I KNOW IT HAVE BEEN ASK A 1,000 TIMES BUT IF I BUY NEW CAM PHASERS WILL THE SOUND GO AWAY. AND WHY DO SOME TRUCKS MAKE THE SOUND AND SOME DON'T WITH THE SAME MOTOR. WHATS THE BEST SIZE OIL U GUYS RECOMMEND?

 

If the cam phasers are what's causing your noise then yes new ones will fix the problem. The cam phaser problem was mostly with the 04-05 F150's so the truck's you hear with a quiet cam phaser either has had their's replaced or the original ones haven't worn out. The best oil to run is 5w-20 which is what the manufacturers recommend.

 

ive had new cam phasers put in sounds came back in 10k miles but isnt as loud

 

thanks guys

 

Mine were replaced at 20K miles and they're making a little more noise then they did when they were initially replaced. It was very quiet immediately following the fix.

 

I have not found a good explanation of what causes the problem, or how to slow or prevent it.

 

Ford recommends Motorcraft 5w20 synthetic blend, which is precisely why I use it.

Cam phasers make noise. When they do make noise they do not damage the engine. Ford dealers will gladly change out your noisy cam phasers to pacify your ears, it is an expensive job.

 

I think he is asking which oil to use to prevent the cam phaser problem.

 

I already answered that.

 

just replaced both of the cam phasers, its super quiet now. Different viscosity oil won't make the noise go away. I experimented before replacing mine.

 

Are you saying that those who have a problem with the cam phasers are those who did not use Motorcraft 5w20 synthetic blend? That they could have prevented the problem with Motorcraft 5w20 synthetic blend, or that the phasers would have lasted longer with Motorcraft 5w20 synthetic blend?

 

I dont think he is saying any of the above. The OP asked two questions, and he answered both.

 

Well then that would be my bad because I thought the two questions were related to each other.

 

I WATCH THE VIDEOS AND MINE DON'T SOUND BAD JUST NOISE AS HELL. I TOOK IT 2 THE DEALERSHIP AND THE SAID MY PHASER SOUND GOOD.THEIR JUST LOUDER THE OTHERS.

 

Well there you go.

BTW, your caps lock is on.
