Never had any problems with stock parts and 10,000 RPM. Mazda couldnt understand how they stayed together. It was the oil, but they never believed me. If I ever got the oil too lean it would warp the apex seals every time. And thats the same problem with the 8's today, and they still dont believe me. The only difference is the apex seal is so much smaller it will at least get back some of its orginal shape after cooling back down. The old 1974 seal would warp and it was over! What the "smart" people dont understand, is the apex seal overheating is comming from friction heat. The seal against the rotor housing without proper lubrication creats a lot more heat than the combustion heat. And the friction heat never goes away.m Thats a plus on av gas having lead in it. It helps lube apex seals. But sucks on fouling plugs! ----------MailBlocks_8C7FAE7D3C1BBE7_B78_1352D_FWM-R09.sysops.aol.com Content-Type: text/html; charset="us-ascii"
