hi guys I have my m70 still in the 1988 donor car, I has a serious oil leak from the rear of the sump about 6 inches from the bell housing face. I have been told that the m70 needs to have negative pressure in the sump, or it pumps the oil through the intakes regardless of the condition of the vcv valves , this is what mine is doing so smoke everywhere but compression is good, so I thought I would remove the sump first and fix that leak and then attack the vcv valves, I have also been told by a bmw mechanic that the sump has two bolts inside the bell housing of the gearbox and so you have to remove the gearbox to remove the sump, I have the car up on ramps and I don't understand what he means the sump seems to stop at the bell housing flange, can anyone confirm the existence of the two vertical bolts in the bell housing.
Also the engine just started turning on the oil warning light at idle, but its full of oil or maybe a little over full it does not knock it just turned the warning on so I shut it off, could this be low oil pressure caused by loose rocker oil feed banjo bolts that I believe is common. Any help much appreciated as i'm trying to sort his engine before I pull it for my project.

Check this out. Try the two valves first.

Thanks Jim for the suggestion on the valves, but the sump leak is a major as even raising the front of the car pours oil out, I don't want to run the car like that or I will kill the bearing from lack of oil, can you confirm the existence of the bolts inside the bell housing, I'm trying to sort this leak in the driveway as I have no garage, so I'm trying to leave the GB in the car if possible the manual says remove the trans, but a post I found on the bimmerforums suggests it can be done with the GB installed.

Thanks Jim I have spent 10 mins on google and finally found this, http://www.bimmerboard.com/forums/posts/204310/ which answers my question trust BMR to put bolts where you cant get at them without drilling holes or removing the GB, I don't really want to cut holes in my sump so I might try removing the radiator and just unbolt the motor and exhaust etc and move it forward from the GB a couple of inches and I should be good.
many thanks
Graeme

yeah the pics tell it all, the holes are the easiest way to get it done, otherwise to separate the engine from the trans can be an ordeal, you will need torx sockets e10 and e12 and about 4 ft of extensions to get to the bolts at the top of the trans, because the trans has stiffening ribs on either side of each bolt. And if you strip one all bets are off
