    Injector

    Is there a way to tell a bad injector with HP? I've developed a ticking and i'm not sure if it's an injector or a lifter. I've only got 7000 miles on a build.
    thanks

    Don't know about checking injectors with HPT but I've but I've used a temp gun on the heads to find inconsistent temps.

    I have a fresh build and the ticking was very light. My oil viscosity was too thin. I changed the oil and the ticking is gone and my idle oil pressure is up.

    Typically is a short term fuel trim swinging about 25% +/-
