How hard is it to get a new engine from redcat?

two weeks ago,i started seeing metal shavings coming from the glow plug hole.
this made the car shut off randomly and the pull start was stopped working.
today..i pulled the engine out,took the backplate out and noticed more shavings.

cleaned everything up,sealed the backplate and went outside to start it.
the truck started fine but while i was tuning it..the engine died again and the pull start became very hard to pull.

should i expect any issues getting a replacement engine from redcat?

btw..its a caldera 3.0<br type="_moz" />
