So my 2005 Corolla Le has been making a bad engine noise when I start it up and let it idle. The noise starts just after the 40 second mark. It’s not constant and only seems to do it for the duration shown in the video. Its a US model and has 142,000 miles.
I’ve noticed that it doesn’t seem to make the noise when I’m above idle.
This is with the A/C off though it will do it if the A/C is on or off.
I’ve tried a couple different oil filters to see if that was the cause (Wix, Wix xp and now an OEM Denso) and it does it with any of them.
I’m pretty worried about it because if it’s something pretty bad I don’t really have the money for a new car so I’d have to try to repair it or something. It’s been doing this for several months now. I would really appreciate any thoughts, advice or ideas on this.
Update: Found it! There is a heat shield on the exhaust manifold that is missing two screws and is vibrating when the engine is idling! Thanks Traitor Joe for the suggestion! I’ll figure out what bolts to buy and install them at a later time. I’m glad I found it and can stop worrying so much about it! Thanks everyone for the suggestions and advice!

Hmm. Early 1ZZ-FE’s are notorious for sludge problems. I hope it’s not that...

sounds like an exhaust shield rattle or something to me. That would also explain why it only happens at low rpm, since it would be vibration dependent. I wouldn’t worry about it too much but you could go around your engine and look for things that might be loose and rubbing on something

When I had the valve cover off last year it looked like this so I’m doubting sludge. Granted that was a year ago but I use full synthetic and change it every 5000-6000 miles.

Okay I can definitely do that, there a good amount of room in the engine bay so it should be pretty easy to access the heat shields.

Interesting. I run conventional every 3,500 miles in our not-a-Corolla. Speaking of which, I’m a few hundred miles overdue!

Yep, got 104k miles on our ‘08.

I agree with the above. Sounds like possibly the heat shield.

I found it! There is a heat shield around the exhaust manifold that is missing 2 screws and is vibrating and I can stop the noise by grabbing it. Thanks for the suggestion! I’m glad I can stop worrying about it!

It was! I found a heat shield around the exhaust manifold that is missing two bolts and appears to be making the sound. Now I just have to figure out what size bolts they are and install them. I’m glad I can stop worrying about it.

One less thing to worry about is always nice!
