My TD IP has developed some leaks. It's currently installed on the Fox 1.6na out of necessity but it had been on the shelf for a while so I expected some leaks.
My biggest question is whether to redo the whole pump or only the leaks. It's leaking at the distributor head, shaft seal and cold start advance...which means it has to come off the car.
I have a complete kit so a full reseal could be done...
Also, I can't find the specifics on replacing the distributor head o-ring where it talks about turning the pump to specific location so that the springs etc don't fall out when you back-off the dist head bolts, so if anyone has that link or info lmk.
At any rate I dismantled the whole pump, which was good because the timing advance chamber was loaded with crap.
Now I'm on to the reassembly part but there's one final sticking point....should a person dismantle the distributor head if the valves weren't leaking?
I've never seen a VW with leaky distributor valves and the history of a successful removal of the valves is questionable. What I read is that people end up breaking these when they try and take them apart...after all, they are brass.
