That'll take hundreds of thousands of road miles to sort out.

I still think the best bang for the buck is to put a Raby upgrade into a roller.

We know when the 987 was released the RMS was still present and being reported by the auto mags when the first cars were delivered. Between IMS and RMS that probably accounts for the vast majority of all critical failures.

Well the RMS is fixed and there is no IMS. Cars have been out for a year. I havent heard of any real issues yet. I would guess that alone should give us reason to hope for a more reliable engine.

I should hope so otherwise the crank doesn't go outside the block!

Specifically the one issue you hear about and that many brands that have gone to DFI have had ...soot. Haven't heard of a catastrophic failure yet though.
