My 2006 V8 EB started the annoying engine ticking noise at start up about 3-4 months ago or ~65k miles. It definetly sounds like lifters or an exhaust leak mainly coming from the passenger side wheel well. It increases with engine RPM and lasts until the engine is warm (a few minutes). I have had the truck since new and have had every conceivable maintanence done on the truck using Motorcraft parts. I read some old posts and it looks like it could be a cracked manifold, Lash Lifters or VCT? The truck is under Premier Care so I brought it in to my Local Ford dealer, let them keep it over night and they could not figure out what was causing the noise. They said the Factory told them it was normal. I called the Factory to complain and the representative basically told me I should not call and complain about a dealer and that the noise was normal. I told him I have owned the truck since new and know every sound the truck makes and that this was not a normal noise! Anyway, it has been a few months since then and it is still ticking and seems to be lasting longer now. My question is, should I take it back to that dealer or try another one? Should I get Ford Corporate back involved? Anyone with similar noises who have had it fixed at a Ford Dealer and can offer advice? I love this truck and want to keep it for a long time but this sucks! Thank you all.
