Gasket,​​ Valve Cover 20 041 13-S

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.

Remove cover and clean surfaces. Apply a very thin coat of form a gasket cement to all surfaces and reinstall new gasket and valve pan cover. do not over tighten bolts for this will cause distortion of metal cover and gasket.

Remove top cowling to access the valve cover gasket. remove cover and old gasket. Clean both surfaces oil new gasket . install new gasket and tighten all bolts uniformly. run engine for 10 minutes then tighten bolts another turn.

Removed valve cover, replaced gasket, reinstalled valve cover. checked for leaks. (none). Then I removed the air cleaner cover, removed the old air cleaner and placed the new one in, then installed the air clean cover back on

Great price on part! I am not a mechanic. But this was easy

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.

Look up instructions on "how to" ..... then follow instructions for each part used in maintenance.
