Why one needs to remove the oil pan to do it? I'm not familiar with your car, but I can't beleive it can't be done without oil pan removal.

I was quoted 6 hours labor to remove the pan for the M103 6cyl. $450 in all, 400 labor and 50 for tapping the plug.
Got the JB Weld and the oil drain valve is being overnighted, needed also an adapter for the 300e drain valve. I will have it fixed by tomorrow evening.
