My car makes a ticking sound from the head it seems. I just did a valve adjustment everything looks fine and straight everythings with in spec double checked it, I also have a new BC valvetrain, ticking went away.... but it comes back after i drive the car and it goes thru a couple heat cycles. I have the modifry ect with my AEM and it seems to come on like clock work 2nd heat cycle at 205 or 4 bars. It does not matter how I drive the car, it makes the sound at idle and stays at the same pitch thru out the power band. The car does not make the sound when its cold.

 

There is a thread somewhere about the TCT, under hood forums I think. I've replaced mine 2 times already. Both symptoms, like a buzzing noise or baseball card in the bicycles spokes noise.
The sound would occur after the car has warmed up, no noise when its cold. Also more pronounced at low rpms or low speed, also upon deceleration when coming to a stop or light the sound is more pronounced. The sound would go away if I put the car in neutral.

 

My car makes the sound in neutral I posted this tread because I read all the TCT treads and no one seemed to have these symptoms

 

You guys dont need to replace the TCT's.. Just sandblast the worm gear inside it and re assemble, re pin, install and then unpin after its in.

 

^ Yep.... I've had it replaced 2 times under warranty.... stupid design.

 

Nice thanks for the info I read on that but wasnt sure how reliable it was.

 

well it still makes noise however everytime I turn my crank pulley tighten with a 19mm the sound instantly goes away any ideas?
