About 3 months ago, I noticed that while cruising at approximate 75-80 mph I noticed my RPM is at about 3100 RPM, which I believe is a problem because it use to be lower. I then decided to do a compression test on all cylinder, 1 to 5 didn't have much variances but #6 was very low and had a big difference compared to all the other cylinders (approx 50% diff). Currently I am losing coolant about a 1/2 pint every month or so, I am unsure about oil consumption.
At the moment I am thinking it's a headgasket but does anyone know what other possible problems?
The motor has 122k on it.
