So I currently have a dilemma that has me lost. 2010 H/C/I/E, pullies, ported blower, ZL1 lid, forged rods and pistons. I hear a noise in the top end and take it apart to inspect. I pull the blower belt and notice the noise is still there. I pull valve covers and I see nothing out of the ordinary, pushrods are straight, springs are good ( BTR .660 duals with ti retainers ). I see on the build sheet it has LS7 lifters so I dive in and throw a new set of lifters in. Pushrods currently are 7.400 BTR units. I get the car back together and the noise is still present. I have no misfires, perfect oil pressure, zero performance issues with the car. I just have this God forsaken noise everyone swears is a lifter. I have fresh oil with less than 100 miles. I double and triple checked exhaust bolts and bands, tried pulling plug wires tonsee of there is a tone chnage. Nothing.
People say they're noisey, people say the engine materials with thin wall long tubes makes the noise worse. I have the noise local to one spot and will add pictures and videos and specs. Where the F do I stand. I am to the point of pulling the engine.
Forged rods and pistons
King bearings
Millings HV oil pump
Vengence VRPD-2 231/239 .617/.624 118LSA
Btr 660 dual spring kit
7.400 pushrods
2.55 upper
9.1 lower
BTR trunion upgrade
FIC1050 injectors ( pump gas )
Ported LS3 heads
Ported blower
ZL1 lid
Killer chiller
New Ear 4.5" intake
The red.circle represents the only place I can hear an auditable noise with a scope.
