It's terminal. Holes in the body, holes in the frame, everything on it's last leg. I had to make a deal with the inspection station last year promising not to take it back. I have two rust free busses that will be letting this one live on, and the car won't be junked but is becoming seasonal housing for WOOFers. I would love to fix it if it's clutch hydraulics. What's a good way to test it? -Craig On Sun, Nov 6, 2011 at 9:54 PM, Scott Daniel - Turbovans < scottdaniel@turbovans.com> wrote: > Hi Craig.. > first you sound like you want to get to the bottom of this mystery, > and fix it, > then you say if you do pull trans .. > you don't want to put it back in. > > Additonally .. > I have no idea how good/bad this machine of your is ..... > personally, I think Vanagons are world class vehicles, and overall .. > the best VW model ever built.. > and I could list 25 other reasonst they are valuable, unique, > non-replaceble etc. > I never part any out .. > unless htey are rusted badly ............crunched, a not-so-great model, > etc. > > I strongly doin't believe in wasting good things in order to get a good > part or two, or more parking space, or whatever. > > The 85 stock vanagon I last worked on that had a bad pilot bearing .. > was distinctly intermittant, and actually ... > you can put one together with no pilot brg at all and it'll still work. > We don't know what your pilot brg is like... > but in the one I'm referring to, there was just rusty dust left of the > pilot brg rollers. > The warning to presever the input shaft by not continuing to drive still > stands. > > I've made one good one out of two cars before .. > many times... > and through the left over one away .. > BUT ...........they were not Vangaons. > > name any vehicle that is so easy to work on, such a great size, comes with > a huge world-wide family of affecianado's , has endless suppliers for, > drives very sporty when set up right .. > and you can sleep in it, and haul tons of stuff .. > and comes in many configurations ... > and about 10 other things I'm not thinking of right now. > They are extremely worth saving. > > I use the really bad ones to mine minor odd parts off to save other > vanagons. > I have one ..........an 85 with the interior totally burnt up .. > that van has been a great source of all kinds of oddball parts over the > years.. > plus it's storage. > I realize not everyone has a place where they can keep ....whatever.....15 > + vanagons. > > Hyducalics ...less apt to be intermitant, but it's stil possible. > One of my sayings is that no amout of emails or talking can substitue, > really, for hands-on dissasembly and inspection. > But then I seriously enjoy working on them.
