Noise

:ph34r: Is It my imagination or is the Nortstar engine noisy.

I have had Fords that you couldnt hear running.

When I go to a drive in teller you can hear the noise bouncing off the wall sounds like valve tappets. Recently went to the stealership and they said it was the AC compressor . Still have the noise, specialy on a cold start.

I have experienced that you described. I never hear any clackity clack unit I pull up at the bank drive up window then I can hear a lifter sound.

Personally I think that engine noises reflected off a wall toward your ears are magnified... I never hear that noise any other time. I wouldnt worry about it. Maybe its time to change the oil, who knows, im down to 12% :lol:

Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home. Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life.

General Motors A/C compressors have always been a little noisy in my opinion. Mine ain't any different. I can easily hear a "clackity clackity clack" sound in a drive-thru or bank teller line (or anytime the car is stopped) that goes away with more engine speed. It also goes away when you turn the A/C off. It's definitely the compressor. The bearing has been replaced once on mine. I don't know if this is a failure mode for a compressor bearing or not. Anyone know for sure? Is it a high-pitched clack or a high-pitched whine, or a low-pitched whine, etc? Mine's been doing it for years...never paid much mind to it.

As a point of reference, I have my AC compressor by-passed so my clakity is not coming from it..

GUYS......What your hearing is not valve lifter noise.

Your hearing fuel pumping thru the fuel rails and injector

I had issues with my 01 & 04 Chevy trucks and "lifter tick" at idle.

(NOT to be confused with "cold start knock"!)

A smart tech at the shop whipped out a "stethoscope" and let me

listen and probe................SHO' NUFF !!!!!!!!!!!!!!

Most big box parts stores sell them for about $8 bucks...........geo

That sounds about right geo....I am sure the hard cold flat reflective concrete wall magnifies the sound. That is the only time I hear the noise, if I lift the hood its not there. It sounds like the oil is low..

Funny to see this thread. I was putting air in my right front tire this evening with the engine running, the AC on, and my head nearly in the fender well when I thought to myself, "Darn this thing is quiet. What a SWEET machine!"

Maybe I'm just lucky (or deaf)??? :D:D

The alternative is only whether the crisis should come sooner as the result of a voluntary abandonment of further credit expansion, or later as a final and total catastrophe of the currency system involved. - Ludwig von Mises
