aftermarket valve cover help
My 2006 sierra with a L33 engine suffers from bad valve covers which are letting the PCV suck up a ton of oil. I want to switch out the valve covers and I was thinking of going with some after market ones. My question is this: I have yet to find a set of after market covers that have the PCV tappings in them.... What do I do with these valve covers? Are people just not running a PCV valve anymore? That's not right... So what am I to do?

Thanks for the help guys. I have put on a catch can but I have to drain the oil every week. I get a good 1/2 quart every Sunday when I drain it. If I forget, then I get the smokey oil cloud at start up on Monday at work.
Mine is the fixed orfice type. I think I have been reading that it is a problem with the baffles or the return holes in the baffles are plugged. I could just replace the valve covers with new GM ones but I was hoping on using a cooler set of after market ones. There in lyes the problem... none of them seem to have the connections for a PCV valve or any venting for that matter. I was wondering how others are using these valve covers?

I replaced the drivers side valve cover yesterday. I did not notice anything out of the ordinary under the old valve cover when I took it off. The valve train was clean and no sludge or gunk at all. I could not tell by looking if the oil drains in the baffle are plugged or not. I am going to run this new valve cover and let you guys know if I stop blowing oil from the PCV setup. Hopefully the catch can stays empty!

catch can still empty
It has been five days since I changed the valve cover and the catch can is dry!! Looks like the old valve cover baffle was letting oil by for some reason. I will post if I notice a change or find out why.

I'm like 30k miles since I changed mine without a puff of smoke.
