PCV has whistle and/or whine

Opps doesn't show the one I had in mine. This one comes in 3 different hose sizes.

Precision Flow-Adjustment Valves with Barbed Fittings for Chemicals

• Valve Type: Needle
• For Use With: Water, Oil, Air, Argon, Butane, Carbon Dioxide, Citric Acid, Deionized Water, Diesel Fuel, Ethanol, Ethylene Glycol, Gasoline, Helium, Hydrochloric Acid, Isopropyl Alcohol, Kerosene, Krypton, Methanol, Mineral Spirits, Natural Gas, Neon, Nitric Acid, Nitrogen, Oxygen, Phosphoric Acid, Propane, Salt Water, Soap Solutions, Sodium Hydroxide, Sodium Hypochlorite, Sulfuric Acid, Toluene, Xenon, Xylene
• Seal Material: PTFE Plastic
• Packing Material: PTFE Plastic
• Needle Material: PVDF Plastic

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a PTFE seal and a PVDF body. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Threads and a hex nut below the handle allow you to install these valves in instrument panels. They have a nut that can be tightened to compress the packing if it leaks.
