well lately i've been noticing this slight tick, and no its not the ls1 piston slap because it doesnt sound like that, i have that and know what it sounds like, instead its like a flapping tick, sounds like its coming from the ignition/ exhaust manifold. I changed the plugs/wires a few weeks ago, maybe something got lose , I will have to check, but the the EGR Gasket was a little damaged (certain pieces are chipped) dont know if this would affect anything

Could have a small exhaust leak.

could be the EVAP selinoid ticking, mine does it when i first start up the car but once shes warmed up its gone.

I'll see tomorrow if it keeps doing it while driving, but I'm thinking its an exhaust leak, it sounds like its coming from under the exhaust manifold.
