    Got the Truck tuned .... Well kinda

    Well, got tot Nelson performance this morning and Allen begins to work his magic. Everything was going good when the the ticking came back. He got the tune solid up to 7psi, after that it started cutting out. Looks like the lifter from hell is back, I just don't get it. Well on the way home I was super pissed so i started really beating on it. It stopped cutting out at 7 and is hitting 10 no problem. Still have the ticking so it looks like i get to pull the heads again. Any ideas what would kill a new lifter that fast.
    Thanks

    What oil are you running? FWIW, Mobil 1 makes my brothers 4.8l tick and Castrol GTX doesn't. Maybe you somehow developed an oil restriction to one of your lifters???

    The tick gets pretty loud, definitely not normal.
    Maybe you cleared the plugs out.

    Since we didn't get to 10psi, be sure the a/f ratio is ok, i'm sure it is.

    Wow, and those are new lifters? Which ones?

    Are you soaking the lifters in oil for a bit before installing them?
