Weird noise coming from engine bay.

[slowchevy]

As odd as it sounds, it sounds like someone putting a plastic drinking glass, open end down on a counter.. don't know how to describe it other than that. Only happens when the car is idle.

Happens at the following seconds in this video, gotta turn up your speakers.

0:02, 0:03, 0:07, 0:10, 0:14, 0:15, 0:18.

For what it's worth as well, I've heard lifter knock, valve tapping noises, piston slap, bad main bearings, bad rod bearings..this stuff does not sound anything like that.. I'm kinda confused. What else could this be do ya think

Really hard to tell from that video...... Some ideas for you:

Backfires out the exhaust. These can make strange noises as depending on your exhaust setup.

Failing evap. solinoid. Now that it is in the 60's outside, it should be cycling..... It is on the front of the manifold... Unplug it to see if the sound goes away.



If you have a way of posting a better video, maybe with the hood open to unmuffle any sounds. Try to listen and narrow down an area. Of the engine/engine bay

Take the shotgun to it already.

The sound is coming from near the manifold area, nearer towards the firewall when the hood is open.

Exhaust is stock manifolds into a 3" ZZP Downpipe with Magnaflow cat to a stock cat back with the exception of a Magnaflow resonator.

Isn't the evap solenoid vacuum controlled? If so, a piece of vacuum hose broke yesterday while I was cleaning the engine compartment and that could easily explain why this just started happening I think.. Here's how it looks now.

It broke and I reinserted the shorter piece anyways, but if you think that could fix it I'll run over to the JY and grab a length of the stuff tomorrow along with the new rubber piece.

Take the shotgun to it already.

You wonder why I say some straight up nasty shit to you , a la your signature.. this bull shit is why. Instead of continually running your mouth to me maybe you could be helpful. If I could afford a new car, I'd end up with something else. I can't, so I need to fix what I have. Grow up.

Actually, upon reading.. A goes to FPR , B to EVAP Solenoid.

I'll know tomorrow for sure

Well, the car runs smoother now and has a few better MPG but the noise still exists.

Prodded around a bit with a screwdriver like a stethoscope, the alternator seems to be the culprit.. back side bearings are starting to make noise.

Either way, free lifetime warranty on the part from Auto Zone. Looks like that's my project tomorrow

 

[Lord Tin Foilhat]

easy job! get r done!

\Auto Zone.

This is the problem. I know I worked for Napa but most every gearhead knows to stay away from there for hard parts. Theyre fine for oils and cleaners but everything else is junk.

The only reason I'm going back is because the original replacement alternator came from there

Good luck getting a replacement. If it does not test bad on the machine they probably wont give you one.

I'd drive to the store and let them hear the noise with a stethoscope while it is still installed on the car.

 

[Bob Kazamakis]

I'd leave it on the car and let them hear it for sure.

 

[slowchevy]

they've exchanged for me before for the same issue on the first replacement alternator. will drive there anyways.
