255 respondents with the gist of the results being that 40+% of the respondents either had an engine failure or RMS leak. IIRC, the engine failure rate eas 8%.
This seems fairly close to our survey and the one I did with my club with roughly 30% had RMS leaks.
The older cars were more prone to leaks or they just haven't shown up yet in the new ones. However you look at it, an inordinate number or cars have had this problem despite Porsche's attempts at a fix.
