Re: Befuddled with engine problem
Good points. Both rockers were extremely loose on #6 - As if they were intentionally backed off. The clatter and visual was obvious once the valve cover was off.
#6 was also the cylinder with the old spark plug that had no gap.(see pic above) All the other plugs were gapped at .035 and were burning clean.
Let’s say the cam is bad on #6. Would both lobes go? Seems there is more to this mystery - perhaps the seller’s short term fix to get rid of the truck?
