water jacket gasket question

[Artjo]

I just want to be sure on this. When installing the cylinder cover and gasket do I use a sealant or put the gasket on dry. Thanks.

What do you mean by cylinder cover? Head gasket?

Re: water jacket gasket question

This engine does not have a head. Its the plate that the plugs screw into. My manual refers to it as the cylinder cover. I am told the gasket behind it is the water jacket gasket. I am replacing it and need to know how.

Re: water jacket gasket question

If the spark plugs screw into it, it is essentially the head, no matter what the book calls it. It usually is a black cardboard type gasket, and it has metal rings where the cylinders holes are, and sometimes other metal around the edge. Do not use any sealer on this gasket. It compresses when you torque it down, and be sure to follow the torqueing sequence which should be in you book. Also, this gasket is a one time use gasket b/c it compresses. Hope this helps.

The gasket is black but not metal anywhere. Looks just like the old one though. Does anybody else agree with kev. I also have another question. What do I use to clean the surfaces before putting the gasket and cover on.

Re: water jacket gasket question

I am still 99% positive that it is a head gasket, but on the older engines, they might be made different. Permatex makes a gasket remover, but be carefull not to get in the water jackets or cylinders. Some really fine grit sandpaper, 1000 or so and a putty knife have always worked good for me. GL

Re: water jacket gasket question

This motor DOES NOT HAVE A HEAD GASKET it is a water cover gasket!!!!!! . If surfaces are flat a thin smear of any gasket cement will do the trick . Torque the screw to 80 inch lbs.
