I'm brand new to the forum its great! I just bought a 2006 F250 KR with 87,000miles. I`m on my third week of ownership. I haven`t had any issues to speak of. About a week in I swapped the stock coolant for CAT EC-1. However this morning when i went out to my truck, i turn the ignition to the on position and let it sit for about 15sec like ive always done. When i tried to start it the starter cranked abnormally slow for about 1-2 sec then all of a sudden began cranking normally till the truck fired up. Once the truck fired there was a cloud of greyish/whitish smoke they came out of the exhaust for about 2 second then dispated. Well the engine was smoking it did not stumble or act out of the ordinary. I am not going through any coolant or oil. Could this be related to STC fitting on the HPOP? Or the dummy/stand pipes? I monitored FISM voltage during key on and cranking and it is 48-49v. Battery voltage at start up is 11.8 volts I was thinking the battery voltage must have dipped low well the glow plugs were cycling. It is alittle cooler were i am the ambient air temp is 44F.
I appreciated any help or insight you could give me
