BMW on the other hand uses a gasket for every mating surface of the engine. On the 9000 SAAB recommends Permatex Blue between the oil pan and the block. It does say to use anaerobic sealant between the timing cover and block. I used either Permatex Blue or Orange on both surfaces for all four 9000 I own/owned. They still hold. I did look up what anaerobic means. It means cure in absence of air. I simply do not believe it is a complete vacuum inside the timing cover. You can follow the book if you want. Do not apply more than a 3/32" bead or you'll find it inside the oil pan. Not that it is a big deal or detrimental. People are concerned it may plug up the oil passages. The strands are never big enough to go pass the oil pick-up screen on the oil pump suction in the sump pan. In my first Permatex Blue application on a 94 9000cs I used 3/16" bead. A few strand ended up under the oil pump pickup screen.
