Timing Belt

Ever heard the sad tale of a staggeringly steep repair bill from a broken timing belt? Bad news. Let's take a lesson from their woes and remember to think about our timing belt.First, let's review what a timing belt does. The top part of the engine over the cylinders is called the cylinder head. The head contains the valves. There's at least one valve that lets the fresh air into the cylinder. This air, mixed with fuel, burns to create power. Then another valve or two will open to allow the exhaust out of the engine. Each cylinder has 2 to 4 valves - that's 12 to 24 valves for a V-6, up to 32 values on a V-8. The opening and closing of the valves is done by a camshaft. The timing belt uses the rotation of the engine to drive the camshaft which opens and close the valves. It's called a timing belt because it has to be adjusted to rotate the camshaft to keep proper time with the engine so that everything's in sync.The timing belt is a toothed rubber belt. But some vehicles use ... read more

PCV Valve Replacement

Hello Greeley, let's talk about your often-unnoticed but extremely important PCV valve. The energy from exploding fuel is what powers your engine. But some of the vapors from the explosions escape into the lower part of the engine, called the crankcase. The crankcase is where your engine oil hangs out. These gases are about 70% unburned fuel. If the gases were allowed to stay in the crankcase, they would quickly contaminate the oil and turn it to sludge. Greeley folks know that sludge is one of the biggest enemies of your engine, clogging it up and eventually leading to expensive failures. Also, the pressure buildup would cause seals and gaskets to blow out. Therefore, these gases need to be vented out.Pre-1963, gasoline engines had a hose that let the  fumes vent out into the air. In 1963, the federal government required gas engines to have a special one-way valve installed to help reduce dangerous emissions. (Can you i ... read more

Greeley Drivers: Is It Time to Replace Your PCV Valve?

Greeley Drivers: Is It Time to Replace Your PCV Valve?

The crankcase is the lower part of the engine where the crankshaft is housed and where the engine oil lives. The crankshaft is connected to the pistons that power the engine. When you are diving around Greeley, fuel is burned in your vehicle engine, it pushes the pistons down and the crankshaft rotates and sends power to the transmission. Some of the explosive gases from combustion squeeze past the pistons and down into the crankcase.Now this gas is about 70% unburned fuel. If it were allowed to remain in the crankcase, it would contaminate the oil and quickly turn it to sludge. Sludge is like Vaseline and clogs passages in the engine, leading to damage. Also, the pressure build up would blow out seals and gaskets. So in the old days, there was just a hose that vented the crankcase out into the air. Obviously, not good for our air quality in Greeley, Colorado.Enter the PCV valve. It's a small, one-way valve that lets out the gases from the crankcase and routes them back into ... read more

PCV Valve Service at Phil's Pro Auto Service in Greeley

Today, we are talking about your PCV valve. Unburnt fuel is forced into the crankcase as your engine runs.  The PCV (positive crankcase ventilation) valve vents this unburnt fuel and oil vapors from the crankcase and sends it back into the air intake system to be burned in the engine.  A clogged PCV will not allow these vapors to escape. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause vehicle engine corrosion, something we see occasionally at Phil's Pro Auto Service. At high speeds on Colorado freeways, the pressure can build up to the point that gaskets and seals start to leak. Back in the old days, vehicles were simply installed with a hose that vented these gases out into the atmosphere. But starting in the 1964 model year, environmental protection laws required that these gases be recycled back into the air intake system to be mixed with fuel and burned in the vehicle's engine.This is much better for ... read more

Timing Belt Replacement in Greeley

Today we want to talk to Greeley drivers about timing belts. They're something that many drivers don't know much about and yet your vehicle won't run if it's broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner's manual, it's not the kind of thing that most Greeley area auto owners remember because it's not well understood.Let's review what a timing belt does. As most know, the engine's power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel, pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens at ... read more
