Well I joined last week. 5 Laps into the first of two trackdays. Everytime I read about somone doing this I always ask why? So I think I have some answers now. In my case it was twofold. I have a Falicon super crank and crower ti rods. On first check during assembly I had .0028 inch clearence. I wanted .0025 or smaller. I have been told you can live with up to .003. So I did a dryfilm coating which is supposed to be good for taking up .0004 in clearence. David Vizzard who writes for Popular Hot Rodding and is the author of many books says the coating give more longevity but is not sure why. So I wanted to give it a try. I was going to take the engine apart this winter and these two days were to be the last time I ran it this year. I aways cut my oil filters apart to look for metal and also the magnetic drain plug. The motor had 23 superhard trackdays and about 3k street miles which were hard miles also. I am running 14 to 1 compression there are no signs of dentanation and no oil in the airbox and no sign of any oil in the combustion chamber. Valve guide seals are good and ring seal is perfect. No wheelies and synthetic oil from new. Now here is the interesting part. Every picture I have seen from other peoples rod bearing failure there is heat damage. Mine has none. The parts are all shiny clean. The crank journel is scored as are rod big ends but no sign of any heat. Just worn out. One bearing was spun and the other was down to the copper but in place. So what does this say? My motor was just worn out and needed a shorter maintance schedule. The overheated parts I have seen pictures of would say that there was a interuption of oil supply. Oil is what cools the bearings. No oil and heat is the result. Mine failed, but there was a oil supply at all times and no over heating. My ti rods can be resized and the crank journel welded and reground. Its a $400 fix and I keep my good rods and Falicon crank.
