Bought a nytro with mcx 270 kit last week.
The first 10 minutes i had it it threw a rod and piston through the case.

I have a new engine waiting to be put in but im wondering if I need to flush the oil hoses and tank before?

The engine stalled right away.
 

I would. Why risk it?
 
Defiantly!!! If there is metal debris in the lines, then you are introducing that metal into your new engine.
Use brake clean and a little compressed air. Keep flushing until clean.
 
i would clean it with diesel fuel. it lubricates and cleans good enough, and is neutral to rubber gaskets
