Dan, The spring on the bad valve is not compressed as much because the valve is stripped and the keeper is closer to the end of the valve allowing it to expand more than the others. I'll take another spring off and make sure they are the same height, but I suspect they are when relaxed.
Bill, If the keepers didn't touch at both sides I'm sure they do now, with the valve stem being stripped. I'll take a closer look at the keepers and take some pics, right not the head is at my new friend's house. (anyone with as many VWs as he has is a friend to me) Dean On Wed, Apr 17, 2013 at 1:10 PM, Dan Moy <sole...@gmail.com> wrote: > There is a clue in what you said, if there where swivel feet, than it is > really important that the push rods are cut to the appropriate length to > insure that there is no binding, in addition to installing > the appropriate shims. > > Also what does this mean: "The spring wasn't as compressed as the others" > the springs should all be the same height? > > Regards, > Dan > > > On Wed, Apr 17, 2013 at 12:58 PM, Dean Johnson > <dean.g.johns...@gmail.com>wrote: > >> I also want to know why.
