I'm not sure how you are directing your message, either to me or just in general (with my message just sparking the discussion :) Breathers: All my hi-perf builders insist on 'em. Fye, you wanna elaborate? I have my after-market case breather piped in to the top of my carb, not directly to the atmosphere like most do. Chrome: You're preaching to the choir, my brother :) The only chrome you'll find on my engine is the top of the carb cover. The inside of my valve covers were blasted as well. The only shiny surface on the covers is the S/S hose clamp holding the hose on the breather barb. We had long discussions about this a couple years ago and I'm a firm believer of no shiny metal/glossy paint in the engine compartment unless necessary. My engine is rather boring when it comes to the good-looks department. I understand enough about physics and Jim A. is just an email correction away if I stray :) Bolt-on Valve Covers: My preference, just like electronic points. Yes, stock is perfectly good but -- amazing as it may seem with modern technology -- so are some of the after-market items. VWs were not engineered to be bored and stroked to 2006cc and put out over 140hp but mine does so not all the rules apply :) Toby Erkson air_cooled_nut@pobox.com '72 VW Squareback 1.6L bored and stroked to 2.0L, Berg five-speed '95 VW Jetta III GL 2.0L, P-Chipped, Jamex sport suspension Portland, Oregon, http://www.icbm.org/ >-----Original Message----- >Why do you need breathers on your valve covers??
