(1) ‘NOS’ AC PCV Valve CV273......GM #5646286

This is a ‘NOS’ AC Vintage Ventilation Valve (aka PCV Valve) sweetventidk1989sweetventidk1989sweetventidk1989swethe part your car rolled off the assembly line with. It is all New ‘NOS’, has never been used, and was made in the USA.

Box Dated 263 (February 1963)

This Unique Style CV273 (GM #5646286), to the best of my knowledge, has not been produced by AC Spark Plug Division, since about 1965.

The later versions (1965 & Newer) are labeled CV608C PCV Valve (GM #6421972). Then the CV608C was discontinued and superseded by CV679C (GM#6421974).

However, a little research shows that the original CV273 (Ventilator Valve) is much heavier, is made from heavy milled steel, has a paper label and is black. While the CV608C or CV679C (PCV Valves) is lighter, appears different, and is clearly manufactured from a light gauge shiny stamped steel.

Also, note the CV273 box,  has no zip code, which became mandatory sometime on or about 1967. This CV273 is a survivor, and though its little box shows minor shelf wear, the Valve is in Excellent NOS Condition (see all the photos). 

Always check your specification manuals and independently confirm the AC CV273 is correct for your specific engine and vehicle.

My Vintage NOS PCV Valves may be between 30-50+ years of age. The box, which contains the Valve, may show typical or various signs of shelf-wear as it is a paper product.  However, when you open the box you will find your Valve, to truly be in, the real deal ‘NOS’ condition.
