Slant Valve Seals

No you don't have to remove the head. I really wouldn't worry about the seal that is pushed up.

yeah that was the least of my worries....1 bent push rod.....2 loose rocker shaft bolts.......um er and 3 loose head bolts........when I say loose i mean you could turn them with a socket and your fingers... and the push rod was so bent it was rubbing the drool tube.

I just pushed it back down with a small flat head screw driver and re torqued some bolts and forgot about it.. :)
