1969 Corvette small block oil cap

[D S.]

I have read in the 1970-1972 that the small block oil cap (LT-1 excepted) is supposed to be painted steel with a large squarish center rivet with a stamped cross pattern. What did the 1969 small block oil cap look like and what words if any were stamped on it?

Thanks,

It looked like this. The script is lightly stamped and is often "obscured" by engine paint, but it says

"ENGINE OIL FILL"

"AC-FC2"

I should also have added that 71-72 don't use this cap. They use a rubber plug, instead. Also, I don't know of any Corvette big blocks that ever used this cap. When this cap was introduced, Corvette big blocks used chrome valve covers and a Stant-manufactured chrome cap. By the time that big blocks went back to painted valve covers, the rubber plug style was in use and was used right to the end of the big block era in Corvettes. Small blocks went back to the twist-on style cap for 1973, but Corvette big blocks never did.

Re: 1969 Corvette small block oil cap

Thanks, Joe. The 1970-1972 Corvette Judging Guide, 4th Edition, top of page 58 is confusing. It implies that there were no words stamped on the 1970 small block cap and then it goes on to state, "Late 1972s have been seen with the same rivet style as 1970, but the words ENGINE OIL FILL AC-F2 are embossed in a circle around the rivet." That lead me to believe that only the late 1972 caps had those words so that is what gave rise to my posting the 1969 oil cap question. A friend who has a small block 1969 coupe with painted valve covers has a chrome oil cap correct for big blocks on it. I'm trying to get him to sell or trade me the BB cap for a correct SB cap and I want him to have the correct, original cap for his 1969 small block so I can get a correct BB cap for my '70.

The cap pictured is a late 1969 cap. However, the same cap was used for small blocks with painted valve covers for earlier 1969 and for 1970. The late 1972 (when they went back to the twist-on cap) used the same cap. I once "harvested" a whole bunch of these caps at a self-service-type salvage yard. All of the 1969-70 and 73-74 caps from Chevrolets were the same and all had the same stamping on them as I described.

Sometimes, the stamping is so light that it is completely obscured by the engine paint and that might lead someone to believe it's not there. But, it is there.

There were other VERY similar caps used later on Chevrolets and other GM engines which had different FC-numbers. I don't really know what the difference between them was except for the number. I examined and compared these carefully and could find no apparent difference.

Re: 1969 Corvette small block oil cap

Terry, somehow you missed the point of my question. Nowhere did I infer or state that I expect the 1970-1972 JG to make any reference to 1969 caps. My question was explicit when I wanted to know what the 1969 caps looked like as I have no other references at my disposal and I wanted to get a friend a correct cap for his 1969 small block Corvette. That's why I post questions here. If you have a 1969 JG and can get a description from it regarding small block cap descriptions then please do and add it to this post. If the 1970-1972 4th Edition needs revising, so be it. Git 'er done.

I do have a 1968-9 TIM&JG, but not here at work, and I plan to leave for Waco shortly so my time with both the JM AND the Internet is limited. Perhaps someone else on this board has the latest 1968-68 TIM&JG and has the time to look up the information you want and keyboard it in. Or if you want I'll bring it to Waco and you can look at it there -- although I suspect there will be plenty of JMs there.

"If the 1970-1972 4th Edition needs revising, so be it. Git 'er done."

The time it takes to do that is beyond my control. The pace of that project is in the hands of others.

Re: 1969 Corvette small block oil cap

Terry, if you're going to be in Waco for the regional meet I'll be there sometime Saturday morning. You show me and I'll learn.

I'm bringing some parts for some of the members who will be there...Joe Blount (maybe), Melissa Neiman, Don Cast, Herschell Andrews. I'm also stopping off in West for some jalapeno and cheese sausage and maybe some kolaches. They have prune kolaches, too. Want anything?

Re: 1969 Corvette small block oil cap

I'll bring the 68/69 TIM&JG with me. I doubt my cell will work there -- probably no bars. I'll bring it though. On*Star might work, but I'm not sure with the car inside the building. Ask anyone at the front desk -- they will call me or point out where I am. Everyone knows me. I will have the Advanced Judging School going on.

Kolaches ;-) -- I live in what used to be a predominantly Bohemian community. There are still some bakeries of that ethnicity here. Prune are just the start. Ironic there is a Polish/Bohemian bakery down there. I don't go to Waco for the food. The Louisiana folks are the foodies, but that is another story.

See you Saturday. Time to go to bed.

Don't forget that the 69 small block 350 HP had aluminum covers and a chrome cap. Mine is out for a paint job but as I remember there is nothing stamped on the chrome cap. If you want I can look through my pictures.

Scott:
This is my first attempt at posting photos so here goes. Attached (I hope) is a photo of my early '69 oil cap. The lettering is: "ENGINE OIL FILL" and "AC FC 2".
