James,
The engine block of the '91 M5 (3.8 liter) is based on the M30 engine (3.5 liter). I believe
dropping the oil pan is the same...if anything,
sump capacity is higher on the M5 i.e. bigger pan making it harder to get off. Need to check the ETK to see if the pan P/N is the same.
Best Regards,

I have no idea what an M30 engine is, I have a 91 M5. Does anyone know how much harder it might be with my motor?

As Adnan said..its a bear to remove the oil pan..I tried initially to get the pan of my M-30 off by raising the engine..couldn't get the motor up high
enough on my E-32/735il. Bill R has done it this
way on I believe other Bimmer's. You need about
a three inch lift. Mine hit at about 2.5 inches.
I believe the best way is to drop the crossmember.
You still need a cherry picker to restrain the
engine while you drop the crossmember. As far as
checking the pump...the internal clearances of my
pump at 145K still looked good. I replaced it
because I wasn't going back in there any time soon. If you really want to tackle this job,
send me an E-mail with any questions that you may
have...remember the journey well.

James,

Pulling the pan on an M30 is a bear. Ask George Mann as he recently did it and can probably give you very detailed instructions.

Basically, you have to either raise the engine or drop the suspension cross member a couple of inches. Remove the pan and rotate the crank as you go to extract the pan. Not exactly a fun job. But hey, now's your opportunity to replace that leaky sump gasket :-)

It sure sounds to me like you have an oil pump problem, not a canister one.

Regards,
Adnan
