So whats the history of the car?
Are you the original owner?
Are there any mods if yes how long have they been on the car?
By reading S2000 forums there were cars less than 2 years old stock loosing bottom bearings, the solution was to go with larger clearances.
Most engine builders are using the max clearance .002".
If you rebuilt with stock clearances I would seriously rethink that and redo the bearings with more clearance, but that's just me.
With having problems with the bottom end bearings I would give more clearance.
Acl race bearings at .002 clearance is what the builders said I read this morning.
This is just a Google opinion I have no experience with this engine.
I cant see the Moly causing this. Just my opinion.
Shannow is a bearing engineer maybe ask him if he has seen or heard any Moly related failures.
