Hi Armand, Is there any signs of white ash deposits at all in the exhaust manifold or turbo outlet?
Drop the oil pan and pressure test the cooling system and let it sit overnight or several hours. Let me know
Okay, Check the intake and exhaust manifold ports.
Burnt coolant will leave white deposits out the exhaust ports
Yes or an head gasket or an injector cup problem
Hi Armand, Did you get this resolved?
