My 2010 Mustang GT 4.6L automatic with 97k miles on it has a noise coming from the drivers side valve cover.
The noise sounds to me like all of the other typical cam phaser noises; a ticking sound about once per engine revolution - getting faster when the engine is accelerated but not louder.
Because of the usual failures of the VVT system, I thought I'd replace some parts that normally go out on those things:
Replaced: Driver and passenger side Cam Timing Phasers, Driver and passenger side VVT Solenoids, Both timing chains, crank sprocket, and all plastic timing guides and tensioners, All spark plugs.
It still has the same noise. I probably should have went ahead and taken the heads off, but didn't.
The VVT system while driving still seems to 'pulsate' and causes the engine to ping at times. No engine codes are being thrown.
Engine oil and filters were changed and the correct viscosity oil and Motorcraft filter is used.
Could the oil pressure just not be high enough? Should I have replaced the oil pump too?
Or is it just time to take the heads off? I did not check compression though I probably should have - and checked the oil pressure? Or did a valve possibly get burned?
