injector/wireing harness

early 99 250 7'3 255k, decided it was time to change out the harnesses for my injectors and glow plugs, thought what the heck put in a set of injectors and glow plugs too! Popped #5 out and there was no oil as i would have expected, but found some antifreeze seeping into the injector cup!?! Do i pull the heads and replace the gasket , then cups , or do i have a bigger issue?
Thanks for your thoughts

no need for that bud, but you do however need to replace the cup. Has a crack in it..(common after so many miles). BTW, have you recently changed your coolant to an ELC type fluid? Reason i ask, is because the E99 used a different type of injector cup sealant, that is NOT compatable with ELC. Now that you have an issue, nows a good time to replace them all and change coolants or just replace the suspected bad one, and call it a day.

You'll need a special removal/installer tool for the cup/s. RiffRaff has them along with tool rental.
