I brake torque to 1800 to 2000 rpm'* (car seems to drag a little higher then that) Valve Cover breathers do the same function that the PCV Valve does. It helps relieve pressure from the crankcase. Most newer setups use a breather filter in place of the PCV Valve but I noticed that there are valve cover breathers you can buy for the 3800 so I opted for this instead. The ones I saw for the 3800 where kinda pricey at 30 bucks so I got a universal one from pepboys for 14.
Hey its cool, Im still new at dealing with the 3800'*. This is a whole different animal then the engines that ive dealt with in the past. But Ive always wanted a 3800 powered car and couldnt be any happier with it
