I suspected as much about the o-ring. I used to have a VW fox and the injector seals were kind of a problem with that car too. In that case the injectors were rediculously accessible so the fix was more of an annoyance than a headache. However, in this case the o-ring would get all twisted up because there was a long narrow opening for them to go down before they hit the seal point. Even so they would seal OK until the rubber started to harden up. I never used RTV on them but I did consider it. Recently I found a product that's a bit more heat-resistant than your typical RTV. I can't think of the name off the top of my head but I'll look it up for you. This being said, I don't see why you should not be able to use a sealant but I would recommend being real careful how you apply it. If you got it on the nozzle it would definately give you problems. The only other concern might be the compatibility of the stuff with gasoline but you are probably talking about such a small ammount that leachables may not be a big deal and would probably just burn off anyway.
