2005 Mustang valve covers protect the set of valves and mechanisms (the valve train) that open and close. Consisting of push rods, valve springs, lifters and rocker arms, valve covers represent a necessary and vital contribution to the smooth operation of your Mustang.

Vehicles with more than 30,000 miles on them nearly always have some kind of oil seepage due to normal wear and tear. Valve cover gaskets with signs of oil seepage around them may not need an immediate replacement, but don't let a worn 2005 Mustang valve cover remain on your vehicle for too long. Blown valve cover gaskets will eventually cause serious, more expensive problems with your pony car.
