I'm glad I couldn't get my Tuna can to fit correctly. I never did like the idea of losing the oil screen. Here's a good reason to keep the screen - look at all the crap caught by the screen since my last oil change which was less than 1000 miles ago. It appears that most of the stuff is excess sealer used during the rebuild. So what do you guys think? Which is worse, momentary oil pressure loss around certain turns at the track or the chance of some of this contamination getting clogged in the oil passages?
