Strange howling when I start up.

Strange howling when I initially start the car. Then it goes away. Any ideas? Lasts about 5-10 seconds. Not a whistle. Don't think it's the valve cover. Although it looks like po replaced it. Looks like cheaper aftermarket

Hard to say unless you record the sound. Is it a v8? Or inline 6.

6. 35i. N55

If you look deeper, maybe , …….

But other than that, it sounds fine.

Lmao. Thanks. But I didn't happen to see that in there. I have 2 other n55 cars. They don't make this sound. Hard to hear in a video clip.
