I have searched the internet and found some information relating to having Diesel Fuel getting into the coolant and this seems to be the injector sleeves. Does anyone know how to narrow down what side, and/or what sleeve is causing the problem? What is the fix and about what do you think the dealer will charge to fix? Any recommendations for a dealer to repair in Michigan? The vehicle is a 2000 Excursion.

 

As far as I know, the only way to identify which injector cup is leaking is to remove the injectors and look. Best bet would be to have them all replaced. Dunno what theat would cost, I'd guess around $400 since the tech will pull the heads to remove the cups.

 

i am pretty sure i have heard they pressurize each rail with air and what ever side leaks down they go from there. good luck. are you still under warranty?

 

No Warranty. This one is out of our pocket. What stinks is we have had a few of these 7.3 engines and our oldest is a 96 with 230,000 miles with no problems like this. Here we have the 2000 with just over 100,000 miles and the engine needs to be torn apart.
