Has anyone ever had a valve cover bolt disappear? Looking around my wheeler when washing after a 100 mile ride in Black River Falls, WI and noticed a little oil on engine and low and behold one of the above mentioned bolts must've worked itself out after I had adjusted valves.

 

I have seen several come out of the 500-425 motors, I keep a stash of them in my shop and check all the machines I service every time I see them, should be able to get them at dealer and just replace it.

 

Make sure and clean out the bolt hole real good before installing a new bolt.
Might be debris in the bottom of the hole that can cause You grief,jus sayin.........

 

Bet ya its the front bolt on the drivers side! Seems like this is the only one I've ever encountered missing! Quite a few over the years! OPT
