 Hi all - I'm looking for some information/confirmation of the crankcase ventilation and oil capture setup that would have been on the car from stock. My car is a 1973, vin 12947 with engine 3077.

I gather that all cars have a port in the crankcase, some cars also had a drain tube that drained oil from a separator back into the sump, and later cars also had a tube running from the rocker cover to the airbox.

My car only has the crankcase outlet - nothing else remained on the car when I got it.

Picture attached is the crankcase port into which I have put a breather while I get it running.

I am planning on running a tube from the crankcase to an oil catch can and either venting it or running a tune to an airbox when I eventually get one.

Any thoughts on what is best here - should I install a rocker cover line as well? And also, I'm curious as to the reason there is a spring shown in the system diagram where the tube enters the crankcase.

Cheers,

Corey
