    Set them to spec. To tight decreases valve cooling time, to loose increases hammering and can lead to roller skid on rockers.

    Then they’d be looking like the roller dog machine at the Pilot, Lol. Not good. What about rebuilding jakes? Nothing to the kits, as I recall. Real cheap parts. I’ve never seen any how to instructions. Don’t guess they have step by step instructions with the kits. Mine are original work good. One had a bent feeler guage looking bar. I bent it by hand to match tension of the others. Didn’t affect operation before or after. Anything special to Rebuilding them? Or is it just replacing some springs, o rings, etc,?

    Nothing to hard about rebuilding them. Genuine Jacobs kits always came with pictured instructions. You can download manuals from Jacobs website.Service Literature | Jacobs Vehicle Systems

    gonna get truck today. they claim issue stopped even after test drive. But im so skeptical if they really test drove it. the guy was like oh we are too busy for test drive. until i spoke to manager. im hoping they are being honest. 1 injector labor parts disgnosis 2800$ like come on wtf. if its done ok fine. but if its same issue. no way im returning. theyll bankrupt me at that point.

    $2550+$2800, total $5350.00 I was close. Still not bad, you knew the risk when you reused the injectors. Reminds Me, maybe I should go ahead replace oil pump and rockers. Only things I didn’t do. Oh well, sometimes it goes that way. Glad it’s fixed.
