buick regal 1995
Ahhh…the old Buick Regal. Probably has the 3.1 v6. Am I correct. If it does these engines have been known to have engine noise. Trust me, I had a 96 Lumina with the same exact engine. I didnt have loss of power though. Chances are a lifter broke inside the engine if it sounds like there is something rolling around or being thrashed around. Does the noise seem to calm down any when the engine warms up? Is there anything that makes the engine quiet down? We need a little more information than what you have given.
