I don't get it, something does not smell right. If you threw the timing belt, then that means you have the V6 engine, which is not known to have the sludge problem, AFAIK. If you do have the 2.3L 4 cylinder engine, which has been suffering the oil sludge problem, then you have a timing chain, not a belt. > > Have had my car dealer serviced at the correct intervals for all but > one service when I went 3,000 kms over. > SAAB(GM) knocked me back on compensation for the new engine because of > this. I'd fight it. One oil change 3,000 k past due would not have caused this problem on a properly designed engine. They are just looking for reasons to avoid paying-out on warranty issues that are obviously their responsibility. > > Motto: > Don't believe the service intervals from the dealer - they should be > halved for oil changes especially with city cars. > Find a specialist SAAB mechanic who know the car. Funny, but that has always been the case (reduced change intervals for frequent short trips). I don't see how having a service interval reminder on the dashboard would negate that. -Fred W
