This is a genuine manufacturer approved replacement part designed for use with lawn mowers/tractors. This gasket provides a seal for the valve cover. Over time it will shrink, become brittle and crack allowing for leaks. At that time it should be replaced. It is made out of composite material and it is sold individually.
Replacing this item you would need a wrench.

Parts Used
I removed the hood on the lawnmower for easy access.
Removed all the bolts securing the valve pan gasket.
Bumped the cover with handle of small hammer.
Cleaned the cover and all the area it mounts to, final cleaning with a little lacquer.
Took a good look at valve cover pan. Discovered that two of the bolt holes were bent in too far from over tightening from a previous install. Laid cover on flat surface and gently tapped the center of bolt holes to make flat.
Then I used 1 perm text (its brown). Small coat on valve area then installed gasket then spread lite coating on gasket. secured to mower snugging bolts.(Not real tight). I let the mower set for two days. (NO LEAKS) The gasket I used is made of cork not rubber.

Cleaning your mower before starting this repair, will help you see any oil leaks after you change the gasket.I removed the valve cover. Cleaned mating surfaces. I put a 1/4 inch bead of black gasket sealer on the valve cover and installed new gasket. Pay attention to the bolt holes. I used one of the bolts to make sure the bolts would go through once cured. Wipe off excess sealant. I let it cure overnight , but read directions on the sealant you use. I then reinstalled the valve cover and torqued the bolts to factory specs. Make sure NOT to over tighten bolts. Make sure the oil is at proper levels and start motor and check for leaks.
