the rec. is to break it in for a thousand miles i drove it under v tec for 3000..so yes i broke the engine in...also wen i took my motor apart there was no indication on the cyl walls or the pistion it self to show burning of oil..but there was excessive oil build up on the back of the ex valves...also wen i pulled my pistons out i noticed oil build up just above the `1st compression ring and only on the ex. side
