'86 Golf 1.6NA--leak is coming from under the IP. How can I tell if it's the pump itself or the cold start lever gasket or what?
I'm a novice mechanic but want to learn how to do more on my own. Is replacing the IP too difficult for my limited experience? Advice? Thanks.

If it runs good then the internals are still good so you probly don't need a rebuild, I would say just buy a seal kit off ebay and fix it yourself. Some of the seals are easy to change with the pump on the car and others need the pump took off and they're still perty hard to change. The pump can't leak except through bad seals. good luck!

Indeed. I just got 2 calls this week for old MK1 diesels with leaking injection pumps. Both were good runners until about 3-5 months of running ULSD. The Jetta I tinkered on Saturday was literally pouring diesel out at about 5-8 ounces/minute.

Are there any other places that I can expect a fuel leak because of the ULSD changeover and shrinking seals?

Is this the seal kit that will work for me?
"Rebuild Kit for Bosch VE Diesel Injector Pumps. This will work for 1.5, 1.6L volkswagen injector pumps and will replace all of the major seals that tend to leak after 10 years. If you have a 1.9L pump, non-TDI, the kit will work for you. If you have a TDI pump, the seals won't work for you."

You'll need a Bosch DGK 126, and then you'll have to buy the input shaft separate. There may be a kit that included the input shaft seal, but I think Bosch does not include it in the DGK 126 kit. YOu can buy the seal separately for about $5-10. Call your local Bosch dealer and they'll give you prices.

Personally when I find a leaky pump I hook the feed line up to a bottle of ATF and run the car until the bottle is about empty at various RPMs. Then I let it sit overnight. Next day the leak is usually fixed.
I recommended this to a few people on the boards but have not heard anything back (that I saw anyways)
I'm 2 for 2 and use the cheap canadian tire stuff

some ATF has stuff to swell seals up and stop leaks right?

I think it all has a seal conditioner

Very interesting! Using this technique, how long is it before the leak shows up again? Do you just rev your car up in the driveway, or actually drive it around? I assume most of the ATF gets sent back to the fuel tank, but I guess this isn't a problem. Do you think this would work on my main pump head seal? Any particular ATF you would care to recommend? Thanks.

This sounds interesting, I haven't ordered anything yet so I'd like to give this a try. ATF is automatic transmission fluid? Can you describe this process a little more for me. How do you hook the feed line up to the bottle? I'd like give it a try and see what happens. Thanks.

Well, I tried it last night. I had a pump head seal that was leaking about 2 drips per second. After running a quart of ATF through the pump, and letting it sit overnight, the leak is down to about 1 drip every 3 seconds. I think I might try it again today, and let it go a full 24 hours and then see what I get. It is definately better than it was!

yes auto tranny fluid. Basically take the feed line from the filter off and stick it in a bottle of ATF. I don't drive around because then you can't monitor the level of fluid and you don't really want to run out of fluid. Yes some will go back into the tank, but it's not much of an issue as far as I know. (I'm not an expert by any means).
