2019 Trax | Combustion Gasses Detected in Cooling System

This Trax presented with a suspected failed cylinder head gasket or cracked head. Oil looked somewhat murky. Moisture detected under oil cap, along with heavy blow by. Gurgling heard from dash board, indicating bubbles in the heater core. Is it air or carbon dioxide\monoxide? Let's find out with a simple block tester. In a healthy engine, fluid will remain bright blue. If the fluid changes to yellow green, combustion gasses are present in the cooling system. This indicated that exhaust gasses are escaping the combustion chamber and entering the cooling system. As this happens, coolant enters the engine oil. Bad news all around =(

I did that same test on my 2007 Pontiac Torrent but with a 2 liter bottle. Gotta love head gasket failures.

I remember that! Today was Judgement Day, for the Trax.
