I'm running a 2" dia valve cover breather on each side of the motor. No PCV valve or anything. I am getting a small amount of oil misting and recently a oil leak at the back of the intake manifold where it mates to the flat part of the block valley (between cylinder banks) I had sealed this all with a liberal amount of Ultra Grey RTV but it recently started leaking.
Question is should I be running these breathers, or should I switch to a PCV/hose system that vents the pressure and oil fumes back into the air filter? I have read that just using breathers doesn't really vent the pressure as well and having the intake "suck" the pressure from the crankcase. Bottom line I don't want excess crankcase pressure blowing oil seals or RTV out and making leaks everywhere. Whats the best setup? (Motor is fuel injected, if that makes a difference)
