Works in progress - Conversion to turbo with a NA motor or 260hp no turbo. Say a prayer for me.
302mm brakes, IPD sway bars front and rear, QBM end links, MSD 6A ignition w/Blaster 2 coil pack, Jet Chip, Bilstein Shocks/Struts, R Springs. Hell I can't remember everything else.

EDIT: Darn we got off topic really quickly. It may help you to run a bit higher viscosity oil for a little while (10w-40) until you can get the leak fixed. I also agree that Auto-RX is incredible stuff and may do some good until you can get the problem fixed.

The RMS is a seal that is held in position by the friction of the rubber (or soft sealing compound) against the seal carrier.
There are no bolts holding the seal, there are bolts holding the carrier, but that has never been a source of leaks.
This may help your situation.
Make sure your PCV (Flame trap) is working properly. Pressure in the cranckcase will accentuate a leak, any oil leak.

at idle, does your car blow alott of hot smokey air out from the oil fiiller cap and dipstick tube?
if it does temporarily vent the crankcase, it is immoral and wrong but it could help alott. run your oil level as low as possible but still circualting to keep it off the seal, and use 50wt oil. and then of course replacing the rear main seal and getting the erg (blowby) system up and running asap. i have nerer tried the seal swelling stuff, what the heck, give that a shot too.

Yeah... I drive two manual T5's and other manual cars
Over here, hardly anyone learns in an auto unless they either cannot drive or they are very old. Most cars here are manual.

For years I insisted on driving only manual transmission vehicles. In my younger days ( teens, 20's and part of my 30's) I too thought AT equipped cars were for "wussies".
Then a couple of things happened:
1) I moved to Houston where the traffic is bad ( no , awfull)- no fun shifting from 1st back to neutral in hot stop and go traffic
2) The Volvo 850 turbo is actually hard to beat with an auto transmission. When Road & Track tested it they made the comment to the effect that the auto transmission was set up near perfectly to hit the power band of the turbo.
Anyhow - I do like manual transmission cars as long as you have enough space to run them up through the gears and back down again.
One new car I like design wise is the 2005 Mustang GT. I think I would insist on a manual tranny on it.
Oh yeah, what does this have to do with the originator's thread regarding a leaking RMS

I don't like that my 850 (first auto i've had in 3 cars) shifts unexpectedly sometimes (as with any auto) and of course the fix to this problem is:
1) Buy a car with gear-tronic or whatever; or
2) Buy a split window corvette with a 4 speed
As for the rear main seal, umm.. ditto!?

Yeah- we sure did hijack your thread
in my humble opinion, based on about >30 years of driving - there is no majic fix for leaking seals; leaking ac evaporators; leaking radiators; leaking heater cores; and anything else that leaks. In fact, there are no cheap fixes period... Now if you are trading the car tomorrow- that's another story. Me, I like my 850 and although I can afford to buy a new car- I cannot find one I like to drive as much
The RMS replacements will likely run between $800 to 1,000 US dollars if performed by a reputable mechanic. I do not envy you having to contemplate this.
Here's my own logic on the 850 - I am the original owner and the car is 10 years old. Things will break and wear out on a 10 year old car, the alternative for me would be spending $45K for a "comparable" new vehicle.
My best advice is search long and hard for a really good and honest indy Volvo mechanic shop. I was fortunate and found great one in Houston. He isn't cheap- but is less than the dealer. Most importantly, he has a passion for Volvo's and he and his technicians do outstanding work.
Good Luck !

the high milage motor oil like maxlife is formulated to soften the seals. might want to give it a try. I heard about the brake fluid too. It seems swallon up rubber a bit.
Try maxlife for two oil changes and see if that stops it.

I put a 50/50 mix of lucas oil and regular oil in the car and it slowed the leak. I think after another 3000 I will try that RX stuff. I just can't afford to fix the rms right now. Will the RX stuff clean the flame trap or should I do that seperate?
