Hey everybody, first time poster. 14k miles ago I installed Warren 190/30 injectors in stock 2005 ford heads. Everything was great until my studded gaskets let go. I took the opportunity to order KDD ICON heads and have them installed. They reused the 2005(first gen) injector hold downs. The injector seals came from my ford gasket kit. Now, I haven't made it 300 miles without an injector seal burning up. First injector(cyl5) seal burnt up on the test drive after head job, .2 miles. Mechanic was driving it. 200 miles later I was driving and cyl4 seal went. I took the opportunity then to check torque on all the driver side injectors. Now, another 200 ish miles, the girlfriend borrowed the truck the other night and I'm certain it has knocked another seal out but am out of town so cant check it. What is going on here? Do I have the wrong generation hold downs? Are the injector cups not driven completely in by KDD? Are the bolts just backing out? I'm at a loss for why this is happening and how to correct it. Any recommendations(other than "use a torque wrench")? Oh, yeah. There is no oil to blow out of the bolt holes when using new, virgin heads.
