Only one cylinder, the one with the spun bearing, looked bad. At the time it happened there was around 0 oil pressure, it had nothing to do with the pulley and everything to do with no oil pressure.
what is it with the h22/h23 motors that make the unorthodox crank pulley mess up all the bearings... it seems that the b-series motors are doing fine with aftermarket crank pulleys... is it just because the h22/h23 motors are larger? why is it just preludes? or is it all cars and i'm just not informed?

It will happen with all cars that have a harmonic dampener put on the crank pulley. Most of the guys dont know what is going on and the problems never get related because most guys dont do engine tear downs and dont believe the guys that have a background in what they are talking about about the damaging effects.
