It does leak a little from the rear but the loss is so small there is no point fixing it. The car has certainly had a hard life! It is on its second turbo and gearbox. The turbo was replaced some 4-5 yrs ago and the car is now on 145K miles (As you may recall I replaced cam chain). BTW I always try and use synthetic oil. The most agreable one I have used is 10W-40 Castrol GTX, currently 15 from Halfords for 6 litres (BTW Castrol is a little confusing with their labeling. The 15W GTX said it was a standard cheap oil, whereas the 10W-40 said it was synthetic for advanced engines). Fully synthetic Valvoline is the next to go in. > anything when you use them. Quite the contrary, in fact - > Slick 50 has been sued, Prolong has been questioned, and > I'll bet that if more people had heard of Militec 1 and it > was more popular, they'd get sued or questioned too. BTW I once witnessed a very embarresed sales rep trying to sell this crap once(not slick 50 some other stuff). He did that thing where they smear this super oil improver onto a ball bearing and then measure how much pressure you can put on it before it seizes against a driven mains bearing. He showed how 10W oil etc. doesn't take alot of effort to over come, and how their 10 a bottle improver can take huge loadings. My brothers boss came out (30 yrs experience in car dealing/fixing) and slapped some duckams axle grease on the thing. You should have seen the guys face when no amount of force would cause the thing to seize! > Besides, I've taken apart enough Saab engines over the past > few years to know that wear is not a problem.

Usually people replace or rebuild engines that have nothing intrinsically wrong with them. BTW he has a lock up full of engines that no one wants.
