well i decided to pull the injectors out the other day so i could see if i had another cracked nozzle.i have one that the copper washer is nowhere to be found.below the bottom oring is all carboned up and looks melted.besides needing a whole new injector what other damage should i expect?think it cracked the injector cup?i wasnt loseing coolant oroil,no mixing of coolant and oil or growing oil in the pan from fuel and oil mixing.just always had a skip i couldnt track down to 1 cylinder.it always moved.come up with cylinder 2&6 bad,run the test 10 minutes later it would say 2,3,6,8 were bad.then it started running out of power and loseing fuel pressure when i parked it.so my suspicion of an injector sticking open when it got hot was confirmed.:D

Clean the cup good and make sure the surface where the copper seal washer should meet with has no pits in it. Stuff it with an injector and go.
