Hi my name is***** will be glad to help. Drop the engine oil pan down and pressure test the cooling system. this will single out which cylinder or liner is leaking. Also if this is an EGR engine and you have white smoke and white ash deposits in the exhaust from coolant burning in the exhaust it could be a faulty EGR cooler. Do the pressure test to check for both unless your engine is non EGR. Let me know
Okay. The pressure test will reveal the problem liner or head gasket issue.
