I have a 98 pcv system and I just got center bolt valve covers for my new heads. The PCV fitting is differant on the driver's side from my old perimeter valve covers. Do I need the 99 and up pcv system or can I get a fitting to adapt?

 

Why didn't you get the LS6 valley cover setup??? I will check to see if I still have my old setup. I switched when I rebuilt the motor. You can have it if I didn't throw it away...

 

I ran into a similar problem when I recently installed my TEA heads on my 98'. On my old valve covers I had a PCV connection on both valve covers plus a second port on the passenger side valve cover that connected to the throttle body. The new valve covers only had one pcv connection on the drivers side and no connection on the passenger side except for the front port that connected to the throttle body. I did not see any way to use my old PCV hoses so I just bought a plug for the drivers side and followed jmX's instructions for installing a LS6 pcv system. It was very easy to upgrade and only cost me about $60.00.

 

Doesn't the block need to be ground somewhere for the ls6 system?

 

Yes, but if you have a dremel it only takes 10 minutes or so to do it.
