The driveshaft seal, halfshaft seals and rear cover seals have been replaced. I took it back to the shop to trace a small leak two weeks ago. He replaced an o-ring that goes around the speed sensor, and thought he fixed it. It's still leaking, so I went back, and now he says the speed sensor is where the leak is coming from. Not a big deal, I can replace that easily. The questions is, can the speed sensor really be where the leak is, or is the o-ring still the issue? Second, should I buy the speed sensor made for the 3.46 LSD, or buy a new one that fit my stock diff? The part #'s are different, and from the picture, something else is different on the socket where the wires come in. Here are the links. http://www.realoem.com/bmw/showparts...09&hg=33&fg=10 http://www.realoem.com/bmw/showparts...31&hg=33&fg=10 In the first link, part #11 is not familiar, doesn't show in the stock TI part list. I am currently using my stock TI speed sensor in the E28 diff, and it works fine. So which speed sensor should I replace it with, or should I just try something else to fix the small leak? __________________ 1998 (July) 318ti, 5-spd OEM Armrest Blaupunkt Heidelberg CD50 CD Player/Compact Drive MP3 Player Diamond Audio 5.25" rear speakers Navman ICN 530 GPS BMWALARM.COM (with comfort settings) after market alarm system Magnecor 8.5mm wires M-Z3 Shifter/Momo Knob Burlwood Dashboard Stromung Exhaust X-brace Racing Dynamics Front Strut Bar Carbonio C.A.I. 17" Rial Rims Vader Seats/Heated/Lumbar Support M-tech Steering Wheel/Front Sway Bar/Front & Rear Bumper Depos/w 6500K Angel Eyes/6000K HIDs Clear Corners M3 Mirrors UUC Light Weight Flywheel/M5 Clutch/M3 Clutch Slave E28 3.46 LSD/Mcoupe Cover/E30 Flanges & Halfshafts UUC S.S.

That means the form and fit is the same for both sensors. I'm just gonna order a new o-ring and bracket . I can't see how the actual sensor can allow oil through it.

Looked very convincing that the leak was from the sensor/o-ring.

I stood right there under the car with him, when he pointed out the leak.

Here is my question. I can't remember if I used the stock speed sensor, or the 3.46LSD sensor. I ordered the stock Ti sensor, just because I knew the electrical interface connector would mate up. From what I remember, the 3.46LSD speed sensor had one longer and one shorter half circle part that went into the diff on both sides of the ring. The new sensor I just bought had both protruding half circles the same size. Would a 318ti sensor fit in the 3.46 LSD? I just don't remember which one is in there. __________________ 1998 (July) 318ti, 5-spd OEM Armrest Blaupunkt Heidelberg CD50 CD Player/Compact Drive MP3 Player Diamond Audio 5.25" rear speakers Navman ICN 530 GPS BMWALARM.COM (with comfort settings) after market alarm system Magnecor 8.5mm wires M-Z3 Shifter/Momo Knob Burlwood Dashboard Stromung Exhaust X-brace Racing Dynamics Front Strut Bar Carbonio C.A.I. 17" Rial Rims Vader Seats/Heated/Lumbar Support M-tech Steering Wheel/Front Sway Bar/Front & Rear Bumper Depos/w 6500K Angel Eyes/6000K HIDs Clear Corners M3 Mirrors UUC Light Weight Flywheel/M5 Clutch/M3 Clutch Slave E28 3.46 LSD/Mcoupe Cover/E30 Flanges & Halfshafts UUC S.S.
