Was speaking to a mate yesterday with a e39 520i, now it is using lots of oil, blue smoke out the exhaust, the works, he was coming home the other night and it went down on to 5 cylinders, went to change plugs and plug number 3 was oily, done a compression test and number 3 was down to 110 psi where as the rest are up at 180psi. he was wondering what could be wrong with it! rings? etc

Now i think its not to bad, i think that the head gasket is away between the oil way and cylinder 3 causing the oil to go into the bore, oil up the plug and its blowing oil out the exhaust causing the smoke! does this sound possible?

probably the oil scraper ring cloged

has the car been serviced at the right intervals with the corect oil grade??
