I would check the crankshaft bearings. Like the last poster said not to expensive to replace an can save a more expensive repairs later. Have you done oil analysis on this engine before? Gives you a good idea on the wear metals an the condition somewhat off the engine. If there is an excessive blowby the oil aanalysis will let you know. I think 5000 hrs is a good rule off thumb to check the crankshaft bearings.
