Vytas, I definitely respect the mechanics at Los Gatos when I talk to them directly...they seem informed and competent. But my service advisor definitely didn't have his facts straight at the time. I can understand that they want to protect themselves, but the 3.0 comment made me feel that they're flailing away from anything other than assembling a new engine for me -- which not only is MUCH more expensive, but probably riskier from a reliability standpoint than a used engine. Hopefully I can get a final answer from Hopkins Acura, who is graciously contacting an NSX production engineer for me to determine what the risks/difficulties are, if any, to putting an '01 in a 98.

What happened? Can you talk about it ?
My 98 engine, currently at 42K miles, had a rebuild done by (shop omitted for now) at about 25K miles due to a spun rod bearing caused by low oil (previous owner neglected the car). About two weeks ago during normal driving I noticed a slight coolant smell, then a few days later the car rapidly overheated and blew steam/white smoke from the exhaust. Towed it to Los Gatos, where the heads were removed after a coolant pressure test showed leaking head gaskets. The seemingly-intelligent mechanic showed myself and my engine-handy friend all the problems: Most of the head bolts were stripped (they came right out). Improper torquing is suspect since the heads weren't warped. So the block is practically unusable due to the stripped bolt holes (you'd have you helix an awful lot of them to try to bolt the heads back on). One head is quite damaged due to a misaligned cam
grinding into the head, and there's evidence that that cam was installed improperly from tool dings in the head. Some of the cylinder walls have lost the cross-hatching, which happened during the spun rod bearing incident, and apparently never resurfaced by (shop omitted for now). The pistons, rods, and crank and one head are probably still good. Everyone is suprised that the car ran for 17K miles since the crappy rebuild, and I'm suprised how well it ran.
