Suspect crank and fretting cases are only usually found on engine stripdown, followed by a further delay in getting back in the air.
Still say a call to airpart and quote for a factory rebuilt engine is a no brainer,
Engine arrives, 1day to take your old unit out and fit new engine, send your old one back in the box. Most engine shops take 2 to 3 months to turn around, add the cost of insurance and Hangarage to it, plus the 2 year warranty 👍
