Every morning when I first start-up the I-5= there is a noise that comes from the front of engine area, for a for 5-7 seconds, then the noises go away for the rest of the day??

Anybody else have the same issue?

 

could be the secondary air injection pump

 

How many miles???? Yes, 100s have and will. From a post of mine back in 2012:

"The Atlas Series engine has hydraulically actuated timing chain tensioner that requires the oil pressure to first come up to add the required tension to the timing chain. Over time the chain will stretch, but the tensioner has ratches that will eventually allow it to click over to the next position to correct for the slack in the chain. Sort of like self adjusting brakes worked.

When you first start the cold engine, if the chain is loose and before the oil pressure can come up to take up the slack, the chain may contact the insides of the front cover. It sounds like a rattle that immediately goes away.

What is happening is the chain is loose enough to slap but not yet loose enough for the tensioner to click over to the next position. Not all will do this, but a bunch can for a while. If this persists for a long time, you may have a timing chain that stretched too far, or tensioners that are worn and need to be replaced.

GM TSB 06-06-01-017G covers the revised cylinder head and timing chain service procedures for these engines.

Many/most will tell you this is normal. I would say it is more expected than truly normal, but it is not a big deal IMHO. Life is good if this is all you are worried about."

 

[QUOTE=Doc Olds;379078]How many miles???? :

Doc=My H3 only has 77k miles and it has been making this noise for years.

 

[QUOTE=ski.dive;379079] The racket usually starts in the mid-late 50K miles if at all. As long as it goes away after startup, no biggy.

 

It might help if you described the noise.

 

Right, or post a video/audio of the sound?
I do enjoy that supercharger sound I get in the morning from my cooling fan before the clutch kicks in.

 

This is how I read this post.
Please help A.S.A.P.!
I have a noise, tell me what it is and how to fix it.
NO, I will not describe the noise.
NO, I will not give the model year,
NO, I will not give you the mileage or any other helpful information other than "first start-up the I-5= there is a noise that comes from the front of engine area, for a for 5-7 seconds, then the noises go away for the rest of the day".
You fawkers have to guess how to help me fix my sheet because I'm special (my mommy told me that).

First it's "a noise", then it's "noises"???
My guess is that it the ding-bat behind the wheel?

 

TAINTER=You really need to get laid with your bitching attitude.

Doc Olds=Already told me exactly what was wrong without complaining.

 

121 posts and you STILL haven't figured out the proper method for asking questions.
YEAR, MILES, Engine, Options/packages if applicable to the question, etc.
If you are truly an officer of the law like your photo suggests I feel sorry for the people of the municipality you are employed in.
