    Has been knocking now a few days. Sounds like a rod bearing but everything I read says injectors. Is this common?

    Crack the lines to see which one is bad , then if really want to move to a different cyl to see if the noise follows.

    Injector body and fuel line will typically be very hot if it is sticking open allowing exhaust gases backing to the injector causing a knock. Can even melt the return line cap.

    I've had nothing but excellent results from Conestoga Diesel Injection.

    A bad injector sticking open will also cause pressure built up in fuel tank.

    Russ, aka Type4, is also a good source for new injectors, he’s in Oregon, south of Portland.

    So this would be why my gas cap is so tight. Thank you

    Injectors I got from Wes have been hammering away flawlessly for good while now, I highly recommend his injectors.

    After I put them in and timed the truck it began starting within the first bump of the starter, he built them right
