Wierd noise from engine...

[adamzan]

I have no idea what it is, but I'd REALLY appreciate anyone giving me any ideas, my friend thinks its the a/c idler pully, because it has a little bit'o'play in it but i don't know.

 

Normally I'd find out what the problem is but I have a midterm tomorrow and can't have the pathy all apart tonight.

I found it hard to tell honestly - waht was it I was supposed to hear, the intermittent clicking? Hard to tell if that wasn't the camera....

 

Describe in words what you hear and when you hear it.

Yeah thats it, and when i rev the engine it gets faster. It runs and drives fine though My friend was listening to it, and he thought it was the a/c idler pulley or the power steering pump...or one of those belts. But I have no idea. I'm really not good with mechanic trouble shooting, but if i knew what it was i could fix it.

 

Ignore all the other...bad noises....

didn't sound like anything out of the ordinary to me...Possibly that lil plastic piece under the fan shroud is loose and occasionally slaps around?

Thanks, i'll check it tomorrow. I wouldn't be surprised if it was loose, with the idiot who owned it before me

Has it done it since you bought it or did it just start? If it is new, has there been anything strange happen recently? Give us some background.

It did it a little while ago(probably never stopped), but I didn't think it was serious and forgot about it, now that i noticed it again, im thinking it might not be so good. The only thing that i could say is strange is that once warmed up, on light acceleration the engine does accelerate consistantly, but if i give it a little more gas it works fine. I was told that for that it could be the Throttle position sensor going, but there were no codes, but i probably didn't read them right, i'm going to take them tomorrow and see.

 

Other than that, she drives great, the engine doesn't knock, or burn a drop of oil (like i don't add any between changes, and it stays full the whole time)

 

I know i have an exhaust leak, but that is not the sound im talking about.

valve slap? from that vid your guess is probably better then ours.

I think i discovered what the noise was, when i was on my way to school this morning i kept smelling burning, so i pulled over and saw that the a/c belt had partially failed and some of it was wrapped around the fan shaft. I drove to the nearest gas station and borrowed a knife ( i knew i shouldn't have taken it out of the truck!) and cut the belt off. Its SO much quieter now, and i think its more peppy too.

It's peppier of course - you removed a fair bit of resistance (both the A/C compressor pully and the resistance of having the belt wrapped around the shaft) but you will want to replace that when you get the chance.

 

As for the ticking/clicking noise... could be a rocker? I have the same kind of sound on my truck and that's what my father and I figure it to be.

Well its not doing it anymore so i figured it to be the belt.

 

I'll replace it when I do the tbelt next week, or i'll just wait till spring.

might as well throw out there an exhaust heat shield rattling either on the manifolds or down at the cat...but it didnt really sound like that to me
