In the late 60s an SCCA championship was won by a 911 race team that received no help from Porsche motorsports whatsoever. The stock 911 was entirely reworked by the team engineers. When confronted by this fact, Porsche told them that if they hadn't won, somebody else would have. The problem w/ oil ingestion is an inherent design fault that occurs regularly under known conditions. It does not affect enough cars frequently enough, nor its it so debilitating when it does occur (i.e. RMS leak or porous cases) that it forces Porsche to act (while never explaining/admitting/apologizing) . Porsche doesn't care about your smoking engine, on or off the track. It can be fixed just like the 911 chain tensioner, pop-off valve, case studs, flywheel, valve guides, and a whole plethora of minor to very serious problems that 911 owners have had to suck up since 1965. In fact the US 1977 911 engine was so plagued w/ big time oil leaks due to EGR temps and case stud failures it is considered the worst 911 flat six, ever, a 911 to be avoided. If the rules are too harsh, the game too difficult, the cost too high, don't play. That's Porsches philosophy. They haven't gone broke yet, have they?
