So, I'm sure this dead horse has been repeated flogged, but in all my searching, I've yet to get a definitve answer.
This is what I'm asking:
Is the Bosch IDI injection pump rebuild kit:
DGK 126
1 467 010 059
made of Viton or just some generic rubber.
I got bent over a few months ago by GreaseWorks.org for $50 for one of their 'Viton IP Rebuild kits'. The box came, and it was in a standard Bosch box. It lacked the "DGK 126" designation, but it had the 1 467 010 059 part number on it, which is apparently the same number as the DGK kit.
I was a bit perturbed when I discovered that the kit did NOT include the main shaft seal. Nonetheless, I sent the pump out to be resealed (red---rider ebay name). He did a great job and included the mainshaft seal for an extra $5. The pump went back on the car, and went out the door. I sold the car on ebay for $4000 (not too bad). That was several months ago: haen't heard back since.
I've now got another car on my hands. I sold the car to a friend about a month and a half ago. It's a 1991 Jetta EcoDiesel (some of you may have seen my posts about concerns over the operating temps). Anyway, she brought the car back last week for some fuel consumption issues. She claimed poor fuel economy (37-39 MPG), but barely put 1000 miles on the car. So, I fixed a few minor leaks (leaking injector, return line, end plug etc), and am now addressing the fuel gauge which only reads 3/4 tank when you fill it to the brim. I figured that would solve it, and I'd drive it for a week to get a good reading on the MPG, since I only put about 200 miles on it before I sold it.
Anyhoo, as I'm cheking the timing on the IP, I notice that it's leaking from the cold-start lever (yes: the dreaded). It didn't leak a drop when I sold it to her, but now ALL the local gas stations are selling the ULSD, so that may be the culprit.
No biggie, I found out I can just buy the seal kit for the cold-start lever (068-198-052A available from your local dealer or WorldImpex.com: thanks TurboDieselTech). But here's what I'm thinking: the girl is a bit "hippie" minded and likes the idea of BioDiesel. That's cool and all, but I'm afraid that even if I fix the current leak, it's gonna start leaking in other spots down the road (distributor head, accelerator lever). In fact, I think that she's already running B20 in the car right now (at least it smells that way). So, I'm thinking a permanent solution might be best: a complete reseal of the pump. The thing is, if she wants to continue running biodiesel, and perhaps in even higher concentrations, then she'll really want to go with all Vition.
BUT, to be honest, I don't really believe that the kit that GreaseWorks.org sells is ANY different from the standard DGK-126 kit that I can get anywhere for like $10 (especially since the picture that they have is of an actual DGK 125 kit).
I've read in posts elsewhere, that GreaseWorks can only confirm that it's Viton by "word of their dealer." If that's the case, then I can see no reason to buy from them when it costs 5X as much as anywhere else, and there is little to no factual confirmation that it is indeed Viton. Even if it were, GreaseWorks never seems to have them in stock, and it takes 1-3 weeks to get them. I want this car out of my yard this week!
Any thoughts/comments/etc from those with knowledge/experiece with the various kits, or the GreaseWorks "VITON" kit specifically would be immensly appreciated.
