Was driving on freeway (engine running fine) then after exiting and catching a red light, the engine was idling rough. After revving the throttle a bit, it seemed to smooth out.
Then the next day, I went to move the truck and when I started it up, it acted like it was running on 3 cylinders :(
Pulled the plugs today and the #4 (rear) plug was wet with oil.
There doesn't *seem* to be any oil in the coolant or coolant in the oil, so what am I encountering? Blown head gasket? Bad valve seal?
What ever the cause, it may just be time to retire the truck :(
TIA
