Where is the fresh air valve on a V-8?

Where is the fresh air valve on a V-8?

On a V-8 the typical fresh air source is the opposite valve cover from the PCV valve. Other applications utilize a PCV valve mounted centrally in the intake manifold, above the lifter galley, with a fresh air intake equipped on one or both valve covers.

Can a PCV valve still be used in a performance engine?

To further complicate matters, performance engine builds very seldom retain all stock components. So even if your vehicle’s PCV valve has a listing in the parts book, if the cam, heads, intake or any other modifications have been made the factory PCV recommendation will likely no longer be valid.

What are the symptoms of a stuck PCV valve?

Symptoms of a Stuck Open PCV Valve 1 Engine misfires at idle 2 Lean air-fuel mixture 3 Presence of engine oil in PCV valve or hose 4 Increased oil consumption 5 Hard engine start 6 Rough engine idle 7 Possibly black smoke 8 Oil fouled spark plugs More …

How is a PCV valve different from a road draft valve?

Whereas a road-draft tube vented crankcase vapors to the atmosphere, a PCV valve functions differently. With a PCV valve gases are fed back into the intake manifold as part of a fresh charge of air and fuel. This is accomplished by drawing in a clean source of fresh air via a breather.

What are the symptoms of a bad PCV valve?

7 Symptoms of a Bad PCV Valve. 1 Check Engine Light. 2 High Idle RPM/Rough Idle. 3 Lean/Rich Mixture. 4 Misfires. 5 Rough Acceleration. 6 Increased Oil Consumption & Oil Leaks. 7 White/Black/Blue Smoke from the Exhaust.

What are the symptoms of a bad EGR valve?

A rough idle upon starting the engine (that is, when the engine is cold) and sometimes at a stop light or while looking for a spot in a parking lot (that is, at low engine speeds in a warmed-up engine). Stalling when the engine idles. Increase in fuel consumption.

What do you need to know about a cylinder?

• Type of cylinder • CGA # • Valve  control • Manufacturer’s name • Pressure relief device • Outlet thread • Context – outside old storage unit

What should the temperature be for a CG 2 cylinder?

• Designed to melt at set temperatures • 165° F for CG‐2 –LPG • 212° F for CG‐3 – acetylene • Pressure <500 psi • Prevents overpressure due to fire • Does not reclose Pressure End Fusible Plugs : CG‐2, CG‐3

Can you tell if a valve is a PCV valve?

Making matters worse, PCV valve manufacturers and OEMs are reluctant to share any PCV flow data. Without this information, the consumer‘s only option is to purely guess at which valves have which flow characteristics. To further complicate matters, performance engine builds very seldom retain all stock components.
