Breather placement
 

I'm going to be drilling my gm performance valve covers this weekend for my breathers. I bought a billet specialties breather w/o pcv for one side and another with pcv valve for the other. Is there any particular place to put these. Does the pcv need to be on a certain side? Do you offset the breathers with one towards the rear of the valve cover and the other side with towards the front of the valve cover. Or can I put them both towards the rear? I thought I read or heard that this matters do to engine torque.

no it doesn't matter,
put them wherever you want
I'd put them both towards the back, but that's just me...:cool:

no troy.

If the valve covers do not already have them, try to install some kind of baffle at the hole so oil does not splash directly into the opening. Without a baffle oil can get sucked easily into the PCV hose due the vacuum there as well as splash onto the inside of the breather and drip.

Hope this helps.

I would also try to keep it out of alignment with a rocker arm oiler. A breather catch can is the best. You are going to get an oil mess out your breather on the valve cover eventually.
