My friend has offered to help me do some work on my car, but i'm having trouble deciding what we should do. I had (i think its gone) a massive oil leak through the oil canister gasket of my non-vanos m50, but we replaced the gasket, and it appears to have gone away. i purchased an oil pan gasket, in case that didn't solve the problem, but now that the leak appears to have disappeared, do you all think that i should do the oil pan gasket? it is either that or change my transmission fluid filter and put helicoils in some of the stripped out bolt holes. i have a mild vacuum leak from somewhere, and after seeing that there is an issue with the m50 sucking in air, causing tick/ping-- through the oil pump pickup gasket, i am conflicted as to which big job i should get done. (we) are both curious to see how the bottom of the motor is doing at this mileage. is a vacuum leak through an oil pan gasket a somewhat common thing? i feel bad because if i were to do the oil pan gasket, i would reuse the oil pump (unless it were obviously eaten out). i don't want my decision to come down to a coin flip, or possibly a "mickey mouse built a house" using somebody's birth age. thanks.

fyi, the stripped bolts are causing a mild tranny leak. i didn't strip them out, a shop did.

pretty juicy oil pan leak if air could be drawn past it it through the case into the intake.

bump for anyone that knows anything about this tsb or the seperate issue. IIRC winfred had once said something about an e36 w/ vacuum leak through the pan, and i know that dick schneiders had gotten the air suck TSB fix applied to one of his e34s.
