I am putting together my '01 Viggen engine after balancing chain failure and see that oil pan and timing cover use liquid gaskets instead of traditional paper ones. The local dealer recommends anaerobic sealant for oil pan ($45) and ultra gray for timing chain cover. Anybody has any advice on where to get it - dealer, after market, etc.

This is the traditional utilititarian way SAAB is handling engine part mating surfaces and it works. 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.
Thank you very much for the tip. I found the whole product line at

Use Loctite 518 it is anaerobic and is oil soluble, so it doesn't leave bits floating round the engine.

I think the key is not to apply too much of any of that stuff so it does not get behind the oil pan or timing cover, etc. With Loctite the oil soluble thing scares me. There will be plenty of oil in the oil pan... I got the permatex black tube for $5 at Pepboys instead of tube for ~$45 at the Saab dealer.

The anarobic bit sets in the joint, it is only the excess that squeezes out that dissoves in the oil, so it doesn't block up anything.
Hello all,
VERY little of the liquid gasket stuff is enough..!
Suppose you do a continuous line of 1 mm diameter, and the seam after mounting is 0.1 mm thick, you get a seal-width of around ( (3.14 / 4) *
1^2 ) / 0.1 = 7.5 mm wide... Thats more than enough already for most applications. Just make sure there is a continuous "line" along the surface you need to seal.Richard
