Hi i got a motor build about 3k miles and couldnt start it back up about 3k miles. i had some problem with a vtec pressure like at 4th gear a week before this happen. Im assuming its like a oil problem or something. i cleared the code and a week didn't drive it hard or so.
the next week i drove it hard up a hill but oil pressure was constant 60psi seem ok.

Next night couldnt start up managed it to start but rough idle etc?
it started knocking and knocking faster etc. sounds like in the back of the intake manifold block area. i got the block notched and i was thinking could it have cause or a bearing be bad.

Dropped oil pan/ seen glitter like copper acl bearing.

i took apart the motor Eagle h beam rods number 4 seems to not have Endplay unlike the other cylinder rods if i move it flywheel to crank gear sideways. hard to move?

is this the cause of the noise?

i gave my whole bottom end to the machine shop to get it checked and re rebuild new bearings etc?

im sill waiting untill it is done.

Could the con rod #4 with no endplay causing the knock noise like a metal ping knock sound?
