recently bought an 06 f150 5.4L triton and have already learned more than I could ever want to know about these things and yet I’m still stumped. I’m hoping someone has experienced similar problems and was able to solve it so they can guide me.

Okay so I bought it from a guy who apparently buys these model trucks after the timing components tear up and does the timing job and resells them. Well he told me this one had just been through the whole timing job but I only made it about 10 miles down the road and lost all oil pressure and had a terrible knocking so I towed it back to him and he said he would redo it for free. So I ordered cast iron replacement parts (timing guides, tensioners, new solenoids) and he allegedly used these when he redid the timing on it. Anyway, I get the truck back like two weeks later and the guy says “it’ll idle rough for the first 100 miles until the Idle pos. Sensor calibrates” and after some driving it cleared up a little but still didn’t clear up like it should have. So I figured since the catalytic converters had been removed along with both downstream o2 sensors, that and the significant exhaust leak at the flange where the manifold meets the exhaust pipe was most likely causing the sputtering until I ran the codes and it’s saying it’s the bank 2 camshaft sensors. I’ve tried the alternator trick, checked the VCT solenoid for debris, and currently have the driver side valve cover off and as far as I can tell it all looks normal? So I thought maybe a vacuum leak but I can’t hear well enough to find it over the massive exhaust leak. Any suggestions?
