Understanding the Importance of Fuel System Cleaning and PCV Valve Service
May 23, 2024
Did you know that the hot gases produced in your vehicle's engine contain about seventy percent unburned fuel?
These gases can mix with the engine oil, leading to harmful engine oil sludge and corrosion. At David's Automotive Repair, we've occasionally seen engine damage caused by this.
When your vehicle's engine is running, fuel is burned to generate power. While most of the exhaust exits through the exhaust system, some of it can bypass the pistons and enter the crankcase, which is the bottom area of the engine that holds the oil.
That's where the PCV Valve comes in. PCV stands for Positive Crankcase Ventilation. It's a small but important part that helps vent these gases from the crankcase back into the air intake system to be burned in the engine.
Now, let's talk about fuel system cleaning. Having a clean fuel system is crucial for efficient engine performance. Cleaner fuel burns more efficiently, resulting in more power and better fuel economy, ultimately saving you money at the pump.
It's essential to use good quality gas from major brands, as they contain detergents that prevent the buildup of gum and varnish in the fuel system. Cheaper gas may lead to rapid buildup of dirt and rust in the fuel tank over time.
The fuel filter plays a vital role in filtering out dirt and rust from the fuel before it reaches the engine. A clogged fuel filter can allow dirty fuel to bypass the filter and potentially cause damage to the fuel injectors and cylinders.
Professional fuel system cleaning involves using special cleaning chemicals and methods to clean out the throttle body and fuel injectors. Clean fuel injectors ensure precise fuel delivery, improving engine performance and fuel efficiency.
In addition to fuel system cleaning, it's important to maintain other components like the engine air filter and PCV valve. A dirty air filter can allow dirt into the engine, while a sticky PCV valve can disrupt the proper functioning of the ventilation system.
By performing regular fuel system maintenance and PCV valve service, you can ensure that your engine's air and fuel remain clean, resulting in better fuel economy and engine power. Remember to consult your owner's manual or service advisor for recommended service intervals for these components.

While most people think cold kills batteries, extreme heat actually wears them down faster. High temperatures can cause fluid inside the battery to evaporate, weaken its charge, and shorten its lifespan.

Nobody wants to be stuck with a dead battery in a hot parking lot or on the side of the road. At David’s Automotive Repair, we offer quick and accurate battery testing to give you peace of mind before the next heatwave rolls in.

Belts keep systems like your alternator and power steering working. Hoses carry important fluids like coolant and help your engine stay at the right temperature. Over time, heat and wear can cause them to crack , fray , or leak . If a belt breaks or a hose bursts while you’re driving, it could lead to engine damage or even leave you stuck on the side of the road. That’s why it’s smart to have them checked regularly—especially before long trips or hot summer days. If you’re unsure about the condition of your belts and hoses, we’re here to help with a quick check. Call 972-625-1836 to make a reservation to have your belts and hoses inspected by a certified technician.
High temperatures can cause fluids to thin out , break down faster, or even evaporate —putting your car at risk for overheating or part failure. If your coolant is low, your engine can overheat.
