ok so we tore down an engine last night. oil looked clean. but when we got to the rear rotor the rotor bearing had some copper showing and some chips missing from the bearing. eshaft was slightly dented where the damage occurred .


oil pump is fine, front rotor is fine. oil didnt have ANY copper in it when we drained it. oil pan only had normal catch on the magnetic drain pan plug.



engine had a slight tick/tock noise prior to CAS failure causing engine to blow. after engine blew the engine had a more distinct. never would assume it was a spinning bearing...

idk if it was spun prior to engine blowing. or the engine being blown and having 20 miles put on it caused the unbalance and thus the spinning of the bearing.

we did drive this engine 20 miles after it was blown since we moved to a new house and had to relocate it.

You should at least flush the oil cooler if your worried, depending on what comes out of it may be the deciding factor on if you should replace it.
