ok, so I just completed doing head gaskets, EGR delete and oil cooler rebuild. I took the cab off, the heads got machined .008", i installed ARP studs and Black Onyx gaskets and I installed an RCD EGR delete, I used a Ford oil cooler rebuild kit. SO, we got it put back together, got it started and it had a miss, seemed like one cylinder wasn't working. it had white smoke out of the exhaust as well. SO we scanned it and it passed the buzz test and did a contribution test and it said that cylinder 1 failed contribution test. Put in a new injector, it still misses, still chugs and still smokes white. I talked to a friend who's done a 6.0, said it needs to be driven to get the system cleared of air and such. so I drove 56 miles today, half of the miles were at 2800-3200 rpm. it still misses, still smokes and still chugs
it sounds like it could be a compression issue, but idk, please help!
and at idle it shakes, but the injector clatter sounds like a normal idle when you listen, but the exhaust pulses and has a chugging sound
