e30m3 0 Posted April 6, 2007 (edited) I've just had my car running and when i reved it the oil came back up through the oil filler Doh Anyone got any ideas as to what could be the problem? I assume the oil system is pressurising some how. Edited April 6, 2007 by e30m3 Share this post Link to post Share on other sites
Guest silver 1600 Posted April 6, 2007 Yeah sounds like you are getting excessive crank case pressure mate. Are all the breather pipes in good nick and clear of blockages? Share this post Link to post Share on other sites
e30m3 0 Posted April 6, 2007 Yeh I think the hoses are fine, they all caome off my old engine which ran ok other than burning a fair bit of oil. I've just done a compression test and is come up as follows 150, 195, 185, 175. Could the problem be caused by a leaking head gasket on piston ring? or does anyone have any other suggestions Share this post Link to post Share on other sites

Could the problem be caused by a leaking head gasket on piston ring? or does anyone have any other suggestions I would say that the cylinder with 150 may have a problem as it is lower than the other 3. What i would do now is get a little engine oil in a squirty oil can and just put a little oil in on top of the piston in the cylinder that is down on compression. Then do the compression test again if you get a higher reading than before this points towards rings Im afraid . Edited April 6, 2007 by silver 1600 Share this post Link to post Share on other sites
