AndyF--------------------------------------------------------------------------------------I posted about how I liked your clear valve covers that u use for testing. I used 3/8" and 1/2" lexan for my clear valley cover. (I messed the first 1/2" one up w/ carb cleaner) remade it w/ 3/8" and am careful to not spill any thing on it, or be wiping around on it, w/o it being dustless. So far, no discoloration. What brand valve covers did u machine out to build yours , and what clear material did you use to make them? The clear is great for watching the excess oil escaping from around the lifters!" LOL, and watching the condition of the oil . bob
