We all know its your first time. You told us. It's also kinda funny how you completely misse the part about ignoring all the good info. So you've got a blown top end and your mechanic said you did a good job taking it apart. But now its apart and you have know way to tell if the crank seals are good or not. So now you either tear it all the way down and replace all the seals, put it back together and test the seals (then tear it back down if it leaks), or just run the shit out of it till it grenades again. Good times.
