So much for the big bore stroker. The valve lash adjuster was a red herring. I fixed it and there was still a lot of noise. Also I noted oil dripping from a crack in my right header collector. This engine had 2 days on the dyno breaking in and tuning. A seemingly good tune. Plenty of power. Plenty of oil pressure. Run on 100 octane fuel. Ten minutes on the track at MSRH during which it had a lot of smoke on coming off throttle. Upon start-up for qual it had a loud tapping from the right side on the engine. Saturday I pulled and tore down the engine. There was a ton of oil in all exhaust ports and header tubes. There was tremendous damage to the piston skirts as shown. The ring gaps were wide with the first ring at .025 - .028, second at .026 - .029 and all oil rings greater than .030. Having trouble adding images, will try again. FMR
