what do you mean tsb's or anything?
hard breakins dont work? supporting details please?
you are telling this to a guy who has broken in all my engines that way.
there were no symptoms, it happened really fast. i was a few blocks from home, engine lost power and started to vibrate. i shut it down and coasted home. tried to start it, it did not kick over, sounded like a dead battery. tried 15 mins later, it kicked over and i heard loud banging, and from experience, i immediately thought connecting rod. boy was i right |
TSB = Technical Service Bulletin.
It's a list of common failure items on a vehicle or particular things for a mechanic to look for. Like, noise coming from front right, common failure noted is defective driveshaft or something. Very handy when shopping for vehicles.
Just google 2013 Scion XB TSB for example to see what I mean.

FWIW, I don't do hard break ins but I'm not easy on them either. Plenty of people do short dyno break ins on motorcycles and then take them to the track. I wouldn't flog it but you don't have to hold back. Every vehicle I've owned new or rebuilt the motor for has been driven like that. I get ya.
