19 year old took the lesabre to the mall other day,he called and said the engine is making a weird sound,told him to bring it home so i can look at it,i pulled it in the garage and pulled the oil pan off,just what i thought a rod bearing was bad.i pulled the old bearing out and bought a standard size new one but it was to loose,i am going to try an undersize bearing maybe .020 or .030 to tighten it up the 3800 has 125,000 on it i am surprised this happen the oil was always change at 3000 thought the 3800 was unbreakable guess not.
