Ok I have the rattle/ticking/knocking noise and cannot figure it out. Its extremely loud, gotten worser over time. From idle to about 2500RPM, the noise is there but after 2500RPM its very VERY faint, and just seems to stop. Noise seems to be coming from the front of the motor. Would the TCT noise go away after a certain RPM? Could it be that the guides are worn? I do NOT track my car, motor has about 33k mi (AP1). Oil level is fine, btw.

Any help would be greatly appreciated. This is my DD and Im kinda paranoid to drive it!

i would fix/replace the TCT and go from there.

 

^yea, that wouldve been my first step. but money is slow comin in right now. so i was just wanting to get more input on what it could be, just incase ya know. because ive changed it out once already about 15k mi ago.

 

Does the rattle stop after a little while of idle?
When my tct was worn down, there was a rattle sound lasting for a few seconds after I started the engine. It got worse for e few months before I replaced it. It stopped after reving it a little, so it could sound like it's your tct that needs replacement

 

no the noise never goes away, just after about 2500RPM's...

maybe ill have to order a TCT ...so no second thoughts on if it COULD be worn guides? ive had a couple people hear it in person and suggested it could be the guides ill try and find my camera and post a quick vid of it, soon.

 

you can sandblast the worm gear to save money from buying a new tct

 

What does this mean?

 

that would fix the part that is failing inside the TCT.

i personally do not know how to do this, but there are threads that discuss it. try a search.

 

How much does it cost to replace the timing chain tensioner?

 

The part is about $120. Takes about 10 min to install...but I'm sure many shops will charge for more time.
