Burning coolant

[tree98]

Only had a few minutes in the shop this morning before I had to head out but i stuck my fingers in the back of the EGR cooler...... nothing, dry as a bone. I even put the front end of the truck up on 8" blocks just to help give it some gravity.

Cooling system been on a regulator for about 14 hours 20-22 psi, had more external leaks of course, I don't know what it is with this thing wanting to leak all the time.

So anyway my plan now is to take the air filter piping off from the turbo inlet when I get back this afternoon and look for coolant.

If I don't find anything there, I guess maybe I'll try driving it with the pressure gauge on the cooling system and see if I can see a fluctuation in pressure while idling or under a load ?? Any other ideas?

I'm praying there's coolant in the turbo at this point.
