hello hopping you guys can help to find out what is happening. i just replace belt tensioner pulley and delete the upper idler pulley (i had to do that because alloy threads were scrubbed, also replace for smaller belt)

the sound is harder at idle and when rev up the ticking noise is not noticeable

any idea?

 

Belt flopping any? Almost sounds as if the tensioner is "jumping"

 

The tensioner looks good when rev up and there is no squealing on the belt

 

The bearings could be shot!

 

Even if the ticking gone up to 1600 RPMS?

 

Could be your timing tensioner/guides

 

Check your spark plugs. I had a ticking noise on my lightning and blew out a loosw plug. My friend just told me about a ticking noise yesterday on there mustang. And the plug blew out later that day.

 

Update, the noise has increased ( not too much) I just remember that the sound just stared the day that I replaced the stock mufflers whit the SLP LM2, should in relate that?

no smoke, MPG are normal, no power loss. the car runs perfect, someone has any idea?

 

The noise comes from driver valve cover, and is harder than timing cover ( I used a stethoscope)

 

Ditto same deal with my 97 GT, it hasn't cased any mechanical problems though. I think the plastic valve cover has gotten loose with age

 

Do have any plan to stop the noise?

 

It's weird when I put my hand on the valve cover it stops making the noise. I had a friend who is a mechanic look at it and he said its fine, just the plastic cover warping with age. It has been doing this for a couple years now with no issue besides the noise at idle

 

Well I thing my issue is not as easy yours, mine obviously comes from inside, I hope was as easy as yours

 

The sohc 4.6 is known to have a noisy drivetrain. Mine makes a slight ticking noise, its a 2000 gt.

 

How many miles?

 

95k. Car runs fine. Just drivetrain noise.

 

Is as hard noise as mine?

 

Just watched the video, no not that loud.

 

I was considering to change the 5W30 for a 10W30 to see if that would help to reduce the noise considering that the oil change is soon

Do you guys think that helps?!

 

Honestly, probably not, but its worth a shot.

5W is probably a little thin to use in the summer, but won't hurt anything.
