Cam phaser question

Cam phasers ford f150 2010

Hey got a ford 150 2010 xtr. I get a rattle in engine area when I go through like a drive through. It only happens from time to time. Sometimes if I coming to park but only low idle.

Replaced the cam sensors didn’t do anything. Assume it’s the phasers ? How soon should I replace ? Thanks


Have about 93000 km on it. Seams to do this clutter every so often not on a regular basis. Maybe 2 times a week
It’s never in start up either though

 

Oil change schedule is very important on VVT (variable valve timing) engines.
You might consider an oil and filter change with the recommended oil and see what happens..

 

You could try a thicker oil, 10w-40.In the long run you will need new phasers.

 

Are you using a quality 5W20 synthetic oil ?
