Car Rattling Sound - Cold Engine - In Park (Saturn Vue 2007 3.5L V6 AWD)

[seansaturn]

I'm not sure if it's the cold weather or whether this is an issue getting worse.

Video here: https://youtu.be/3jSH5bjL27U

1. This only happens when the engine is cold. After 2-3 miles, I cannot hear it, even when in park. If car is warm and I turn it off/on, no noise.
2. When I put the car in reverse or drive, the sound seems to change pitch or disappear.
3. When I rev the engine in park, the volume increases

Sounds is like a rattling/clicking sounds. It's hard to put a specific word on it, but I hope the video helps.

Ignore abs light (fixed now) and oil light (Oil light comes on for the first 15 seconds, oil is new and fine).

Go underneath and check the metal heat shields around the exhaust system.

Thanks for the response.

I'll take the wheel off and take a better look. I couldnt see the catcon heat shield very well

Will update soon!

...Almost sounds like engine knocking , until warmed up.

I am leaning towards motor mounts, I have a similar issue and after researching related threads I have new mounts to install, just need some time.
I will post the results, just don't know when.

Before the knocking noise got bad I had noticed a vibration at around 40mph for quite a while. I always thought it was the transmission because I had read about torque converter issues and so on. So around 100,000 miles I changed the trans fluid for the first time (mistake) and every 10,000 after that. The vibration seemed to get better, but it never really went away after I started maintaining the trans fluid on a regular basis. When I changed my motor mounts the vibration I had always noticed went completely away! The car seems like new.

So if after trying all this other stuff and you still have an issue, try changing your mounts.


Take care

I also have this 40-50 mph growl at low rpm.

Thanks for the feedback.

I am planning on changing the timing belt and water pump in a few days. I need to remove an engine mount to access the area for this job.

Are there any things to look for visibly in a bad mount? I have noticed the car shudders when shifting into reverse. They are $100 a pop on rock auto (but $8.25 at the junker), so i wanted a good way to check them for both reasons!

I have been picking them up on Amazon "used", which they are not, for half price or better when they have become available. I have 3 of 4, just waiting to get the left side trans mount. I may not need all but this way it will be done complete. This place has the best price on the front (radiator) mount
https://sdparts.com/i-24089224-acdel...-15801384.html ,which is oil filled and I think where the problem may be as per my thinking the oil warms up, increasing pressure, and the noise goes away.
The other mounts you can pretty much see if they are torn or worn out. The S series were notorious for worn mounts.

Guy selling 04 on CL says his vue has been making noises for several yrs. says it seems to get louder when you drive. Maybe it needs mounts? He wants 700 for it.
I paid 400 for a similar one last yr that had bad starter. Sold it in 2 days for 1700
