I've got an L67 (with 4T65E-HD) from a junkyard, I took it out of a 2000 Pontiac Grand Prix. Odometer showed just over 210K miles, the body was a decent shape, it wasn't in an accident so I'm suspecting it had engine or transmission issues that led to its residence in the junkyard. I won't be able to get it installed in my car to test it within the 30 day warranty period. So I want to tear it down a bit and get a better look at the internals. I'll take off the S/C, the heads, probably the oil pan. I'd rather not do a *full* rebuild, so what are some problem areas that I should pay special attention to here (aside from the obvious, cracked pistons, bent rods, etc)?
