Default Those with Canton LT1 valve covers, inside please...

Trying to figure out a few things:

(1) Does the stock PCV valve and grommet fit in the hole on the passenger side cover?
(2) What breather are you using? If the threads on the oil cap are the same as stock then I can just get a Metco. If not, what are you guys using?

I am pretty sure that the stock PCV valce and grommet fit in the passenger side. I'm in the process of building a new engine and i'm 99% sure that we just went to the auto parts store and bought a stock PCV grommet for it. I think the threads for the oil cap are different than the stock one bc it comes with its own cap. As of now i'm not running a breather there so i can't help you out too much more.

Ok, so it's not the PCV valve but it is a crank case ventilation opening that goes to the throttle body.

No the stock grommet doesn't fit the hole. Go to O'Reilly's and in the help sectin there are grommets. Looks for 42323 I believe, maybe 43232, it will be a tight fit but works great and the ID is the right size for a Fram, Purolator or Duestch filter. After I switched I haven't gotten any oil in my intake, I think it's because they are taller and I'm running a filter now.
