While driving on over 60 mph it seems the rpms are a little high. Always over 3000. Is this normal? I have an oil leak but not sure where it is coming from just had an oil change today and mech said the valve cover gasket needs to be replaced. Last question, I am barely getting any warm air when I have the heat on. I am getting plenty of air though. Could it be the thermostat? Any information/advice or help would be greatly appreciated!
