nu jeg skal til at samle motoren skal jeg lige høre om
i smøre pakningerne med noget, olie, fedt, flydende pakning,
wd40 eller lign? eller montere i dem bare tøre?

If you are going to be a good mechanic you've got to put away childish things. One of these things is using gasket cement everywhere. Gaskets are made to expand just a little when oil hits them. This makes a good, oil tight seal. If your sealing surfaces are smooth and you have a new gasket, you simply do not need gasket cement. A real sign of an amateur is lots of slobbery gasket cement. So do you put the gasket on dry ? No, you use plain ordinary wheel bearing grease. I use grease on all new gaskets except the ones that come from the factory with a special coating already put on. The grease serves several functions.
Is there a time to use gasket cement ? Yes indeed. If there is a gouge or nick in the sealing surface, it will need to be filled in gasket cement. Sometimes no gasket is called for and the two parts are sealed with a gasket cement. There are many types out there. Get several that are sold in your area and see which one you like. I prefer the non hardening kind and I don't like any of the silicon seal types. The silicon seal types tend to ball up inside the engine and come loose plugging the oil screens and choking off the oil flow... not good. I really like YamaBond #4. It's a gray gooey cement used to join the crankcase halves of Yamaha 2/strokes. It doesn't ball up. Any excess inside the engine seems to flatten out and sticks to the side of the crankcases. I use it for any metal to metal sealing jobs where there is no gasket. I use it even if another sealant is called for because it works so well. Works good with gaskets too. You can get it from Yamaha. I don't use the silicon seal stuff at all. Not any brand... too many baaad experiences !

- It will hold the gasket in place as you put the two pieces together.
- It allows the gasket to move around a bit as you put in the screws.
- It starts the swelling process that the oil will finish.
- It allows you to disassemble things easily if an error is made and allows you to reuse the same gasket after you fix that error. Not that I ever make errors... well... I did once. I thought I had made an error, turned out I hadn't !
- It allows easy disassembly in the dim, dark future.
