i have a supercharged 04 tl, a while back i started hearing a ticking noise coming off the front head (by the radiator), i just went to get lunch n came back, did a quick first gear pull n now im hearing a loud clucking noise but it is not constant.... it comes and goes, i can hear it for a second when i hit the gas n then it goes away. im afraid i did more than just bent a valve, i think i might have cracked the the piston in between the rings. (ring island?)

what do u guys think? and what could be my best bet at the moment. also it kinda stumbles when i hit the gas sometimes and at idle it wants to shut off but it doesnt....

 

Make a sound video if you can as various engine components have vastly different sounds as well as oscillations.

 

Is this noise worse with RPM or with throttle? Any different from cold to hot? Any bubbles or oil in the radiator? Any water in the engine oil or under the oil fill cap? Any loss of coolant?

Does it have a miss at idle that goes away when you go under boost? Have you done anything to suppress detonation? The supercharger as it's sold is destined to blow the engine. Adding methanol injection will insure a long trouble free life.
