Richie-Van-GTi 70 2 Cars Posted June 27, 2007 I was just about to change the stem seals on my xu10j4r but on removal of one it looks totally different to the replacements, the one that came off looks like the shim under the spring, the seal and a small sleeve over the valve guide are all one piece, the new ones I got are like any others ive seen from the pug range. can someone please check if there are any variations please and if so what the part number is.
