6.Uh0 Issues...again

Hey guys,
New to Diesels, new to the forum. Just a newbie.
Anyway, I have a 04 6.0 250 4x4. Bought it from a used dealer, (My mistake) and have been having issues with her.

1-Really hard, rough start/idle in the morning when not plugged in, accompanied by black smoke from exhaust.
-Plug it in? Is this normal for 6.0s?

2-absolutely no power on a cold go. When I just jump in and go w/out letting her warm up to Norm. Op. Temp. she has no go to her. Basically a bit more than an idle going down the road.
-Allow her to reach Norm. Op. Temp. before pushing down the road?

3-No Heat! The heater does not blow cold at Norm. Op. Temp until I get the
RPMs up, then she blows warm but not hot. Didn't know if this was common or not.

4-Had to clean the EGR the other day and cranked and revved to get the soot out of the motor. When I returned under the hood I noticed coolant coming through the turbo. I know that is NOT where coolant comes from. I have not seen coolant in the oil. Whats busted?
Spoke with a buddy of mine and he suggested coolant was low (For heating problem) which Im sure it would be due to blowing it all out of the turbo.

I have checked the batteries and the FICM. Batt's are good and FICM holds 49.3+ on all tests. (I have a 7 screw FICM).

I pulled the turbo pipe (? Left side of turbo reaching down to the left side of the lower radiator?) and cleaned it. She was caked in oil on the top but not bottom.

Plan to do an oil/filter, fuel filter, air filter and add RevX.
What weight oil do you guys recommend and what do you think my issues could be. Seems to me I bought a money pit. I mean, more so than normal.

If you got coolant in your intake this is signs of a blown or leaking EGR cooler. You need to get on this asap.
As far as the start up issue's, I cured 99% of my cold morning issue's with a healthy FICM and synthetic oil. I ran t6 and it has made a BIG diffrence. Also check out something like Rev-x or archoil.

Youre gonna blow it up if you dont get the egr cooler deleted, its been compromised. The reason it has failed is likely because your oil cooler is has plugged with gunk, and needs replaced as well.

Dont drive the truck until you get it fixed.

Delete egr immediately accompanied by flushing and replacing with new OEM oil cooler equivalent.
