I was thinking why people route the oil breather to a catch tank and vent to atmosphere? Is there any technical reason?
Ive got hold of a ford crank case breather/oil separator which i was gonna plumb inline before my catch tank. Then thought why not just put the exit pipe through the backing plate of the TB air filter? Sort of like you have to do with the weber 32/34 when you fit a bolt on K+N.
So anyone got any theories, facts? The logical position to fit the pipe would be along side the trumpet for cylinder 1. This would inevitably suck the gases straight down trumpet 1. Do you reckon this could have some adverse effects on engine wear? Maybe the valves getting gunky or promoting cylinder wear. Or maybe the opposite.
Ive heard somewhere venting to atmosphere is a technical MOT failure, and i suppose most of you are gonna say well ive passed X amount of MOT's with a catch tank.
I'm confident i can make sure that no actual oil will get blown out the final breather pipe with a combination of gravity, will power and the seperator.
watcha reckon ??
