2003 Buick lesabre ticking noise

Just Bought a 2003 Buick Lesabre. Soon as I got home with it I noticed there was a loud ticking noise under the hood. Seller just changed oil so oil is clean. Is this an expensive problem with the engine? Could it be thr hydraulic valve lifters? What might be an approximate cost to repair? The car has 88,000 miles on it. He said he would fix it or give me my money back! Not sure what I should do! Would you please advise?

I would take it back. If camshaft is damaged, it will be expensive fix. Lifters going bad at 88k indicates neglect.

You have to take all the facia off the dash - and then pull the dash cluster out. It is a long hard job for a light bulb. When you take the dash out don't forget to undo the speedometer wire and then the wire plugs on the left and right upper sides of the dash unit.

Yes there are struts on the front and shocks on the back. 2 of each. They are around $50-100 for the fronts. $30-100 for the rears depending if the car has air ride or not.

SOURCE: 95 Buick Lesabre bucking

Had same kind of problem on my '96 with 254,000 miles only it finally got to where it was not driveable at any speed. Ended up being the fuel pump in the gas tank. You've gotta drop the tank to get to it. You'll need to make sure you clean the accumulated rust and other crud out of the tank. Suggest replacing the pump AND the screen AND the fuel filter while you are at it. All together, the parts ran me about $160.

SOURCE: where is pcv valve 1998 buick lesabre

Remove the sight shield from the fuel rail. (it's the large plastic shield that dresses up the engine) As you stand in front of the car the alternator is located on rear left side. In front of it is an electrical connector to the MAP sensor. Remove it. Press the PCV valve cover down and rotate it 1/4 turn counterclockwise. It is actully on the intake manifold. Lift the cover, the upper O-ring and the spring from the housing. Remove the pcv valve and the lower O-ring from the intake manifold.

The instrument panel switch is making a ticking noise in !y 1992 Buick lesabre causing the headlights to stay on...killing the battery

Is the noise actually coming from the switch area or coming from under the dash area? Possible daytime running light /twilight sentinal modual shorted out causing your issue. Unplug this module and if the headlights go out,this will be your problem

2003 Buick Lesabre Custom Need to change the fuel filter, but cannot find the fuel pump relay to remove the fuel pressure. Relays under the hood do not list one for the fuel pump. Any idea?

You can release the fuel pressure at the fuel service port on top of the engine. Be sure the engine is cold and you hold a good rag under it. No need to remove relay if key is off.

Noise under hood

Its likely your catalytic converter's heat shield that has come loose due to rust. Raise your car, and thread two or three large pipe clamps (the screw type) together. Wrap this assembly around the catalytic converter and tighten down. Hope this helps. Bilal Hassan Clarksville, MD

The problem I posted earlier is on a 1996 Buick LeSabre.

two things it would be 1 your battery could be bad even if it is not
dead and will start your car it could have a bad cell
the other thing could be the belt is loose and not letting the alternator
spin fast to charge the battery so it slips on the belt but thats what the noise is the belt check the battery at autozone for free
and if thats not it its the belt
