I'll repeat what I said pages ago. Peace of mind while driving anywhere beyond the driveway can only come from biting the bullet, pulling the engine, thoroughly flushing, cleaning, inspecting, and reassembling. YOU can do it mostly yourself .. it's not brain surgery. This forum is a rich source of rebuilding help. Also my 2 cents. Good luck.
