So there is a rattling sound coming from the front passenger side part of the engine. I took it to one mechanic that says it might be the timing chain guides but another two mechanics say they don't believe it's the timing chain but they can't figure out what it is. One of them said my tensioner was vibrating and bought a new one and replaced it. It calmed down slightly but I still hear the noise. There are even times when the engine seems to shake quite a bit. I do have other issues in the car that I need to take care of such as motor mounts going bad 6 months after replacing all of them. I need to replace my front suspension again after 2 years, mounts and suspension have lifetime warranty so just have to pay for labor to get new ones installed. My transmission seems to work great but it seems to shift roughly into reverse and drive. But the gearing and everything else shifts great. No loss of power, no check engine lights. Just getting really frustrated and I don't want to spend $1,300 on a timing chain if that is not even the issue. Mechanics checked and there are no metal shavings in my oil and the check engine light isn't on.

Any help would be great. I live in Arizona if that matters.

 

Could be engine mounts, rattling exhaust, coil packs or spark plugs. Pretty much a lot of things. It should be tested when some one under the car while engine is idling.
Don't cheap on parts this car NEEDS OEM parts (especially electric parts) or you'll keep paying for labor every now and then.
I run for a mile from a part that has "lifetime" warranty it means they are made cheaply and buyers keep changing them and maker just recycle trash between users.

 

Could be a number of things.. Check the mounting bolts in the a/c compressor.

 

There is a heat shield that is rather famous (infamous?) for ratling that can sound as if it is coming from the right side.
