Re: Diesel pump leaking 1.9tdi -help new problem ;(
No worries,
Yeah that rear seal change really is not an in-car change. Even with it standing upright in the workbensch i managed to dislodge a washer and lock the pump up. Difference is you can check it by hand without breaking it when you swing it with the starter.
Had to undo and try again before getting it right the second time. Very fiddly thing so honestly, remove pump, do the seal and refit for anybody that want's to DIY this,
And if you are uncomfortable taking the pump off then really you should not be doing this yourself and I really am not nasty here.
Just an honest opinion trying to save somebody else a lot of money and hassle.

Re: Diesel pump leaking 1.9tdi -help new problem ;(
I think this is why the one how-to video recommended to check the assembly by turning over the engine by hand. (Socket on crankshaft pulley or special holding tool on camshaft pulley.) If the injectors are removed, there is no compression, and it should be relatively easy to feel any resistance. If I were ever to DIY this repair in-car, after having seen all the videos and having read this thread, I would certainly not swing it directly with the starter.

Re: Diesel pump leaking 1.9tdi -help new problem ;(
I promise you - take the pump off is better. There is almost no way that you will stop things from falling incorrectly when you take that distributor section off with the pump in place.
The VW factory manual also clearly states that. Honestly it is a very risky shortcut to take.
Just remove the pump. It is not that difficult to do. Yes you have to set the timing afterwards and make sure you have put the belt on correctly.
It's also quite hard to remove injectors that has been in the motor for a while.
But hey it's people's choice - just know this - I will never agree with that in-situ method , neither does the factory and it is highly risky. When you do it just know that upfront.

Re: Diesel pump leaking 1.9tdi -help new problem ;(
Is it the distributor head seal that's leaking, i.e. between the main body and the square block that feeds the four injector lines? Apparently it's this seal (large Viton O-ring) that mostly springs a leak. I did this repair myself, after sourcing the repair kit from Bosch (about R300) and receiving the relevant section of the workshop manual from Stephan. The other two seals on my pump are still fine. But I have replacements, now that I bought the whole kit.
Like Stephan wrote, this job is best done with the pump out of the engine and standing upright. If you have some experience with repairs like a timing belt replacement (i.e. you can check and adjust engine timing and belt tension), and if you have a decent bench vise for holding the pump in a clean work area, then this repair can be done DIY. I'd be happy to assist you by phone if you decide to go DIY. But unfortunately, I can't help with the actual repair, as my weekends in May are pretty fully booked. Where are you based?
BTW, Bosch part no. for the repair kit is
2 467 010 003

Re: Diesel pump leaking 1.9tdi -help new problem ;(
P.S.: I stripped two heads of the four torx bolts holding the head to the pump. I replaced them with 12.9 Allen cap screws, R5 a piece from a bolt&nut dealer. No problem.
Also, a torque wrench would be good to have, but if you have enough experience, you can work by hand.
Lastly, get some paraffin and a smallish brush, for cleaning the pump externals before you start the actual seal job.
