I brought my 2006 F150 Lariat (130k miles) to the Ford mechanic because it sounds like a diesel truck. After replacing the coil packs, performing a tune up, replacing an exhaust manifold, and changing the oil, he now believes that I may have clogged oil ports as a result of using Jiffy Lube filters, and informed me that I need a new motor which costs $6200 plus tax. Does this seem right? I am not a mechanic nor know much about these types of things, but isn't there some type of solvent I can run through the engine to clear the potentially clogged oil ports? Thank you in advance.

if it is a low end knock, you need to pull the motor and rebuild it. If it is a ping/detonation knock, you have a similar problem as mine, however, no one has replied. If it knocks at idle and not under acceleration. Change the motor

Thanks for the reply. After additional research, I have decided to use sea foam with the hopes that it might clean the oil ports / galleys, then change the oil / filter - I will report back soon.

Seafoam in the oil...shutter. I don't know where you saw to use that. Here's some more info on the phasers/ticking. Read the TSB in the first link.
