I have one on my 1977 R100RS for about 300,000 of it's 412,000 miles at it works well! It will increase your oil capacity by 1 quart as well as cool it!

woodnsteel said:Y'know Les, I switched my airheads to synthetic oil and sold my deep sump oil pans. I sold ,em for $75 each, replaced ,em for $15 each and treated my motors to better oil. Something to consider.
les_garten said:I've always used synth. oil. But I'm thinking Deep sump and synthetic is the way to go. It's hot and Humid down here in the Soth of Florida!

les_garten said:Hmmm,
I might already have one then. I have a 92 R100RT. I saw a deep sump on ebay and it looked deeper than mine. Are you saying that 92 R100RT's had deep sumps on them from the factory?
Darryl said:HI les;
I have the flow through oil cooler which gives you the one quart extra oil capacity!
lkchris said:Deeper than the GS.
BUT, I previously assumed R100GS and now you state R100RT, so yes you already have it.
250cc more oil capacity than R100GS, 500cc more capacity than R80G/S with their "flat" sumps drilled for skid plate.
Use of synthetic will provide way more advantage than a deeper sump, without the ground clearance concerns and without concerns of putting aftermarket junk on your engine. IIRC the aftermarket dried up for deep sumps for "touring" BMWs after introduction of the deeper pan in 1981.
pmdave said:The deep sump does increase oil capacity, but it also decreases ground clearance. Even a medium sized speed bump may cause the sump to crunch down.
One other potential problem is the sump adapter, typically an aluminum spacer that goes between the block and the oil pickup to push the pickup lower in the pan. The bolts that hold the pickup to the block occasionally loosen, with the potential for allowing air to suck into the oil pump. Note: air is not a good lubricant for BMW bearings.
I have the stock sumps on my airheads, and agree with the greater advantage of synthetic oils, although I prefer semi-synthetic, to gain the best properties of both types. Regular oil helps keep the seals expanded. Synthetic oil maintains it's viscosity longer.
However, if you are convinced you really want a deep sump, I have one on the shelf somewhere. It has been slightly modified--with a bite out of one of the fins at the front--the missing piece is somewhere up in the mountains on a steep rocky forest service road. The sump isn't cracked, just a corner of the fin. I could probably find the sump, spacer, etc. and would be willing to pass along to you for the price of shipping. If so, send me an Email.
If you're really anal-retentive, you could either:
a. grind off the fin on the other side to match
b. weld up the missing corner.
