I have a 2013 RAM 1500 with 5.7 Hemi and started getting a P0301 code. I suspected cam and lifters but a new mechanic (mechanic 1) I used said it was the PCM because it was not sending signal to the injector on Cyl 1. After having it replaced which didn't fix the problem, he admitted to mis diagnosing saying the PCM is supposed to stop sending signal when it sees the misfire. He said he would repair the truck and subtract the $1200 I paid the dealership for the PCM.
When torn he found a cam lobe at cyl 1 worn to nothing. He replaced the heads, lifters and cam but in doing so, it was not timed correctly which after running for 30 seconds it shut down and they found all intake valves bent. They replaced the valves, put it back together but when doing so, shorted a fuse between the alternator and fuse box. Once that happened, they got tons of new codes from transmission to ABS to all over the place. They blamed the dealerships new PCM so brought it back, the dealership put in a new PCM. According to the mechanic, this cleared up the codes.
I was then given back my truck, paid the mechanic and drove off only to find a new CEL with a misfire on cyl 5 along with extremely low oil pressure (11 psi at hot idle). At that point they said they fixed cyl 1 problem and they can't figure out why cyl 5 is now misfiring and recommended I take it to a different mechanic.
The new mechanic (mechanic 2) said they suspect the other mechanic screwed up the install, probably scoring the cam bearings causing the low oil pressure. Mechanic 1 says the bearing are probably out of tolerance causing the original cam to go out. Mechanic 1 also said it probably had low oil pressure to begin with (I never noticed low oil pressure and I have the temp/pressure screen on my panel on at all times)
More code problems to come but if mechanic 1 thinks the bearing were shot to begin with, why would he put in all the new parts? If it had low oil pressure, shouldn't that have been a sign (I do not buy this). I personally think they screwed up the electrical system when the alternator was shorted and also screwed something up inside during the install.
Well, now I am getting these additional codes and misfire on cyl 5 is infrequent now but does happen as seen on scanner.

I simply do not know what to do. I am out $5000 so far and have a truck in worse condition than when it was brought in. If I bring it back to mechanic 1, he could easily put the blame on something other than their work but he does seem honest. I personally do not trust their work though. If I take it back to mechanic 2, I will have to pay for the tear down just to prove it was mechanic 1's fault and cross fingers they can prove it.
Any suggestions? Hire an attorney and get my money back to put towards a new engine (I still think they fried the wiring). I would trade it in but I bought a new car since mechanic 1 had my truck for 4 months and I needed something to drive.
I am so lost as to what to do.
