    Lb7 lower than normal oil pressure

    Hello. I have an issue with my lb7. What i have is an 01 gmc sierra 2500. Heres the history. Few months ago i pulled the engine and installed front and rear seal, head gaskets, injectors and sealed everything up and set valves. Did it by the number. Eveything has been fine until today. 20 psi at...

    Replaced injectors. Knocking

    Wow i assumed it was like all the other gas engines ive built. I didnt know #1 was on the passenger side. I never looked into it. So yes it was number 2.

    Replaced injectors. Knocking

    Runs perfect. No more rattle knocking sounds. It was a crappy injector. The lower valve cover bolt near firewall is a true pita. Ive got some pics of the tools i made to help with a injector job. The upper valve cover slide hammer pops it off in about 10 seconds

    Replaced injectors. Knocking

    Hey guys i made a fuel rail block off fitting out of an old injector line. I started with number one and it immediately quit making noise when i road tested it. Im putting it back together now with another injector and hope thats it. If this injector is good and no rod bearing wrist pin issues...

    I checked yesterday fluids. No oil in water or vice versa no fuel in oil. No contaminated fluids anywhere. Also the thing is perfectly drivable. I just hate the sound. So yall are saying those balance rates are good?

    also the nearest dealer that MIGHT be worth a shit is 75 miles and i just can't afford to go there. get paid by my boss to do the work. it doesn't matter to me how long it takes to cap off 1 injector at a time. i don't have time to leave my truck for days or even weeks with the idiots around...

    these are balance rates from a genesis scan tool. I don't really know what I'm looking at so any information will be appreciated. also yes orielys sells them reman by borg warner. the Only reason I put them in is because my boss charged them there. i suggested against it. now we are both paying...

    Ok thanks. If the o-ring is bad will i be getting blow-by? Because i have hardly none. Can you tell me if you think i will damage an injector by cutting off fuel to it?

    Replaced injectors. Knocking

    Wow thanks for the amazing reply with the info about what it would do to the injectors if i cap one of them off. No i havent run it without the belt yet, again what is the reasoning for removing the belt? Im just curious. Also yes i had one stuck in the cup. At least 2 had o-rings that were...

    Crap i didnt see page 2. Thanks guys. No its not exhaust leak i checked. This engine has zero leaks. Its 51 here this morning and when the truck cools off overnight it doesnt do it until the engine warms up. Im 99% sure its not mechanical valve train noise either. The damn engine idles and runs...

    Replaced injectors. Knocking

    Well that is the next thing i suspect. I loosened all rocker adjustment screws and set at .012 however i followed some instructions on here but couldnt get tdc. I didnt know it was a mark on balancer. So i ran them all once like suggested. Then twice more the way i would a solid lift gas engine...

    I have ppe hot+2 et or something like that. It will show live data on injectorsz displayed in ms. (milliseconds) i guess? 7 are 3.5 to 4 at idle and 1 is 1.5 to 2.5 is this data useful?
