Engine Overhaul

  Dave Groh and his staff of A&P certified mechanics specialize in overhauling Continental W-670s and Wright 760s (Whirlwind J-6-7s).  There is a lot of work done as part of a Yesteryear overhaul that you might not get other places.  All engines are line bored with new bearing liners, and every part is inspected and measured to ensure that it meets the new part specification and not just a serviceable limit.
