If so can it be corrected or has the damage already been done?

It actually sounds like it did when I didn't have enough oil in the car, then added oil and the sound was quieter.

Sadly, there was another writeup here in our database. I think it was Pfeener who did it, because I had it pinned. I found it to be a better writeup than the one at Volvoforums. I've searched for it but can't seem to find the original post. I got as far as...

"Oil Sump O Ring Replacement Procedure
I have a 93 850 so its a non-turbo and has an oil level sensor in the front of the pan so many people will skip the oil sensor step and add steps to disconnect the oil cooler lines…

... in my search which indicates it was done on March 14, 2006, but I don't have the skills to get any further. I dunno if maybe Matt or someone else can pull that from the previous build of this website...
