GEN 1 2010 5.4 engine tick (video)

[Hockster]

I have the "Silver" protection plan. Includes the manifold, but nothing in any of the plans about injectors. And just to be clear, this is not normal, correct? It's been to the dealer about 5 times for service and they've never said anything. I have a feeling they might give me the "normal for this engine/model" line.

Do you know if the truck ever had a injector cleaning. The dealer offers a pretty good cleansing treatment. Not sure about cost but over time things get dirty. All vehicles have that tick some are louder than others. The evaporation system has a solenoid that can cause the same tick but it sounds louder. Does it change with rpm?

Mine went from a light tick in the summer, to a loud tick when the weather got cold along with a loss of HP & fuel mileage.

New manifold, zero tick and everything back to normal.

No injector cleanings that I know of. Tick speeds up with increase in rpm. I just went outside and did the ol' screwdriver stethoscope trick. Sound is definitely in the fuel rail. I unplugged each injector separately but no change. I put the screwdriver to that 2" cylinder looking thing on the top of the passenger side fuel rail, and it seemed to be loudest there.

Manifold tick is different than injector tick. Plus it would go away for the most part as you drive the truck, letting the manifold get hot unless its very severe crack.

True. When mine was a light tick it did go away when the engine got hot.
