PCV 736C Sighting in a 1973 Corvette

Joe,
Service stocks can stay on shelves for decades, just recently, as an example, a dealer closed and the buyout netted a case of 1966 dated PCV valves.

Remember, service part number was different, it went to the parts depot and they also had a system of keeping parts current. Where the parts aged was the dealer inventory, recall that this was before computerization, before bar codes, and yes (Tom, using I again), knew and talked to the inventory control people on the stocks of these parts. Back then I went to Lansing to get a nos NOS set of side pipes and covers for the mid years, great times.

Keith, there is one 67 736 valve on ebay as Joe says, big dollars.


And Tom," I" was in that 1st paragraph twice, I is first tense, ENG101.

OK - I go from SURE that it was replaced to KNOW it was replaced. I see what you mean about big bucks. I think I'll stick with my known replacement.

I remember back in the 80s in Calif, a local parts store was closing after 50+ years in business. There were bins of old parts covered in dust. I didn't know what to look for so only bought a few that I thought I could use at the time. I did buy the 6' tall old safe (took a crane to move) and the 1950s vintage Sun Tester both of which I still have in my shop.

For this valve to have been installed on the car in SERVICE two things would have had to have happened. First, the supplier would have had to have made a mistake in determining the proper replacement valve (i.e. the 769C was the valve always cataloged for the application). Second, assuming this configuration valve was not manufactured after 1969, the supplier would have had to have drawn the valve out of very old stock since the valve would likely not have needed replacement before at least about 1975 or 76. The AC 736C was not the kind of part that would have languished in stock inasmuch as it was widely applicable to many 1965-72 GM cars and trucks.

When it requires multiple coincidences to explain something, I highly doubt the premise on which the "something" is based.

It's irrelevant...you mixed person agreement...it's either one or the other not a mix of what you deem correct! And you're intro used "you" twice which confuses readers that pay attention to these English writing irregularities.

Tom, you never spend your years in the OEM design, manufacturing, and supplier world. It is a lot more cut and dry. I was there in the late 70's when you guys didn't give 2 cents for a mid-year save a split window. I went to the print file and pulled the prints to restored a 1966 in the time of 79-81 to the print. There were changes in prints, and AIM, and all that stuff was very well documented. Some people listening in have those books and documents.

I asked the owner of the 736C above to measure between the arrows in the photo below as per the request above. He sent back that it is
15/16".
