Oil every where but not a drop to drink

Hello,
If you have a PCV in the cover, you can expect more oil than normal sucked up into your PCV system. When I put
CompCam roller rockers in my 2002 5.3, I had to modify the baffles on the driver's side. I did get more oil useage.
But that kept the intake valves well lubed!
My fix was to use a Corvete style valley cover and put a second passenger side cover on the driver's side. Using a "T" to connect both covers for the fresh air (clean) intake side of the PCV - valley cover.
So I did not remove the baffles, but made more clearance for the taller rockers.
Hope that helps.

watching many U tube vids....seems the baffles get crud and then clogged up ...with no way to really clean them besides replacing them

and removing them does gain clearance for some rocker arms

Find some valve covers with this type of baffle. Running these with T&D billet adjustable roller rocker arms and a 3/4" valve cover spacer.

Do NOT remove stock valve cover oil baffling. The GM system isn't all that great to begin with. Removing the baffling will make a bad setup even worse. If you need extra clearance, get thicker seals or use cover spacers.....
