Coolant in Valve Covers
I have a few questions about why my truck is burning coolcant, and also why there is coolcant in the valve covers. 2003 CC LB SRW 7.3 w/ basic mods.
#1 Would cracked injector sleeves/cups lead to the burning of coolant?
#2 Would cracked injector sleeves/cups lead to coolant in the valve covers?
#3 What else might be the cause of burning coolant?
#4 Would the truck run differently with a cracked head, or broken head gasket?
Background information: The first day I noticed the white smoke it was only when I was at idle, and I didn't notice it while driving. Also on the same day I hooked up to a 18k pound trailer and drove through some moderately hilly terrain, round trip no more than 100 miles. Upon return from that trip I checked my coolant level and was quite low. I added 2 gallons of coolant and it didn't quite fill it. Ever since that day I have driven the truck a grand total of 35 miles to and from work, and have added another 3/4 of a gallon of coolant. I notice large clouds of white smoke at stop lights, but couldn't notice it while driving. I have no loss of power, no rough idle, start ups are regular.
Thanks and PLEASE HELP!!!

I had cracked sleeves and was burning antifreeze, but i was getting large amounts of fuel in my degass bottle. I would think that a cracked cup would always lead to fuel in the bottle due to the fact the fuel system is running more pressure than coolant. So really as your driving you shouldnt get coolant in the cylinder. However if you turn the truck off and loose that fuel pressure then your coolant could leak in cup.
I would do a compression test.
