There was nothing wrong with the HLA's. That's why it's been so frustrating. Dealers have rebuilt these engines with all new rockers and HLA's for all cylinders, and the tick is still there. The only thing that could cause an HLA to to tick like that, while still being in normal working condition, is a lack of oil pressure. That's pretty much the only other possibility I know of.I think pulling the ignition coil plug is part of Ford's normal diagnostic testing. What does the Ford diagnostic procedure say it could be based on what the observed resulting noises are when the ignition coil is disabled?
So did this guy get his HLAs replaced if that was the conclusion ... and if so what was the outcome of replacing them? Or did Ford just say "hey, it's normal" and send him on his way after charging him for a diagnosis?
Keep in mind, the very slight intermittent tick from an HLA with just slightly less oil pressure than needed, is nothing like an actual failed HLA. When an HLA completely fails, and does not inflate at all, the noise is really bad. However, if it is inflated, but with oil pressure a little low to maintain tight forceful contact, it may open just a thousandths of an inch to give that tiny little tick that otherwise wouldn't be there.
