What does the PCV system look like on your vettes? My air filter and rocker covers are not original and I have a tube running straight from myPCV valve into my carby, now on most cars iv'e seen (including my Niki) theres is like a metal shavings filter between the rocker cover and carby that traps airborne oil particles which collects and eventually drips back down into the rocker cover.
I think I need a filter like this to minimise my carbon diposit problem on the plugs. One thats slots into where the PCV valve is now. My question is do I really need that valve? Why is it there? I hav'nt seen one on other cars... unless im not looking properly.
