RE: Didnt break in my engine
When you replace the piston and sleeve, it wouldn't be a bad idea to replace the con-rod and wrist pin as well.
Not breaking it in properly puts quite a bit of extra stress on the con-rod, and that could cost you your piston and sleeve at any random time.
But yes, a rebuild will fix the didn't break it in blunder if you replace the con-rod, too.
...Unless you ran it so lean and hot that it fried the crank bearings...
