I have had my 2004 stillen supercharged infiniti g35 for about 2 years now and about 8 months ago, my engine started having a kind of ticking noise, engine still runs strong and no check engine light. I just reached 90k miles on the engine. The ticking noise is loudest when the engine is cold and i first start it up, but when its warm the sound goes away while idle. Once i start driving it comes back and the more gas i give it, the faster the ticking noise sounds. video will be posted shortly

 

 

hmm to me it sounds like a valve lifter tick.

 

x2. definitely.

 

let me know when you wanna sell that supercharger
