Now that I havent heard. I thought the breather was for the preasure to excape. I didnt think anything gets sucked in, there for you would not have a vaccum leak.Mike Kopstain said:Also keep in mind that if your stock PCV system is in tact and you add breathers you are creating a fairly significant vacuum leak which in the very least makes tuning interesting.![]()
well I find that odd considering when we did dave's car he forgot the breather and it was blowing out around the oil fill cap hence thats positive pressure on the crank case. Also several club gp memebers have blocked thier pcv without breathers and blown oil out the dipstick tube.FastGS88 said:without a breather there WOULD be vacuum in the block. The supercharger housing, where the PCV valve is located, is under negative pressure, and will place te entire crankcse inder negative pressure if the intake of the PCV system is blocked, like with an LS1 TB. If you'd like to read a more detailed outline of the system, i explained it here, i dont feel like retyping it.

well on a camaro is you just add FI the dip stick will pop out unless you block the PCV and get a breatherGT-ER said:Okay...I don't know about forced induccion cars but N/A cars EACH AND EVERY ONE that I have ever worked on has had POSITIVE Pressure, I have seen Negative pressure on only ONE car and he had an intake gasket that was bad, I fixed it a whala..perfect....Hell, the name of the system is POSITIVE CRANK VENTILATION..It's for a reason don't you think.![]()
BTW- as I stated, I have never worked on a forced induccion car so I don't know if the rules change.
