The positive crankcase ventilation system was one of the earliest emission-control devices. It draws leftover combustion gases from the crankcase (the oil pan and bottom of the engine) and routes them back into the engine, where they’re burned in the combustion chambers instead of escaping into the atmosphere.

Oxygen sensors are a critical component of the fuel and emissions systems because they monitor the amount of oxygen in the exhaust and transmit that information to the engine computer, which adjusts the air-fuel mixture accordingly

The recommended intervals for changing brake fluid are all over the board depending on the manufacturer, from as often as every two years to never.

Most vehicles have a rubber belt on the front of the engine that drives accessories such as the air-conditioning compressor, power steering pump and alternator. If this accessory drive belt (also called a V or serpentine belt) breaks, the battery won’t get charged, the air conditioner won’t blow cold air and the power steering will…

A car’s air filter is a small and inexpensive part; but it’s essential to performance & fuel economy. A good/clean air filter is a basic need for the proper operation of a car. A clean air filter leads to enhanced gas mileage, increased engine life, better acceleration, lower emissions & overall enhanced engine performance.

When a ball joints is worn it allows for too much movement in the suspension, so the driver may feel more vibrations – or hear squeaks or rattles on bumpy surfaces or when turning — caused by looseness in the suspension. Other signs of worn ball joints include uneven tire wear and steering that wanders instead…

This is a lovely question, but first we must define what “acting funny” means when referring to one’s drivetrain before recommending a course of action. Do any of the following seem familiar to you?

The timing belt is a notched rubber belt, sometimes called a Gilmer belt. This belt allows the crankshaft to drive the camshaft, which in turn opens and closes the valves. Without this belt, the engine can’t run.

A drive axle is essentially a half axle, so named because it does half of the job, extending from a transaxle (front wheel drive car)  or differential (rear wheel drive car) to one of the wheels. Its twin on the other side completes the set. Because they’re simply shafts, half shafts age well, but the…

I’m sure you have heard your mechanic say, “ahh!! the catalyst is bad” or “the front exhaust has spoilt”, and you are like , what is this one saying , well the catalytic converter is part of your car’s emissions systems, and it plays a crucial role.   It’s located upstream of the muffler, close…
