Double knock
only really heard at idle after the car has been driven for a while(good and warm) was thinking loose flywheel bolts,but wouldn't it also be heard when engine cooler?? good oil pressure,per dash gauge,everything else seems fine,and not a spark knock,the knock sensor not picking it up,what do ya'll think I should check next?

well lets see he doesnt have a torque converter so thats not it.
does it happen while accelerating or just as you come off the gas or while starting and stoping?

first heard it
while in the drive thru line,pulled over to parking spot,and tried to hear it under the car,just sounded like a ticking,but get back in the car and it sounds like a double knocking sound,as you rev it up,the sound kind of goes away as far as hearing it,when first started,you don't hear it at all,just after being driven,and like stop at a redlight or something,funny it seems alot louder inside the car than outside????
