Have read through as many posts as I can over the last two nights and I'm still not 100% sure that this is correct.
The car is a 1978 Mini 1000 - I have had it about a month.
Car starts and runs fine. It idles okay at around 900-ish RPM. I have been using it as a short commute vehicle. No worrying oil leaks apart from tiny amount of "seepage" keeping the floor rust free.
I am about to embark on some routine tune up items (valve lash, then timing, then carb adjustment).
The breather hoses are old and perished in spots so I am going to replace them before the tune up but before I do I would like to confirm that the CCV circuit is correct - I have no idea if the system was modified previously.
Current components are an aftermarket rocker cover with a breather pipe, a vented oil filler cap, and a breather/can exiting the timing chain end. No breather on the clutch end. Carb is HS4 with a K&N pancake/cold intake type air filter attached directly to the carb.
A hose from the rocker cover breather port is connected to a T joint where it meets the hose from the timing chain side breather. The T is then connected via more hose to the carb at a point that sits between the piston and the throttle valve.
This seems correct for a CCV setup but I am wondering what the airflow path is, particularly given that the rocker cover is both open to the atmosphere (vented oil cap) and connected to the breather circuit. Does the crank case gas under pressure splt itself between the carb and the rocker cover?
Thanks in advance,
