Hey everyone. Wondering if anyone can recommend what next. Recently started getting codes P026B, and P020B,C,sometimes D. They come in randomly. Truck is 2014 6.7. Completely stock. They are injector codes but just going through everything I’ve changed fuel filters, checked injector harness, ohm’d injectors, checked transfer pump fuel flow. Everything is checking out. Just wondering if I am possibly missing something before I pull out the credit card. Cheers.

Need to change cam gear. I don’t have a dedicated tool for this. I got the axle puller as true as possible. If I apply a little heat, do I risk doing any damage to the gear/cam?

I watched your video on venturi tubes and I would like to implement this on my next build. I have all three variations of the oem common rail valve cover laying around. I like the look of the 6.7 cover, and the ccv filters are cheap and readily available. Also, the blowby tube is on the exhaust side of the engine. Do you see any problem with using the 6.7 oem valve cover to connect to the venturi system? Thanks, SW

So long story short(well semi short). I bought my truck way back in August now previous owner did a head gasket roughly forty Thousand kms before I bought the truck and with in 24 hours of owing I blew the gasket so after a couple months of denial, I replaced it in December took my head to a machine shop local and they said it was blown on 4-5 5-6 steam port and they took some off, they didn't specify. I put it all together with a oe Cummins gasket and after 3 weeks of driving it under boost and high rpm I head gasket chatter and coolant blowing everywhere. The block was straight when I had the head off. What's my best option ie just replace the gasket, replace the head with a known good one. I'm leaning towards just replacing the head but want your guys opinion. And yes the truck is tune and deleted and it has a mini max v1 and the truck has 411,000k on it
