I'd like to keep my Miata and turn it into a track rat, maybe even spec series.

I'll admit I'm concerned about the IMS/RMS problems. I've read that the RMS can be inspected for oil leaking and measured for play. I guess there's no way to tell if the IMS is about to go, short of pulling the engine apart, or something like that??

The Miata had a crank seal/bearing issue in their 1st year of production. Mazda fixed that quickly and the engines have been bullit proof since. I'm surprised that Porsche has let this problem go on for so long.

I hate to rehash this topic because I'm sure most of you are tired about explaining it. In my searches, I haven't seen what percentage of owners that have experienced the IMS or RMS problem. Do you think we're talking something like 1 or 2%?
