D8h valve lfter guide very worn

About the only recovery I can think of is to bush the block back to original size.

Have you seen that done? Was it successfull?

No, I have not actually seen it done but I don't see why it couldn't be successfull.

Yes this type of repair is successful. We have done them before. Cat make a sleeve to do the job. They even had tooling to repair them in chassis. Good luck in finding a dealer that would have it though. Last one We did the block was stripped for a rebuild and had a machine shop do the repair.
I will try and find the part number if you want it.
Where is Eddy when you need him.LOL . I'm sure he would have come across this before. LJ

thanks for the info.much appreciated. i found it hard to believe that a block would be discarded because of this.
A part number would be a big help. Finding someone with the tools and the knowledge will be the hard part.
Is the sleeve pressed in or is it welded?

What little I recall about the procedure is that the bushings were press fit.

The part number for the repair sleeve in question is a 5P6513.

Check the cam lobes on the associated cylinder.

Good Luck.

Anybody got information on the tooling and process involved????

There is a special instruction sheet associated with this repair but my copy is very poor. The tool group used is a 5P6512.
