The short story:
I recently replaced the top cover seal, the quantity adjuster seal and the Viton seal. Visual inspection reveals no leaking what-so-ever. Yet, after 10 minutes of driving, the diesel smell is so bad my eyes will water up.
The long story:
I recently purchase a 2002 Jetta TDI that had been run exclusively on bio diesel for the past 4 years. The owner warned me that if I switched to regular diesel, the injector pump would most likely leak. Hence I prepared myself, read this post (http://forums.tdiclub.com/showthread.php?t=287336) and bought both a Bosch kit and a Viton seal.
Sure enough, at about 1000 miles, it started to leak from the top and/or bottom seal. I quickly replaced two of the seals (not the Viton), adjusted IQ and was on the road again. As far as I could tell, no more leaks. Alas, not all was well. I drove the Jetta to South Lake Tahoe on a VERY cold weekend (10 degrees overnight) and lo and behold, the next day I had a leak from the right side of the pump. A BIG leak. It was not dripping, it was flowing.
So I towed it home (AAA rules) and set to work on it. I replaced the seal with a Viton seal as many threads here recommend that. Note that even though I did not have to remove the top cover or the adjuster, I did anyhow to avoid spilling too much diesel. After IQ adjustment, the car seemed fine once again. (Could this have damaged the top and bottom seals? I doubt it.)
At first I thought the diesel smell was just a side effect of having had diesel spilling for a while. I was hoping it would go away soon enough. It has been over two weeks (about 400 miles) yet the smell remains and I am fairly sure that it gets worse the longer I drive it.
I've not spent too much time under the hood since the Viton replacement, but a quick peak after driving it does not reveal any wet spots. (I do however have to clean the engine, will do that this weekend.)
So my questions are:
1. Are there other seals I may have to replace (do to switching from bio to regular diesel)?
2. Or is it normal for the smell to remain for such prolonged periods of time.
3. Aside from a visual inspection, are there other test I can run.
Extra notes:

In lieu of purchasing the Metalnerd Socket, I just took a dremmel to the head and turned it into a regular screwdriver head. Took some skill to take it off, but now I can readily take off and put it back on.
