I have a leak that appears to be coming from the large triangular nut in between the injector heads (the circled bits in the photos) and I have a few questions.
1: Where can you buy an adapter to fit over the bizarrely shaped nut?
2: Can the seal behind the nut be safely changed while the pump is still on the car?
Damn you ultra-low sulfur diesel!
YOu can get the seal from a bosch dealer.. AS far as the tool I favved one for scratch... Probably a certain size 12pt socket that could be ground out to work as well.. Chances are good you're probably going to be doing the rest of the seals before long..
I used a 12 pt 24mm socket and ground 6 of the points out. It has worked great many times. That seal is incredibly easy to change on the vehicle. I'd torque the strange nut back on to 60+ ft. lbs.
Excellent! That's just what I was hoping to hear, thanks a ton!
