1965 230 six. How does the oil cap come out?
Permalink  

Dumb question.

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.

Thanks, Mark

That is an oil cap from a later engine. PULL!!!

I'm assuming both the valve cover and cap must be from a later engine.

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

Ya that cap is rubber, but probably hard as a rock now.  just pull like hell.

You need to replace it with a vented breather cap that will allow fresh air in, otherwise it wont get fresh air into the crankcase

It does have a breather on the side though Dave, even though it's not the right setup for that car.

Oh, ya, i just noticed that.  right it will all work,  but the valve cover is from a 69 or later motor.

Maybe the engine is later?

Where and what numbers on the block will decipher it?

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.

I found something about the suffix BJ meaning 1969, No Air, Taxi or Police, Powerglide. Maybe it was a GM replacement engine?
