Buick - Century :: Loud Tapping Noise From The Engine Especially When Cold
Sep 25, 2015
Last month I changed the oil and filter in my 1992 Buick Century with 264000 miles. I used a name brand (Citco) of the correct oil, 10W-30, API Service SN. I bought the oil on sale at a local supermarket. Now, I hear a loud tapping sound from the engine, especially when it's cold. It dosen't sound as loud after warm-up. The tapping increases in frequency when I rev up the engine. I don't intend to keep this old car much longer, but is this problem an immediate concern? Could it be a valve problem? Could it Could I have bought some bad oil with a conterfeit label? Other than this noise, the car runs okay.

2004 Buick Century. 3100 motor. 150k miles... Recently discovered strange noise but not sure exactly how long its been happening. (I listen to the radio pretty loud)
Engine sounds normal at start/idle (hot and cold). During acceleration I hear a constant ticking/tapping/clattering at a decent volume from 1st to 3rd..after 3rd it quiets down a bit but still constant. It goes away completely directly after shifting into 4th. I then cruise down the highway at 75-80 with no problem whatsoever.(It can also be heard if i rev the engine in park.)
The day I noticed it i immediately checked the oil. It was a little over a quart low. I filled it but the sound has not changed.
I wouldn't say its a full on knock but it does sound alarming like the engine could blow at any moment from 1st to 4th. Sounds perfectly fine after that.

I own a 2001 Buick Century Limited that has 208k miles on it. A couple days ago I started the car up at a friends house and noticed that it had a loud rough idle and that the check engine light came on. When I drove the car home, the CEL would flash when I accelerated and I could smell something burning. When I released the gas pedal and coasted, the flashing CEL would return back to a solid state but I could still smell the burning. When I would accelerate, the CEL would start to flash again. Whenever I was stopped at a stop sign, the flashing CEL would again be solid and there would be a loud rough idle along with the same burning smell. Am I looking at an engine replacement or an easy fix? One problem or could it be multiple problems?

I have a 2004 Buick Century with about 48,000 miles on it..the A/C blows very cool but not cold,it should be colder..i also have a 2003 century that blows icy cold.. I hooked up a cheap gauge to the low side service port on both vehicles and got about the same reading. Other then being slightly low on refrigerant is their anything else that would cause the A/C to blow cool air rather then icy cold? The compressors seem to kick on the same on both vehicles. I really don't want to add refrigerant if it's not low...

I am getting a loud knocking noise from the engine on my Santa Fe. The car is very low mileage of around 51K and has regular service and oil change.
Not sure what has caused this but there is a loud tapping/knocking noise coming from the engine. Have got it locally checked with the garage and Hyundai Workshop also but both have suggested that Oil levels are appropriate and they need to open engine to investigate more.
At a higher RPM the sound becomes more loud and recognizable.

I'm having an issues with my Santa Fe MY07 - Basically I was driving down the dual carriage way last week when suddenly the oil light came on and with the 500m it took me to stop a loud tapping noise was coming from the engine as it seized - The break down people came out to the car as they were inspecting it they informed me that the Sump cap was missing - the car is under warranty - however Hyundai as say that because the cannot find out why the sump cap had came off (and that in there mind they cannot give any reason why it should of) it is there for NOT a manufacturing issue and that they would not cover the repairs under warranty...

I have noticed that when the car was in park today right after I started her I heard a semi loud tapping noise coming from the engine... It slowed down when I turned the wheels or played with the brakes... As I went into drive the noise went away after about 20 feet of driving..
What this could be? Is it normal... Just bought the car last week with 45K miles on it and just want to make sure if it is a normal noise or not or whether I should bring her into the dealer.

My 2003 Buick Century heater works fine while accelerating but as soon as I release the gas the air begins to cool, swiftly. I have had the radiator flushed and the coolant topped off but the problem persists.

I've had this tapping in my engine for a few weeks now and I put it in drive then heard a huge bang from the front of my engine and then started making a very loud popping noise that almost sounded like air leaving the valve cover...

I have a 2001 Buick Century that started making a noise from what seems to be the engine. It sounds like a jet engine when I accelerate. The noise is still there when I cruise, but it evens out. It is loudest when going between 40 and 50mph. The car is not overheating, and other then the noise it drives fine. My husband at first thought it sounded like the catalytic converter had been stolen, but he rarely knows what he is talking about. What could it be?

Does this mean I need to see a mechanic. My car is a 97 buick century, 94kmiles. Rear brakes were replaced at 83k and front brakes were replaced at 80k. A few months ago, the noise began and has persisted once a day when brakes are applied first time of the day.

My morning commute is about 33 miles. After about 30 miles, when I almost reach my destination, my 1992 Buick Century makes an additional noise besides the normal engine, muffler and road noise. It sounds like a BRRRRRRR....., but only when the car is moving, not idling. I thought it could be a temperature- related transmission issue. I noticed it was low on transmission fluid, so I added some. It still makes that noise, but only after I traveled about 30 miles. I didn't notice it last year when my commute was only 16 miles. What could cause it?

I have the GM shop manual and I have gone through the flow chart for an engine which cranks but does not start. I have confirmed that there is fuel pressure and spark, but the injectors do not fire when cranking. I have gotten to the final troubleshooting step of disconnecting the crank angle sensor connector, jumping A and B terminals on the connector, and momentarily grounding the jumper with a test light. The injectors fire as confirmed using the GM injector test light (in place of an injector). The flow chart conclusion is that the crank angle sensor is bad or misadjusted or the connector is making a bad connection. I have replaced the sensor twice and adjusted it using the GM adjustment tool. The connector terminals appear clean and undamaged. 1989 Buick Century 3.3 liter ...

A couple of weeks ago my 2005 Buick century start making a noise when i hit the brakes and all the lights on the dash lit up like a christmas tree. The noise it makes when i hit the brakes is like humming sound and the pedal will get kinda spungy and push in and out, if i keep driving it stops and all the lights come on (abs, trac off, service engine, and sometimes the brake light as if the parking brake is on) after all these lights come on the noises stop and the brake pedal works fine. I was told that the anti lock brake pump was going bad but I didn't realize there was a pump.

1996 Buick Century has a humming noise while driving at normal speeds and curving or turning slightly to the left only. It will not do this while turning left from a stop or slow turn, but only at moderate or hi-way speeds. You can make the sound while changing lanes, passing or curving to the left. This is only noticeable on actions involving left turn or merging motions.

Buick Century 1987 - 2.8L
Sending unit measures: Empty 9 ohm - Full 88 ohm
Fuel pump working while engine is running or key switch in ON position (working properly).
Issue: Fuel needle fluctuates while car is in movement and the engine stops when the car is going downhill and suddenly is braked (half tank), Is normal this behaviour in this car? Is this car equipped with a 'anti-slosh module'? if yes, where it is located?

I had this problem a few times in the past. Sometimes my 1992 Buick Century will shut off for no apparent reason while idling. When I restart it, the engine will race for a few seconds before slowing down to normal idle speed. Could this be caused by a glitch in the car's computer?

The car died on me the other day at a stoplight but started up again (It resisted for a sec but then caught). Now it's taking a bit to start and sounds very faint when it finally catches and the turn over is slow. I'm no mechanic but I can replace parts. I'm just wondering if it's the fuel pump or injectors, maybe low fuel pressure. I haven't had a chance to do anything to it. Where to start?
