Hello people!
Consider this early B-series engine breathing system: non-vented oil cap, a
hose linking the rocker cover to the air filter and a metal tube from the
rear chest cover pointing downwards.
Now, consider this simple modification:
a. throw away the old air filter and put a pancake-type in its place
b. use a long rubber hose from the rocker cover downwards, alongside the
chest cover metal tube
Will preformance improve at all? Breathing? Emissions measured at the
exhaust tailpipe? I've seen it done and the owner told me his car pulled a
little bit better and gave lower emissions readings.
I'm not sure if the oil cap should remain a non-vented item or be replaced
with a vented type though...
Your input is welcome.
