I beleive the way I have my rocker cover set up is correct, but I'd like confirmation from those who really know.
I have a 1971 250ci engine in my 1965 C10. The engine was essentially free to me because it came inside a 1966 parts truck I bought. It runs very well.
To keep the engine bay looking like a 1965 230ci, I removed the 1971 rocker cover and replaced it with a 1965 cover that has the
Chevrolet script . These photos are of the same 1971 engine but I've obviously done some work.
The
1971 engine rocker cover has a fresh air intake on the left side just below the oil fill cap (black non-vented oil fill cap in photo). The 1971 cover has a PCV at the rear.
The
1965 cover does NOT have a fresh air valve on the side like the 1971, so I am using a vented oil fill cap. The PCV is the same.
Hambone has a thread discussing his rocker cover and this propmpted me to ask about mine.
