Lifter Ticking

[kodi101]

Has anyone heard what sounds like a lifter ticking when starting their Explorer after sitting for a period of time? Yours ticks until you you increase the RPMs then it goes away and doesn't come back until after the vehicle has sat for a period of time.

I heard the same thing. The service guy at the dealer claims its just the fuel injectors firing.

I have the same ticking on my 2003 mustang and I would like to know what it is. It really is annoying...

I think this is due to the water thin 5W20 oil we are required to use.

Probably fuel injectors. Flex's do it and I think it is the same engine.

lifters are hydraulic so, they have spring pressure and oil pressure, when cold soaked they can discharge, and when initially started you hear a lifter noise. since its only spring pressure.

I have this same noise and had it confirmed it's the cam phasers prevelant on all 3.5 and 3.7 engines. I'm told it's harmless, however it is annoying.
