I agree with them, I pulled side cover off that was leaking to my surprise not much carbon, then that lead to oil pan leak that needs gasket, then looking up into everything looks fairly clean. Just hoping the rear seal is good I'm not planing on pulling transmission. Bottom of oil pan had less than 1/2 inch of sludge in it with possible very fine metal dust. She smoked a little on start up but is running just fine. Just thought I'de share.
