leigh rowland Posted October 19, 2010 Share Posted October 19, 2010 I have just put a 2,5 diesel engine into my series 3. The engine is known to be good but had been standing for some time.I have not fitted the oil cooler. The engine starts quite easily and appears to run well without very much smoke at all.It seems to have plenty of power and pulls happily on the road. However it is literally pumping oil out of any available orifice. It started doing so around the oil filter housing and then the dipstick . It is breathing very heavy through the Oil filler cap and some traces of oil are coming up and back into the air intake. Now it is pushing oil out through the front crankshaft oil seal. There is no other "breather" on the engine save the one through the oil filler cap. Even on the road there is little blue smoke from the exhaust, so I assume the rings are ok.Anyone got any idea what may be the problem??

Leigh Sounds like a worn engine i my books, its dumping compression to the sump hence the oil will be forced trough every opening it can find, unless its over filled with oil! Or maybe a blown head gasket into an oilway. G Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 20, 2010 Share Posted October 20, 2010 Or if it has been standing, rusted bores... Quote Link to comment Share on other sites More sharing options...
Snagger Posted October 20, 2010 Share Posted October 20, 2010 It could be a bad head gasket, but I'd suspect bore corrosion and ring damage from standing or cracked pistons from previous overheating (common on these engines). Pulling the head will allow you to determine which it is. Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted October 20, 2010 Share Posted October 20, 2010 Is the vacuum pump pipe connected to a servo or blanked off? If it is no & no then that is where the problem lies as it will be pumping air into the crankcase. Quote Link to comment Share on other sites More sharing options...
leigh rowland Posted October 25, 2010 Author Share Posted October 25, 2010 Thanks a lot. Will explore the vacuum pump - you may be right Phil. By the way I hail from Rugby (many years ago). Regards, Leigh Quote Link to comment Share on other sites More sharing options...
