Whenever I pull into my garage and turn off my car, I hear all these damn noises. What the hell is that!? It's coming from underneath... sounds like pinging.. Not like an engine knock, but... I don't even know... Can someone tell me what that is?

 

Thats normal, it's just the noises from the built up heat evaquating from the engine bay, or something like that. Now that were on the subject my 95 max always made this weird noise coming from the gas take when the car was off. It would go on for hours and hours. I always figured it was some sort of pressure release valve thingy for the gas tank, but my I30 does not do it....Hmm?

 

Well all the clinkety clink noise is the OE Y pipe expanding/contracting. An aftermarket Y pipe does seem to be quieter in this regard. As for the fuel pressure bleeding off, I have this problem too. I either A) ignore it or B) open the fuel tank thing to bleed the pressure and it goes away.

 

Nothing like piece of mind thanks for the info
