2.7 eng seems to have a gravelly sound on light acc like loose valves only 2500 mi but always had the sound. ? Is it normal and does a hood under cover help with quieting the sound
Well, put another 7500 miles on it, and if nothing exciting happens (like RUD), you should be in the clear. The extra sound deadening on the OBX lux doesn't really cover it up fully, but it may help.
