SIR E30 68 Report post Posted October 8, 2008 (edited) Hey everyone, So my E30 (M20B25) had a slight oil leak.. always has, never worried me too much cause it wasnt big. Then it started getting bigger, until tonight I found a huge puddle on the floor of the garage! Turns out oil is leaking through the oil sensor in the side of the block (according to my Bentley manual its the oil pressure sensor). Im replacing the sensor tomorrow. Is there anything I need to do or know before I go rip sh*t and bust and pull everything apart? Just want to make sure I do things properly. Cheers in advance!

Jason Simple enough - undo & replace, Can use a thin ring spanner (cant remember size off hand. I put thread tape or thread sealer on new thread as I replace.
