I recently bought a used 7MGTE complete just to take apart and fool around with. I was told by the owner that it had 175 comp in all 6, no valve tap, no knock, no blue smoke. Normal 7M oil pressure. All spark plugs light mocha color with no indication of detonation or carbon. 135 K. The valve clearance and condition of the cams is excellent. All main bearings and crank excellent. Clearance is at 1.5 to 2 thou. max. Here's where I am slightly stumped. The rod bearings. Here is what I found. #1 and #6 excellent bearings and crank 2 thou clearance. #'s 2,3,4,5 Visually the crank is machine shop excellent. The bearings are Toyota standard size. The bearings are all scratched and very slightly coppered 3 thou clearance. They were not blue but, you can see where there was some metal deteriation taking place. Also these suspect bearings, although they did'nt spin, would not snap into place on the rod. When you would put the bearing shell in to the cap, it actually looked like they were the wrong bearing for that cap, like they shrunk, LOL. I have never seen this before, and would like some opinions and or idea's. Bottom end of Motor does not appear to have been worked on before, although I was told there is a HKS headgasket on it. Thanks, Joe
