I know this has been discussed recently but I can't find the post!
How far on to the guides are the seals meant to go? Are they meant to go on so far that they stop the valve spring seat from moving?? There seems to be about a 1 or 2mm gap between the bottom of the seal to the spring seat on the ones I have done so far. I've banged them down with a socket.
Dunny mate. Gonna get Mr Poole's gen on the matter on Sunday. I am at a loss as to what it is. Getting pretty down about it. If it's serious it's new engine time. I dunno though. By what I've told Gary, he seems to think it's breather issues but so many people are telling me different things at the moment it's mashing my head!
yeah, mine had 1-2mm gap between the end of the seal and the spring platform.
the first time i rebuilt the head that gap had me scratching my head for ages. so i really belted the socket and extension, it went on further but blew the top clean off the seal. that bitch took ages to get off now it was broke, and i had to fish a used one out the bin to use
