how much labor for Rear Main Seal replacement?

I have oil leaking from the Rear, main crankshaft seal. How much labor is involved with its replacement and what else should I do while I'm in there? Giubo?

If I were to go to an indy, how much should I expect to pay?

Thanks.

I am guessing that you have an e46, and if so, the labor should be around 8 hours. Multiply that by the labor rate of the shop/tech of your choice. M3 smg rear main labor is around 13hrs.

I just read that using M1 0W-40 can contribute to the start of leaks. Is this true? If I switch to European Castrol or OE oil, will the leak slow or stop?

I'm dripping 2 drops daily while parked, but I haven't really had to add oil, yet... Will the leak get worse quickly?

If M3's RMS takes 13 hours, why other e46 should take just 8??? There is no difference between M3 and any other RWD e46 in this matter.
To replace the RMS it is necessary:
1) remove exhaust,
2) remove driveshaft
3) remove tranny
4) remove clutch and/or flywheel
5) replace the RMS
6) put everything back.
Inspect all removed parts and replace if necessary (guibo, tranny mounts, shifter bushings (if MT), central support bearing). Inspect the tranny for leaks from input/output seals, as well as shifter shaft seal (for MT). Replace seals if necessary or preventatively. Inspect clutch/flywheel, replace if it is time (for MT). A good time to replace starter (if it is 100K+) and post-cat O2 sensors. Inspect differential for leaks, inspect rear subframe and all bushings there too.

SMG Trans has a bit more hydraulics than your typical '01 330 Ci. Put that somewhere between 1-4 in your plan.
