just pull your motor, pull your tranny put it on a engine stand, pull the oil pan, check which rod it is if it is a spun bearing, unbolt the bottom of the rod casing, and check the journal for any scoring, anything unusual, just compare the one with the spun bearing to one without a spun bareing. if its scored or any big noticible difference take your crank out and bring it to a machine shop and explain what happened and what you need to be done.. and who ever said shoulda gotten a RB25 STFU. RB20's are good motors, there fun as hell.. and can take one hell of a beating. my .02 is this isnt your fault. its the person who had the car before you, didnt tell you to change oil or how long its been in there.. call him and ask when he got his oil changed.
