my 2002 black s2k blew a valve as i was accellerating onto the interstate around 8k in third. i bought a used engine and replaced the old one, adding a new stock clutch, and the car is once again a blast. we took the old engine apart and found that a valve had failed scoring the piston, and the valve seat/rim whatever and scratching the cyllinder liner. otherwise everything seems fine. i am thinking of selling the parts of the engine or the entire thing but don't really know what it's worth or the best way to sell it. In perfect condition are the stock intake and exhaust manifold, harness, cams, and probably much more. I would appreciate advice and am also curious if anyone else had a similar failing. i have not raced the car but drive it enthusiastically, including one chin event at Sebring. My Honda dealer accused me of beating the rev limiter but that's not what happened.
