So! To start I have 2009 with hemi . had a Lifter seize and grind down my cam shaft on cylinder 5. So I replaced all lifters and cam shaft with oem parts
. I messed up the timing of the cam and crank putting it back together. i put it back together exactly the way it came off. Got codes for wrong timing and misfires. So took it apart again and re set timing. no codes for timing but still misfire. So did compression test and had a bad head gasket. Replaced that and now good compression but still misfire in cylinders 6,4,7. Got code for fuel injector circuit for cylinder 6. so that pretty much covers that. Did all spark tests you can think of and problem persists on all 3 bad cylinders. Also swapped fuel injectors and problem persists. Reset PCM, problem persists. Did Leak down test. No valves are leaking exhaust or intake.
It turns out i did not put MDS lifters in cylinder 1,4,6,7.
This explains the truck running like absolute garbage.
I installed MOPAR Part # 53022263AF (Camshaft) but i haven't been able to confirm if this is and mds cam, I'm almost positive it is correct but if someone could confirm that would be great.
Also can you explain why regular lifters just wont work, not that i wanna use them but just to fulfill my curiosity.
