engine knock on startup
i have a 2007 expedition i bought new it has a 100K warrenty on it.
it stared to make a knock on startup that has gotten progressevly worse over time. the dealer installed new timing chanis and this did not help. it sounds like a rod or heavy detonation. it does not do it all he time. the dealer is blowing me off and saying he does not hear it. i have seen posts about cam phasers and piston slap and that if you complain enough they will replac the engine. need help
