This is the worst Evo motor I have taken apart in quite awhile. The owner totally destroyed this Evo motor with lack of oil changes! Without a doubt the top end has already been rebuilt and from what I can tell the workmanship was ok. Just look at the photos and you will see the waste oil in the crankcase. You can notice the spun pinion race on the pinion shaft. When that seized the bearing started walking out the of case and pushed the oil pump drive shaft locking it up in the bushing it spins in. This motor is trash. 75% of the parts are not worth rebuilding. That is not to say the owner will agree.
