Strange Vapor
I have an 03 zo6 with heads and cam all new gaskets and bolts. They have been installed for about 6 months or more. When driving my car to temperature then shutting down and starting a little while later, there seems to be white smoke as a very fine vapor. I smell antifreeze in the air but not strong. There is no fluid coming out of the exhaust mind you I have supermaxx heads and x pipe with cats. Those are my only mods, the car has about 45,000 miles on it. There no antifreeze elaks or oil leaks on any of the motor or on the ground. Just a fine vapor with a little antifreeze aroma. Can someone diagnose this for me?

If the fine white vapor is coming from your exhaust, more than likely it's a head gasket that's failed or maybe heads might need re-torqued. The leak might be so small that the exhaust is burning off most of it before it exits the tailpipes in vapor form.

If you can see the fine white vapor and smell antifreeze coming from your interior vents, then more than likely it's your heater core (or heater system somewhere).

I just ran my diagnostics:
PO135 Heated Oxygen Sensor Heater Circuit Bank 1 Sensor 1
PO155 Heated Oxygen Sensor Heater Circuit Bank 2 Sensor 1
U1160 Loss of Communications with LDCM
AO-LDCM B2282 Battery #1 Fault
AO-LDCM B2284 Battery #2 Fault
AO-LDCM U1064 Loss of Communications with BCM
A1-RDCM B2265 Horizontal Position Sensor Fault
A1-RDCM B2283 Battery #1 Fault
A1-RDCM B2285 Battery #2 Fault
A1-RDCM U1064 Loss of Communications with BCM
A6-SCM B0851 Battery 1 Out of Range
BO-RFA U1064 Loss of Communications with BCM
BO-RFA U1255 Serial Data Line Malfunction
Can someone explain to me how to fix these problems and what they actually mean?

I have a ground points diagram for a 2000, find one for your year or I can send you this one. That's either a wiring harness connector plug or ground, possibly removed a ground on the engine during work performed? I also had wild codes like that once from a loose battery ground.
