Hi all, My Seight is running a TVR 4.0l V8 on a Edelbrock 1404 4 barrel carb with a Offenhauser inlet manifold and K & N pancake air filter. The Rocker covers are both vented to atmosphere with no pipe to the carb vacuum. Having had the car set up on a rolling road I noted quite a lot of oil smoke from one of the vents at full revs (has an after market filter on it) due to "blow by" and I'm thinking of connecting one of the rocker covers to the carb either via the air filter or to the PCV vacuum pipe at the front of the carb. I'd use a standard TVR flame trap and a pipe into the bottom of the pancake filter as first choice as this seems to be the least likely to mess up the carb settings. However I'm toying with the idea of connecting to the PCV as I understand you get a better vacuum and therefore less oil leakage. Questions are:- Does anyone have any experience of this? pictures would be great and even part numbers, sources etc. And do I need to fit a PCV valve in the second option as I'm not clear if one of these would have been fitted as standard, is it therefore needed? Any thoughts or recommendations gratefully received. Cheers Dave
