Thoughts on diamater of lines?

My -12N lines just turned up and they are a bit bigger than what i was expecting, could to large a lines be a problem?

2L engine requires 2L catch tank doesnt it also?

The lines should be fine.

2L engine requires a 1L tank minimum, 2.1+L engines needs 2L tank, personally would aim for at least a 1.5L tank.

5.1 (7) Oil catch tanks: shall be fitted to engines with open circuit crankcase breathing

systems as follows;

(a) Engines up to and including 2000cc shall have a minimum of 1 litre catch tank

capacity.

(B) Engines exceeding 2000cc shall have a minimum of 2 litre catch tank capacity.

Note: Do not apply equivalence factor multipliers.

I have a -6 (3/8 hose I think) line on my setup as it's the same size hose as original, there's oil in the catch can so it obviously works

My new tank will be just below 1.5 litres for my 1800 motor

Also, I have not tested the blowby yet as the car hasn't been running due to starter motor, but I will test it in due course
