So for the past maybe 2 years ive had a tick/rattle in my motor. It happens only at 1200-1400rpm or so and is gone at idle and higher rpm's.

I was advised to check the guides so I pulled it all apart and checked for broken guides. All was fine. Swapped out for the new style tensioner as well.

I assumed it was a bad lifter since the sound was impossible to track down. It doesn't really sound like it is coming from the timing area at all.

So fast forward to yesterday. I was swapping my valve cover out and noticed the timing chain. Here is what I found. Could this be a source of my noise or is this normal in certain instances?

all lnfs have a tick that come from them and yes it comes from the timing chain

ur tensioner uses oil pressure to tension. so the chain isn't loose cause there isn't full tension on it without the motor running. I had a tick in my motor, it was a worn cam lobe. check ur cam lobes. all of them.

I can't tell from the video,
but it says he has a 2002 chevy Caviler (Next to his name) , or a 2003 Chevy Cavilear (On his profile)

I dont think those use LNFs.

LSJ.... Supercharger is in video.

Also Like stated above the new tensioner is oil pressure operated, compared to the old spring loaded one.

I got a new tensioner a while back and it was spring driven.

I dont know where people keep comming up with the oil ones for the LSJ.


Also watched the video again,
saw the M62 Thanks

My mistake you are right there is a spring that has to be set.

It is spring and maybe oil assisted?

The car is a 03 cavalier with a supercharger setup from the lsj on it.

they do have a spring, but if u look at them they have oil passages in them. so maybe it uses spring but as the engine runs faster it needs the oil preasure to keep tension.

if you turn the motor the slack should be taken up. doubt thats the cause of the tick
