25 miles would be 40 KM, not 250. Moot point, it's a new baby just off a rebuild, if it's a 2013.
Very early in the life of a rebuild is when things are most likely to show up that are a result of poorly made or incorrect parts, fasteners not properly torqued, lubrication channels not free of obstruction or oil pump not working properly etc etc etc.
If a builder screwed something up that's when it's most likely to take effect.
Who rebuilt the motor? He/she/they should be the ones hearing this.
