I recently posted a link about engine knocking and many people asked me to get a sound clip, well i did a tad better and got a video, you can find it here and tell me what you think is the noise source.

bad timing chain tensioner

 

rod bearing?
my engine has this kind noise. only can be heard from lower passanger side wheel.

It cant be the tensioner , if i disable the middle cylinder in front, it gets worse. I tried this with all cylinders, only the middle one makes the noise . I disabled them by unhooking the fuel injector clip, you can see me put it back on in the video.

 

Sounds just like my noisy timing chain and a few other 3.0's ive heard.

 

Could also be noisy fuel injectors.

 

There is a specific clunking , you can hear clearly in the vid not tapping or anything, you can clearly hear it when i back off a tad

That's definitely coming from the bottom end. Bad tensioners clack, not knock. I stand by my original UOA suggestion.

 

if its the tensioner then why when i diable the injector is it louder ? in the middle cylinder ?/

 

We're guessing here, we don't know what it is. Like I stated earlier, my 240k DE sounds like that. UOA UOA UOA UOA UOA UOA UOA

 

and whats a uoa gona prove ? clean or dirty oil ?

More than you know, obviously.

 

Persistence won't make you any less wrong...

 

I hear the noise now, the clunk is distinct if you listen for it.

 

Ok, so say if i install the new tensioner and i still have the noise, then what???//

 

You need more common sense or better comprehensive reading skills.

 

then you start a new thread

 

heh....
