Engine Cooling problem
2002 Dodge Durango V8 Four Wheel Drive Automatic 160000 miles
I recently had to refill the coolant after the truck overheated one day. I initially replaced any easily serviceablt items (Water pump, Thermostat, Rad Cap), and had the radiator pressure tested while it was out. I have noticed that the coolant level is steadily going down despite all of this. So I've performed a few tests:
Pressure tested the colling system, and after filling it to 19-20 psi, it steadily looses pressure after a few minutes.
I ran a compression test, which seems normal, however the number 2 plug always comes out wet and the others appear dry.
In addition I have been getting Cyl 2 misfire codes.
Lastly, I have noticed occaisional sweet smell from exhaust.
What is the most likely cause, Head, Head gasket, intake gasket?
have the same problem?
