How is the oil cap removed from the valve cover? This one won't come out no how. There must be something simple I'm missing. I had to funnel oil in through the valve cover breather hole.
Also, how was the valve cover breather fed? Did it have a tube running over to the air filter housing from the valve cover? I see no hole in the housing.
If I am remembering right, on the 66 cover the oil cap should be a breather, the pcv valve goes into the top of the valve cover at the back and the hole your's has with a breather in it won't even be there

Here are two photos of a stock 230 in a '65 Biscayne, we had one in our 65 Laurentian, sadly I can recall Dad cursing it on cottage runs because it wasn't up to the 61's 261 on passing power.
Wow! A 230 with power steering and air conditioning. Must be a real ball of fire to drive.
As for the plug my 69 Chevy Pickup has the same setup which is kind of a pain. I find, especially in winter, that you have to actually have the engine warmed up thoroughly to soften the cap enough to pull it out without a real fight. Putting it in cold is pretty much impossible.
Well based on that casting number I'm going out on a limb and declaring this to be a Flint engine that big F in the number. So being a Canadian Pontiac it would have had a McKinnon engine which is a K. It's not an original engine imo.
The CBJ was a clue for me. So far I have never seen a 3 letter code on a Canadian Pontiac (Chevy) engine before 1969. With that said, there is one exception.
The mid 60's engines that had a choice of Holley or Rochester carb sometimes had an H or an R after the normal 2 letter engine suffix code, but to decode those you just ignore the R or H because it seems virtually no decoders recognize them.
