If your vehicle has been running roughly or losing power, there may be a lack of pressure in one or more cylinders. To determine whether pressure is escaping from the engine, you need to have your the compression in the cylinders. Our expoert mechanics will measures the amount of pressure that the piston exerts on the fuel/air mixture before the spark plug fires the mixture.
If there isn’t enough pressure, it's escaping through one of the valve openings (because the valve is improperly adjusted or worn), down past the rings on the piston or through a blown head gasket. It becomes a big job and should only be handled by a professional. Bring your vehicle to us and we'll assess and see what needs to be done.
