Small hole in head at bottom of valve cover bolt!

Who in their right mind would say that???? Lol!
Like I said I would have done it a little differently but have never had an issue with JBW and gasoline...must be something to their claim.
I have a 3 wheeler that has had a blob on the bottom of the gas tank for about 10 yrs and still no leak.
Not saying JBW is the be all to end all but to each his own.

It's GREAT in its element. But I have to admit, I've seen it let go in a gasoline environment. Was it applied wrong? Maybe, but it still let go. And contrary, like you, I've seen it hold up on gas tanks. Who da heck knows?
