SimonT Posted April 16, 2009 Share Posted April 16, 2009 I have tried to research this as much as i can before posting up another oil leak thread but i cant seem to find an answer! I have a reasonable amount of oil leaking from the passenger side and its creating a mini puddle on my cross member and then finding its way to the floor, however the oil filter seal has been changed and the filter is on tight and no leakage is coming from there! The sandwich plate on the oil cooler has also been recently changed so i know its not leaking from there! Can anyone please shed any light of what else on that side of the engine could cause the leak i have? Could the infamous FMS cause this as i have read quite alot about this over the past 15 minutes and it doesnt sound good but i thought that would be coming from the front of the engine not the side but im stumped?? Any help would be really appreciated!! Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 16, 2009 Share Posted April 16, 2009 Steam clean + ramp + fluorescent dye in oil + running with a UV lamp shining on the underside of the engine = ANSWER You may well see the leak without the dye and UV lamp, but it makes it a hell of a lot easier.

Andy Blyth Posted April 16, 2009 Share Posted April 16, 2009 I had an oil pressure sensor start leaking back at Christmas. I was losing about a litre of oil every week. It's located at the front of the block behind the aircon compressor. It costs about £20 for a new sensor (which has been re-designed from the original) and about 2 - 3 hours to replace if you take your time.

Chris Wilson Posted April 16, 2009 Share Posted April 16, 2009 Yes, OP switch is a likely source of a big leak on the LH side of the engine near the front. Quote Link to comment Share on other sites More sharing options...

SimonT Posted April 22, 2009 Author Share Posted April 22, 2009 Had my car finally looked at today and it is found to have 2 leaks! One is the front main crank seal and the other is the oil cooler! Apparently these are sealed units and have to be replaced although ive read on here its normally where the pipe comes out of the cooler that has got covered in muck and perished?? Any advice or knowledge on this would be great?! Quote Link to comment Share on other sites More sharing options...
pistonbroke Posted April 22, 2009 Share Posted April 22, 2009 Not sure about the oil cooler bud, but make sure they pull the crank pulley off properly when they replace the front main. I've heard many a horror story where the crank pulley has been butchered by muppets blasting it with blowtorches to get it off. The result of which means the thing will fly when you least want it too. Quote Link to comment Share on other sites More sharing options...
