Tight Valve What's too Tight
Checked the valves at 12065 miles on my '05 this week, and found two intake valves tight. The one I'm concerned about is the first one in the train. It was a tight .003 . Should I be concerned about a burned valve? Fuel mileage dropped about 600 miles back, by about 4 mpg at the same elevation. I'm now getting less mileage, 38 mpg solo now, than when I was pulling my trailer which was about 40.5 mpg. All mpg is actual measured, not computer.
Need input please.
