I have a mack with aset motor
In may 2023 I had inframe
1 week after inframe had code for egr valve. Took back they replaced egr valve 2200. I kept getting egr codes off and on I have had rough running issues . And an imbalance I've replaced eup's, Inj's. Flywheel, damper. In 2024 I noticed oil pressure lower than normal. So one time egr code came up I took oil line off egr started truck and it took 20-30 sec. For oil to come out and not a quick flow, so I scheduled to go in shop. But before I could get in the shop I lost #4 lifters .
When shop diagnostics oil issue they found #1&3 top main bearings installed in wrong place. I am trying to find out i oil issue on accessory
Side caused the lifters to go bad
They replaced cam, lifters oil pump, oil cooler rods & mains
Also when i showed the bearings to mack dealer they said when infram they did noy clean new bearings or the caps due to wear spots
Will this affect Any other componets all help is appreciated
