Hello guys, This isn't for me but for a friend of mine. I know its hard to diagnose a rod knock over the internet but I believe my friend's 2k GT has it. The only thing is that it comes and goes which is really odd to me. The car shudders and its doing the knocking thing then it pretends to be just fine then a couple minutes go by and it starts the knocking thing again. I know the 4.6's are very particular about low oil which he has run it low a couple times(light didn't turn on though I never trusted ford idiot lights). I am just curious if there are any other things that it could be that I can check. I just read something on spark plugs which I am gonna check this weekend. More in hope of than acceptance of a rod knock. Thank you for any thoughts or sugguestions.
Kevin
