Re: Injector cups and tools!!
I had the same problem a month ago. I found out that the o-rings that separate the fuel area from the coolant area were worn. All 8 of them. I thought that was strange, but they all wore the same. I would definitely pull all 8 injectors and replace the o-rings. My cups were looking great. Probably didn't need to replace them the mechanic said. I had the heads re-worked too. The heads were milled on both the "bottom" and the exhaust side.
I know it is a huge expense, but I would also recommend to have the heads pulled off and gone through. If you are getting fuel in your coolant like I was, which wasn't bad or a lot I should say, you can almost guarantee that the o-rings are going bad on all injectors.
Hope it is under warranty. Mine weren't and I about sold the truck because of the price tag!
