So lately I have been noticing that I am developing a louder and louder noise in the area of the timing chain. I am looking for some helpfull opinions on what you think it might be. I am planning on taking it back to the dealership as soon as I can get the car reflashed back to stock. Personally I think it could be the timing chain, timing chain guide, or a lifter but then again I am not sure. Here is a vid of a cold start and you can tell the car is not happy. Thanks for your help in advance.

Mines making a similar noise but nearly as bad and only on cold starts. I would bet it's the tensioner or the guide.

 

deff timing chain tenioner

 

That makes sense cause it really only makes a noise when it is at a constant rpm or whenever you let off the gas. I want to get this taken care of asap cause I don't want the chain to break and cause the piston to pound the **** out of the valves.

 

yea...do you have any warranty left..cause i think there was a tsb on this awhile back

 

Yes I do, only 5k until I am out of warrenty.

 

Yeah I would bet a dollaar that thats a tensioner issue. do you have any codes? because the chain can actually jump time and set codes when it gets really loose like that.

DO NOT drive far(at all if possible) with it making chain noise like that, these DO pop chains without tensioners. Then youve got bent valves.
