Fuel in Coolant, Cummins TSB170004

[Yauchout]

it worked for mine didn't leak for over 200K miles until I was forced to inframe due to two broken piston rings #5 and #6 like signature said its just a bandage though. i highly suggest if you are going to try it to just purchase the special tool and do it yourself because if you pay the heaps of money a Cummins shop wants and and it doesn't work you were very close to the price of a head. at least that's the case over here in the states
