now now, before you take my head off for starting ANOTHER thread on oil catch cans, hear me out first, at least
on most (high performance) setups, i see that modders plumb both breathers off the rocker cover to a catch can. on others, i see only the main breather (one without the pcv valve) plumbed to the catch can and the pcv valve hose left in stock position - leading back to the intake mani.
ok, here's why i bring this up; the reason for having a catch can in the first place is to ensure the intake track stays clean and oil/sludge free. if the pcv valve hose is left in place then some oil will still make it to the intake mani when the engine is ticking over since that's when the most blow-by makes it through. now i know for emissions reasons etc, this is the reason toyota did it that way but from a modders perspective, isn't it pointless to have a catch can and only tap from one of the breathers..? i guess those who do perhaps do so because:
a) the catch cans they have only have one inlet..?
b) budget maybe..?
c) they see no need to..?
just thinking out loud..
