V8 Vantage noises

[lestrat]

Dear all,

I would like to share with you some noises I find quite weird in my car. Most people here is familiar with these cars and probably some of you know where do they come from, and whether I have to worry or not.

After driving the car hard on a mountain road, I heard the noise that <hopefully> you'll be able to hear in seecond 17 of the following (crappy and with low volume) video. It sounds similar to the whistle of a turbo wastegate. Is that the oil pressure relief valve?

The second noise, in the following video, I assume it's the timing chain, and I noticed in several videos of other V8 Vantages that it is a normal sound for this engine. But what concerns me is that the noise is much louder after driving hard, is that normal?

And last but not least, when the car is cold, during the first 5 minutes, theres another noise, which I think could be the oil pump, but I checked the oil level and everything is ok, is that normal, too? I hope I will be able to make a further video for that.

Thank you for your help.

Sorry chap, for my hearing at least, from those clips it’s pretty impossible to decipher anything.

Thank you for your response Mike.

Is it because the sound quality (I know it's pretty crappy, because it's recorded with a cheap chinese action camera), the volume of the videos, or just that you don't find anything unusual there?

In the first video, I would say that the sound is pretty noticeable, at least with headphones. There is whistle noise in second 17, quite similar to a turbo wastegate. I made a mistake in my first post stating that it was in second 10.

In the second video, the noise is actually the only thing that can be heard. I was driving with pretty high revs and coasting, so that the "timing chain noise" was the only sound produced. I would say that that's the normal engine sound, and it has a pretty loud timing chain.

It's difficult to hear the first sound clearly but I've noticed at altitude my car has a noise as you describe. I've noticed it a number of times going over higher passes and it goes as soon as I descend. I've not noticed any drop in performance and temps seem fine so hasn't really worried me.

For the second sound I don't hear anything wrong, sounds like a Vantage! I do think the Aston V8 is a harsher sounding V8 when reaching the upper end of the rev range, certainly more so than the V8 in the E92 M3 for example. If you do have concerns about odd engine sounds I'd take the car in for a check up.

If this whistling noise is somehow related with pressures, it makes sense that it's done more noticeably when it's very high. That's on top of Flüelapass, so almost 2400m

Does anybody have a recording of the sound made by the oil pressure relief valve?

As others have said: you can't hear a thing in the videos

But my 2008 Vantage sometimes also makes a whistling sound when accelerating.

When going past 4000 rpm, it's like there is an owl in the engine compartment

Whooooohoooooo

Have the car now for 3 years, and it has been doing it since day one.

For the sake of my sanity I’ve decided to adopt the position that all of the sounds mine makes are perfectly normal. If any of them stop, I’ll start worrying.
