I have a 1996 Cummins C 8.3L - 210 hp. Last week, doing my pre-check, I noticed my coolant level was almost 1 gallon low (never low). I then noticed the green tint to the oil. I did notice a coolant smell from the breather. I immediately changed the oil and filter. Still can smell coolant lightly from the breather, but an oil change doesn't get all of the oil out. What would cause this? Head gasket? The truck is running and sounds great. Exhaust looks good, no white. There are no leaks under the truck. There is NO oil in the coolant, so should rule out oil cooler. If not the head gasket, could the air compressor leak coolant into the oil? Please give me your thoughts and I will continue to monitor as I need to use the truck this week.
have the same problem?
