A mechanics stethoscope from a autoparts store for 15-20 bucks and u can hear alot closer on where exact point of sound is coming from.
Is the whole car vibrating when it is parked?
Do you have 6 spd or auto?
You are using only premium gas for the higher compression?
Like I said, no lifters. I just looked at the pictures I took when I had my valve train disassembled. Those are not lifters. Lifters make noise because they are usually hydraulic and they lose the ability to maintain their hydraulic pressure and then there is excessive clearance, hence a rattle.
