    I just replaced the head and gasket. Now my truck has a small tick in it. Even the tack jumps when giving it fuel. :biggrin_25511: I had one of the injectors replaced and still doing it.

    All the time. It gets worse as you let it sit an idle. Could I need injectors? I just put one in after a shop ran a test.

    Could be injector and could also be a faulty head with a very slight wear pattern near one of the injectors.

    Just thinking out loud here. Where did you get the work done? Was the overhead done correctly? Did you get the block cut?

    Did you get the block resurfaced or did they just put it back together. With out cutting the block ( resurfaced) the head gasket don't seem to last to long before it blows again. Could be a week, could be a year. You might also have a cracked spring. That'll make a tick sound or even make it sound like an exhaust leak. Hope this helps

    I believe he is talking about a cracked/bad valvespring. What kind of warranty did you get? and was it doing this before the work was done?
