Re: 3sge burning LOTS of oil!	Wed, 03 August 2005 12:31

unfortunately, the series of 3sge's in the st162 has had problems where oil is pushed back into the intake system, and is burnt through the car. hence, the excess oil consumption! I found out the very shocked way, when, driving at about 200kmph, the car suddenly bellowed smoke out the exhaust! I thought i blew the engine, but it was all good, compression was all goo too, so i thought the air pipe was loose causing a lean mix. but when the car went on the dyno, it happened again and finally, some 6 months later, we (tuner and myself) think we have found the cause. oil pressure in the sump is very high, and when driven, causes oil to be pushed up the engine and eventually exit through the only place it has! the blow-by system which leads into the intake manifold, which then burns the oil! I'm in the process of getting a solution, and if this is similar to what you guys have experienced, i'll let you know how it all works out. when it first happened, the tuner thought the motor blew aswell, but the compression check came back fine and the spark plugs never looked better! so it was another problem, currently, the solution is to make a breather system for the sump! hopefully, this will fix the problem!
