I have a problem with my '89 Buick Century with a 2.5 four cylinder engine. This is the famous "U" block.
About 8 months ago, the car started making a vibration sound, which really sounded like it was coming from the dash. The car is getting old, so I didn't think much of it. The vibration would start and stop at any time.
Well today, I took the car on the interstate, and the vibration got REALLY LOUD.
Again intermitant, would vibrate loudly then stop, the start again then stop.
Pulled the car over, checked the oil. Oil dirty with 4,000 miles since last change, but full.
Vibration start and stop at idle, with acceleration and at highway speeds.
Car seemed to have full power with the motor, no missing or poor idle.
So, I was thinking that I had a bearing going out on the AC compressor or the tensioner.
Oil was full and it had normal power in the motor, I decided to drive it home. On the way, at 75 mph, the oil light came on the the motor died.
Car will restart, idle, and drive, with loud vibration noise but the oil light stays on. Also pulled the dipstick, oil again still full but smelled faintly 'burnt'. No loss of oil either.
Where do I start trouble shooting this problem? Any ideas on what the problem could be?
By the way, car only has 92,000 miles and has been taken care of, not hot rodded.
Thanks in advance.
