Shawn Wright : you are in a good situation ---thanks to being able to post pictures
like you do.
A drillmotor and those old valves can be cleaned in no time. ----Then run them
real slow and se if they are straigt.. Then post pictures and we can all get in on the action.
As usual on mechanical engine stuff I agree with Loren and James Hansen. BUT do
remember all the flyboys out there. When it comes to sodium valves ? ---they got
loads of information.
I have missgivings with your end goal ----- that is a lot of weight to move with so little
an engine. If I did it I would go for the 4 speed tranney from a 1980 four door Rabbit.
a GC tranney. . Remember VW diesels are HIGH speed diesels. ----
I do have experience with sodium cooled valves ---and after 1000 hours of hard service ?
in aircooled AC engine ? ---they look like NEW.
About the HONING job ? looks great ------ there are two types of honing jobs.
Deglazing and fitting pistons after a rebore. Do not confuse the two.
My sin as far as honing goes ? I put on too fine of a finish. By luck they all worked out.
Talking about those bearings on the intermediate shaft ? ---I do NOT like the looks.
Check things out real good to find out what went wrong.
Green stripe ? ---that one still gives me troubles. --------- somebody knows what
it indicates ? --right ?.
I think Chuck Carnohan has a GEENIE ? if you both post the serial numbers ---maybe just maybe
I can solve the mystery. Germans are notorious for keeping track of parts -----
The way I remember it , the exhaust valve in the TDs are a special alloy and coated.
NOT like NA valves.
So at least get the turbo valves --non sodium.
