If you pull the caps, spend the $ (not much in the big scheme) and install new Nissan bearings. The crank journals are incredibly hard and even if you have "lightly" spun a bearing (dented oil pan!!!) the crank journal surface is most likely in good shape. Last time I tried to buy plastigage in the range that cooresponded to the Nissan factory clearances, I had no luck, but that was at least 7 years back, so things may have changed. On my Dad's SE-R (engien still in car) I pulled all for rod caps, pushed the piston up the bore and then measured the crank journal with a dial caliper. They were ALL within spec of the FSM. I visually inspected all four journals and compared them with the corresponding bearings that I just reomoved. Even the journal with the spun bearing looked prefect (thought he bearing had surface scuffs along witht eh tangs being all flattened out.... I coated the new bearings with assembly lube, torqued to spec, pounded the pan back into shape, reassembled... The car has 50k additional and still running strong. If this was a hot turbo engine or a race engine, I would pull the crank and do a more thorough inspection, maybe have the crank repolished and then checked for size.<BR><BR>Erik Halvorson <BR><BR><BR> <BR>

<DIV><FONT face=Arial size=2>Yeah I have both pans and both oil baffles already removed. I went ahead and put in the ES motor mounts I had been putting off once I could not find any visible confirmation of bearing failure and called it a day. I am leaning towards replacing the bearings and putting it back together, but was wondering if I pull the bearing and it's ok is it safe/smart to put it back in or once it's out it needs to be replaced anyway. Any opinions on the Cleavite 77 trimetal bearings vs OEM Nissan ones?</FONT></DIV>

<DIV><FONT face=Arial size=2>On a related not has anyone had luck repairing the crack in the primary joints on a HS header? Is it just a matter of time till it cracks again? Does Greg V still deal in OEM Nisan parts with his new business, I don't think he's on this list anymore.</FONT></DIV>
