My IP on my 92 NA Golf is leaking at the point where the distributor head joins the pump body.
I was wondering if anyone's had luck with changing the seal without removing the pump or will a crapload of parts fall outta the pump if i try this?
Is there anything i should be careful of when i do this?
Anyone know a good source for the seals in the Mississauga/Toronto area (the Bosch warehouse is 2 minutes away from me, do they sell 'em)
Thanks

People have done it and there is a guide to doing it somewhere.
However i would always take the pump off the car in order to change seals.

Yes it is possible and if done correctly there is absolutely no risk of damage, but if done incorrectly it can wreck the pump. I've posted links quite a few times. Search is your friend. DON'T USE THE CRUSTY CRANK OR DIESELGEEK METHODS!! They don't safeguard against ruining the pump.
Follow Adrew's details exactly and it will work ! I tried to follow his, but as I loosened the 4 cap screws, I let them come out a bit too far and was interrupted by the dinner bell. When I came back out 30 minutes later, the head springs had pushed the head a bit too far off the body and the shaft came out of alignment, so I had to remove the IP completely. Its now waiting a rebuild as I had several spares that were much easier to swap the seals on the bench - this time following his details w/o delays.

i did it once and ruined my pump. had to take it most of the way apart to fix the pump head that i snapped.

Gonna try libbybapa's method posted here h**p://www.vwdieselparts.com/forum/viewtopic.php?t=5311 and see how it goes.
What's the difference between seal kit DGK-121 or DGK-126?

oh hell no, i didnt know crap about pumps, took the pump head out, re sealed it, then when i tried putting it back together, i broke the pump head. then after i broke that, the rollers fell out of the cage. so then i took it off, reinstalled the rollers and put a new pump head on it. still works...

You didn't keep constant pressure on the plunger, did you?
:-D I had until dinner time, then it looked like the cast iron head was fused to the aluminum body, not realizing the O-ring was all that was holding it together - thus keeping the constant pressure until it let go. I understood to not even try to put it back together at that point w/o a full tear-down.

Went to Sharma Diesel in Mississauga to get a seal kit. The guy there told me no need for the kit if all i'm gonna do is replace the o-ring. He gave me the o-ring for free!!! so i figured i'd give him some recognition. BTW he had this smug smirk on his face, and said he doesn't know of anyone who has done the seal replacement on-car successfully without trashing the IP. Soooooooo the gauntlet has been dropped 8) Gonna try and tackle it later this week. Thank God its biking season. At least i can get to work on the ol Honda ;D

Clean the outside of your pump well, follow Andrew's instructions slowly and carefully, and then take the old o-ring back to your supplier and tell him to hang it on *his* wall. ;)

y. its not that much work to remove it
-
just pick up the drivers side of the car and set it on the passenger side. then none of the rollers will fall out of the pump.. lmfao...

FWIW, I bought a distributor head o-ring from Giles and he too was doubtful that I could do the reseal successfully with the pump in-car. Followed Andrew's instructions and it went off without a hitch.

Thread returns from dead for great success.
Looks like some of my fuel return geysers need a bit of work.
