Yea Im smoking white in the mornings then its just black smoke. Where is the EGR Valve?
If you are smoking white when you first start-up I am guessing that you have a EGR cooler failing. When mine started smoking white it did the same thing (only when starting cool). The good thing is that you identified the problem. The bad thing is that is cost a bit to fix.
What normally is happening is that the oil cooler is clogging up and that (because the oil cooler is first in the coolant line) overheats the EGR cooler making it over expand (it pulls on the tubes inside) to the point of leaking.
You need to replace the oil cooler and EGR cooler at the same time. Do some research and find a good mechanic that works on 6.0L. Get it repaired soon because your engine could lock up (hydro-lock is when you get fluid in the cylinder that will not compress when the piston compresses - it will break something internal). Right now you only have a small leak but it WILL get bigger and cause hydro-lock.
Here is the bad news. The cost for parts are expensive (on Ebay they cost about $900.00) and then add the labor cost. You are looking at a cost about $1500.00 to $2000.00
If you hydro-lock you are looking at a possible total engine replacement so this is why I said fix it as quick as you can.
I had mine repaired (at a friend mechanic) and he repaired it within 5 hours.
I am going to install a coolant filter in the very near future to help try to keep the dirt out of my new oil cooler. There are many write-ups on this mod on the forums
I hope this helps ya.
