Notice some metal fillings in my oil filter when I noticed the engine had gotten a little louder. Decided to tear it down when my dealer said it would be a minimum of 6 months for a crate engine. Pulled the engine out and tore it down. Found a bad crank bearing. Replaced all crank and connecting rod bearings. Put it back together and she runs again. Big job. Found bearing from King Bearings. Engine is so much quieter. My wife is happy it's fix. She didn't see me for a week.
