i know it's been out there, but i was following up again this morning, has anyone else found a problem with their 4.7 tapping on the passenger side? ive come across that it could be fuel injector, torque converter bolt bein loose, cam needing adjustment, to it's perfectly normal that most 4.7 do it because of the compression in the cylinder walls...i just think it's odd its louder on the passenger side towards the front of the motor...like maybe a pulley or something???

 

Mine does it only when its cold. Its a broken exhaust manifold stud. taps long enough for the metal to get hot and expand then goes away...usually about 15 seconds...

 

Nah mine does it constantly

 

pull the valve covers off and see if the the lifters are seated correctly.

 

trying to avoid that lol

 

can you make a video of the sound? post it if you can. its probably lifter noise. how many miles on the motor?

 

u cant hear it for a video...it has over 160,000... it's just been doing it a while, no power loss...no codes...im just concerned if it's a problem i wanna fix it, if it is a common 4.7 sound then i'll ignore it...to me it sounds like a lifter too, BUT having SOHC motor, if im not mistaken wont have a lifter...

 

lash adjuster or lifters that are under the rockers.

 

hmmm...i'll have to take it apart here soon

 

i take back what i sad about lifter noise. at 160k+ miles i bet your timing chain has stretched and is slapping around. same thing happened to me when i had to swap a head gasket, the chain stretched a whole link. had to pull the other VC off and adjust that side.
