Hi to all, just thought I would pass along a fix I found worked for my 90 e30 with a drip from the oil plug. I drained the oil into a clean pan & cleaned the plug area good to see what was causing the drip.
As I looked closer I found a small V shaped nick on the edge of the flat area where the washer fits thus the leak. So I thought about it for awhile and dug into my O ring selection and found the right fit put in on and put the oil back in & drove it awhile and then let it sit and Wa La no oil leaking at all. I guess sometimes the easy cheap way works Lol.
