Hey guys, I just completed a head gasket job on my 07 GMC LBZ truck and it now has a small tick. It is coming from the drivers side and from the balance rates it shows #6 being out of whack. Now it did not have any ticks or knocks before tear down and I know 100% the valves were adjusted to GM spec. Here is what I am thinking. I used the GM torque value to secure the injector hold downs but I spoke with someone and they claimed the GM spec isn't enough and I should torque them down more. I think compression is being leaked past the injector causing the faint tick and higher balance rate. FWIW I did use new sealing hardware, both oring and copper washer.
Anyone ever hear of this?
