OEM Mopar Engine & Components

Many parts make up your factory engine. Its main parts are a block, cylinder head, and cylinders. Just about every cylinder has a piston, and every engine has valves, a valve cover, spark plugs, and an oil sump (or oil pan), among other parts. That's not to mention a camshaft and crankshaft.

What each of the parts of an engine does is straightforward. The valves, valve covers, and cylinder head on top of the block, for instance, seal the engine. Valves, though, are of two types: intake and exhaust. Intake valves regulate the ratio of air to fuel the engine burns for power, while exhaust valves regulate the fume levels inside the engine.

Valve covers protect the valves, the cylinder head keeps gas from escaping and prevents oil leakage, and the camshaft manages valve activity. Engine pistons compress that gas and oxygen mix as they pump, which makes more potential energy available. Spark plugs ignite that mix initially, it combusts, producing power, and the crankshaft turns that power into rotary motion. A drive shaft and transmission then use that motion to spin wheels and tires.

Every engine part needs lubrication to work, though. The oil pan or sump stores oil for that. Many other parts, such as gears, sprockets, rings, and bearings, make everything fit right.

If any parts wear out, though, engine problems follow. Symptoms of them include acceleration and idling trouble, lower fuel efficiency, and stalling. Your vehicle may not even start at all. Luckily, our auto parts store has the best possible solution for repairs: genuine OEM engine parts. They come straight from Mopar, ensuring they'll work with what you drive.
