    LB7: LB7 injector sleeve o-rings

    Just making this clear that as long as you loctite, torque right and let sit over night, even if the sleeves pull out you don't have to replace o rings? Thanks

    LB7: LB7 injector sleeve o-rings

    It doesn't have a breakdown of part numbers. I was worried if they're even the right thing. Do the orange o rings look right in that link? Cause I don't even know what all those other little ones are for.

    LB7: LB7 injector sleeve o-rings

    Hey guys. Finally finishing my passenger injectors:D Had a few questions about the injector cup o rings. When I did the drivers side the sleeves pulled out and I replaced o rings. Didn't know if u had to do this or not but I like to. Now of course no dealership within 150 miles has o rings so...

    Thanks Thank you. I'm just starting to get worried after attempting to do injectors, my first time attempting it as a young kid I just got scared that I'd have to take apart that tricky drivers aide again due to a faulty injector. Once I do the other side I will keep you guys updated.

    injectors I'm aware that all 8 injectors need replaced. Like I said in the first few post was that I was waiting to get my paycheck this week to buy 4 more which I did. It is hard for some 40 year olds to fork out money like that here and there let alone a 17 year old. I will be installing them...

    How do you go about cutting injectors out? I checked the balance rates again here they are.

    Haven't checked compression. It only smokes at idle and clears out when I pull out. Haven't gotten to recheck passenger side. How do I put a picture up on here?

    Hey guys I just replaced my drivers side injectors due to bad rates on #6. Going to do passenger side soon but rates seemed within range. What could this smoke be at idle? Still injectors. Head gaskets are not the issue either...

    Lb7 blue smoke...

    Okay. Is there any way to differ between injector cups and head gaskets? It only loses a little bit of antifreeze and never gets over 210° even while pulling a trailer. Just don't want to do the head gaskets if I don't have to. Plan in selling the truck and just wanna fix this blue smoke issue...

    Lb7 blue smoke...

    Hey guys. My Lb7 just turned over 227,000 the other day. I have been noticing though that the last few days after idling for a few minutes in a drive thru or something like that my truck starts to smoke blue. Then when I pull out it dumps blue smoke for probably 10 seconds then clears up. It...

    LB7: Lb7 Blown Turbo?

    Didn't get to try to start it yet. I wasn't going to make the trip until I had some things in my head of what to look for. I was going to go tonight and tell you guys what it does. Any kind of checklist I can go over prior to starting and then diagnosing if it doesn't start? Thanks guys for all...
