Hi Armand, Is there any signs of white ash deposits at all in the exhaust manifold or turbo outlet?

Expert:  Daniel Wilson replied 7 months ago.

Drop the oil pan and pressure test the cooling system and let it sit overnight or several hours. Let me know

Customer: replied 7 months ago.
I haven't open the manifold yet
But I m sure nothing is getting into pan
Expert:  Daniel Wilson replied 7 months ago.

Okay, Check the intake and exhaust manifold ports.

Expert:  Daniel Wilson replied 7 months ago.

Burnt coolant will leave white deposits out the exhaust ports
