Mkes sense. So, do you just take the chance that a came lobe could wipe and there are leaks? Am I to believe that there is a low risk of those things happening? I'm new at this and don't have lots of $$$ to throw at a rebuilt engine to fix whatever may have been damaged. with the article in mind does it hurt the engine to do the 20 minute run in then do the "hard" breakin??

Thanks
