    Valve drop :(

    Makes sense, it’s my first diesel so I guess I didn’t notice the signs. These motors are tanks lol it seemed to run pretty strong since I got other than when my injectors failed.

    Valve drop :(

    I was used to all my street bikes and dirt bike valves tightening but I guess that’s also from the high rpms and valve seats wearing pretty quick.

    Valve drop :(

    I’ve had the truck a little over 3 years. I never had the valves adjusted... any chance clearance could have became to tight and opened the valve a little more than it should have and got kissed by the piston? Or more like punched lol

    Valve drop :(

    Could have been but the fuel issues were leaking injectors even after the new ones were installed then got replaced under warrant and the engine overheating ended up being just a bad ect sensor. Engine always ran pretty smooth other than that. At this point though I agree it could have been some...

    Valve drop :(

    I’m assuming there is, I wasn’t able to immediately shut it down being on the parkway so it probably ran all through the motor. I’m pulling the motor from the truck this weekend.

    Valve drop :(

    Coming home from work the other day and merging onto the parkway I got on it a little and immediately heard a pop then knock knock knock knock. Pulled over and had the truck towed home. Pulled the heads and found cylinder one dropped a valve and basically destroyed the piston and cylinder walls...

    LB7: smoke issue

    From what I was told by the shop they are supposed to be pretty reliable. They also come with a 2 year unlimited mile warranty.

    A shop called Jersey Deisel Performance. It's right across the street from XDP, they told me they used Dtech injectors.

    LB7: smoke issue

    Just checked my balance rates this morning. When the truck is cold injector 1 is -7 and injector 6 is -5 all other are within spec. Once the truck is warm injector 1 goes to -3 and injector 6 goes to -3.5. Just had all 8 injectors replaced a few months ago.

    LB7: smoke issue

    So back in December my truck would smoke at idle pretty good and once I took off from idling it would leave a trail of white/dark blue smoke. I got all 8 injectors done and since then the truck does not smoke at all while idling or while taking off from idling. After all that I got an egr code...

    LB7: Engine overheating after injectors

    Brought my 04 lb7 to a reputable shop around me to have all 8 injectors done. Ended up paying $4300 to have them all replaced and they also replaced the thermostats while they had the housing cover off. Next day driving to work the truck started overheating I shut it down once it hit 248. I...

    LB7: Injector issues

    Also the truck idled fine and drove fine. It did not have that lope at idle that I see most lb7s with bad injectors do. It just starts smoking after idling for a while.

    LB7: Injector issues

    Possibly but I don't think so. My fuel pressure stays right with commanded fuel pressure at idle. I did notice under WOT I lose fuel pressure and had this problem before swapping injectors I made a thread about it. The fuel pressure dropping under WOT went away out of nowhere. Also I heard a...

    LB7: Injector issues

    Hey guys so my 04 lb7 started smoking when sitting at idle for more than 10 minutes and when I would take off white smoke would blow out pretty good for a short period of time until it seemed to clear up only to start smoking again once sitting at idle for more then 10 minutes. All injector...

    LB7: Fuel issues WOT

    Trans seems okay. It has always shifted smooth and quite. I am running a super chips 90hp tune. Truck idles smelling a little rich but idles fine, cruises fine and starts fine.

    LB7: Fuel issues WOT

    Okay so I've recently been having a problem with my lb7 at WOT. Now I can get on it merging on the highway full throttle and it will pull real hard and other times I will get on it and the truck will rev up and go nowhere. Now I mean it is a major difference in power. Recently got an edge...

    LB7: 04 lb7 Fan runs 100% of the time

    I did not know that they didn't have a relay... I definitely didn't flatten out the fins so I guess i'll look into the fan clutch. Thanks:thumb:

    LB7: 04 lb7 Fan runs 100% of the time

    I've searched through tons of threads on this issue and I cant seem to find the same exact problem as me. My 04 northeast emissions lb7 fan runs all the time from the second I turn the key to when I shut it off, it doesn't matter how cold it is. I've read about cleaning the cooling fins but I've...
