Had a bent push rod, replaced but still misfires
I just bought this truck. It had a bent push rod, the shop I bought it from said they had been starting it with either because it wouldn't start without it and it bent. I tore it apart and did head gaskets and studs, had the heads machined, new oil cooler, egr delete, one new push rod (exhaust, passenger side rear most cylinder) all new gaskets, seals, o-rings, injector o-rings. Started it up and it still misfires but not like it used to, no huge popping noise anymore. Cranking it sounds like it is low on compression. I looked at the valves but did not pull them, looked at the cylinder and it looked ok, the piston had a little extra carbon, but the truck was driven in and out of the shop on 7. Looked at the lifter and but didn't pull it, didn't look like it had any damage. Smokes white smoke out the exhaust. What did I miss?
