task Posted March 9, 2010 Share Posted March 9, 2010 With the start of spring just around the corner I decided to drag the Series 3 out of hibernation and kick her into life. Upon doing so it decided to spit oil out the gasket between the oil filter and the remote housing. This was about a month ago in some bitterly cold weather so I put it down to over-revved (poor choke setup) and too cold oil. Pushed the car back into the garage and went inside so I could warm up and feel my hands again. Fast forward to this week and I finally found some time to work on the poor thing. I replaced the oil filter and filled her back up with oil, turned her over and she fired up but sounded really rough. Oil pressure light didn't go out. I have since then replaced the oil pressure switch and removed the dizzy to manually run the oil pump with a drill. Oil flows nicely round the oil filter circuit but I'm unsure if this is oiling the engine. I have removed a rocker cover and can't really make out any oil but I perhaps haven't given it enough time. I'm going back outside now to see if manual pump operation will make the oil pressure light go out and run the drill for a bit longer, see if I can make out any oil at the top of the engine. Failing this I really have no idea what can have gone wrong, never encoutered an issue like this before :/ Suggestion are very much welcomed!

Bull Bar Cowboy Posted March 9, 2010 Share Posted March 9, 2010 Oil pressure relief valve maybe stuck a little open ………….not uncommon. It will take while with the drill to fill the filter and build pressure. Yes, oil pressure light should go out when spinning the pump with a drill.

Aragorn Posted March 9, 2010 Share Posted March 9, 2010 You should always prime the filter with oil before installing it too! Stops the pump having quite so much work to do on first start after the filter change. Quote Link to comment Share on other sites More sharing options...
task Posted March 9, 2010 Author Share Posted March 9, 2010 cheers guys, my primary reason for worry was the venting of oil from the original filter. I did indeed prime the new filter before firing the engine up. Going to venture back out tomorrow and attempt more diagnostics. I wasn't sure if the oil pressure light would go out given the use of the remote oil filter, I'm guessing it will. I also assume if it's running oil through the filter then it's also running through the engine? Quote Link to comment Share on other sites More sharing options...
