Hey guys. I just purchased an 05 f150 with the 5.4L Triton. I don't remember hearing the ticking during my 2 test drives, but after signing the papers and parking it in the garage I definitely hear the ticking. Only at idle, goes away at higher engine rpm. I'm still under the 3000mi/60day used car lemon law for NY state. How should I approach this with the dealer?
I just purchased an 06 a few weeks ago as well. The salesman told me that all the 5.4's have a tick due to one of the joints in the exhaust, but it does go away after things get warmed up. Up to you, but I wouldn't worry about it too much.
