my friend has a 95 v6 taurus and all of a sudden it started making this clunking noise thats coming from inside the engine it sounds like. it sputters and backfires just while idoling. im thinking the timeing chain. please someone let me know if ya no what the problem is!

:wtf:

 

[stangin99]

timing chain? ummm why do you think that?

 

[mustangmeat]

spun a bearing maybe

 

[tealstangman]

it could have i dont know

 

[Rellik]

check the tensioner pulley or the idler pulley, a bearing is probably gone in it.
And making loud squeals and squeaks.

Try to narrow down where this sound is comming from, like close to the belt, or close to what you know what i mean?

:evil: Have you done any work to it recently? How many miles does the engine have? When was the last time you did a tune up to it? If you have high mileage on the engine the noise could be coming from the timing chain.

I had something like that happen to my old acura. It was the heat shield on the exhaust. Coul that could be the problem :-?

 

[Rellik]

heat sheild wouldnt be that kind of noise, it would be a flapping noise from under the car not in the engine bay.

but you can rip those off. no biggie.

 

[Klamdogg06]

yea thats wut i did...then it sounded like a lawn mower i hate it!

 

[tealstangman]

it has 59,000 miles. recently the head gaskets were changed. i was thinking timing chain to.

 

[Rellik]

ripping the heat sheild off wouldnt make it sound any different. Maybe u didnt rip the sheild off. lol.

it has 59,000 miles. recently the head gaskets were changed. i was thinking timing chain to.

I still want to know why you think its the timing chain.

If the timing chain was on its way out I would reccomend not running the car at all. I know from personal experience how much damage one can do when they let go. :shock:

 

[Klamdogg06]

becuz it will explode into a million gagillian pieces! :shock:

:evil: Did the noise start happening after the head gaskets were changed?
Does the noise quiet down as the engine warms up and does it get louder as you accelerate? I'm not sure if the v6 in the Taurus is the same as the OHV in the Mustang but if it is and the noise started happening immediately after the gaskets were changed then maybe the valve lash was not adj. properly. Also how aggressive has your friend driven that car?

 

[tealstangman]

it started happening after the head gaskets were changed. it doesn quiet down once it warms up. it gets lounder when you accelerate. she's drives it pretty aggressively. :twisted:

 

[widowvirgin]

:evil: If you haven't taken the car back to the place where you had the gasket job done, then you should do it now and let them know that the noise started happening after the gaskets were changed. It's probably something they did. If the noise was IMMEDIATELY after the job was done then they should find the trouble and fix it for you free of charge.
I still don't know if that v6 is an OHV. And are you sure that it's backfiring. If its sputtering then it might be because the valve opening times are slightly off but I don't think it would be causing that loud noise. Also you don't know if the oil pump stopped working and your friend continuied to drive the car. She could have damaged the heads but this is only a possiblity! I'm not saying that this is the problem. The reason I asked you how aggressive she drives the car is because I also I had something similar happen to me with my dads gm. Since I hated the car (its a gm) I raced that weak 4cyl. engine every single day, religously, to and from school. I cruised at 90mph+ and it was a 21 mile trip one way. A month later a loud knocking sound could be heard and it got VERY LOUD as I drove it more and when I accelerated. Turns out that first the oil pump went and the #1 pistons ring was cracked?

95 Tauruses had OHV, according to Edmunds.com

ripping the heat sheild off wouldnt make it sound any different. Maybe u didnt rip the sheild off. lol.

actually mine used to vibrate on my mufflers so i ripped em off. It made an annoying sound... bu not anymore

 

[Rellik]

well yea the sound of it flapping. But he said it would sound like a lawnmower
