Engine Repair & Services

     The engine is probably the most important component of your car, that is why it is vital to keep it running top notch. KC Complete Auto can show what services we provide to help get the most out of your engine. Here is a list of some of the repairs that we offer at our service shops.

Tune Ups – Are important as normal vehicle usage causes various parts of your engine to lose their efficiency because of under-the-hood temperature and vibration. Regular tune-ups help maintain vehicle safety and performance by ensuring that worn or faulty parts are replaced promptly. Tune-ups can help you achieve maximum fuel efficiency and vehicle performance.

You should schedule a tune-up if you notice any of the following; Your gas mileage is decreasing, experience a loss of power or torque, the engine sounds like it’s running rough or stalls out at a stop, there is knocking or pinging sounds when accelerating or after the ignition is turned off

Head and Valve Cover Gaskets – Oil leaks and gasket seepage are very common as cars age and get up into higher mileage. Also coolant, which is used to keep the engine cool, can seep into the engine causing white smoke to come out of the exhaust, very commonly a new head gasket is needed. If you see any leaking or seeping we will be more that happy to inform current state of leak and gasket.

Intake Manifold – The intake manifold is the part of the engine that supplies the fuel/air mixture to the cylinders to be combusted.

Exhaust Manifold and Gasket – The exhaust manifold is the first part outside of the engine gas passes through when exiting the engine. This is an important part that sees extreme temperatures from the exiting gases. You want to make sure the gasket and manifold are intact and working properly so that you exhaust doesn’t have any leaks.

Engine Replacement – Is your engine on its last leg? It may be time to replace the engine and get you back on the road safely. Sometimes poor maintenance by previous owners can take a toll on the engine and render it useless before its time, we can help you! Let our ASE technicians assist you in swapping your old motor out with a lower mileage, good running replacement. 

 

Here is a cross sectional view of the inside of a cylinder in in your vehicle.

The four strokes refer to intake, compression, combustion (power) and exhaust strokes that occur during two crankshaft rotations per power cycle.

  1. INTAKE stroke: on the intake or induction stroke of the piston, the piston descends from the top of the cylinder to the bottom of the cylinder, increasing the volume of the cylinder. A mixture of fuel and air, or just air in a diesel engine, is forced by atmospheric (or greater) pressure into the cylinder through the intake port. The intake valve(s) then closes. The volume of air/fuel mixture that is drawn into the cylinder, relative to the maximum volume of the cylinder, is called the volumetric efficiency of the engine.
  2. COMPRESSION stroke: with both intake and exhaust valves closed, the piston returns to the top of the cylinder compressing the air or fuel-air mixture into the combustion chamber of the cylinder head. During the compression stroke the temperature of the air or fuel-air mixture rises by several hundred degrees.
  3. POWER stroke: this is the start of the second revolution of the cycle. While the piston is close to Top Dead Center, the compressed air–fuel mixture in a gasoline engine is ignited, usually by a spark plug, or fuel is injected into a diesel engine, which ignites due to the heat generated in the air during the compression stroke. The resulting pressure from the combustion of the compressed fuel-air mixture forces the piston back down toward bottom dead center.
  4. EXHAUST stroke: during the exhaust stroke, the piston once again returns to top dead center while the exhaust valve is open. This action expels the spent fuel-air mixture through the exhaust valve(s).
