V8 Vantage - Oil scavenger pump noise when cold..?

[jus]

Do you lot also get a short low-frequency whining noise from the engine bay when starting up or loading the drivetrain when cold?

Hard to describe but if you get it you'll know what I mean. Everytime you start her up from cold in the morning you'll hear it sort of spool up and then go away... might come back briefly when you load the drivetrain as you engage the clutch on pull away or something similar.

I've been told this is the dry sump oil scavenger pump and that 'they all do that'.

It's your oil pressure relief valve. This can be removed and replaced with an upgraded valve. By having this done under warranty, you'll also have the front engine cover resealed. These 2 problems are very common on V8 Vantage.

I've had the upgrade done and it does cure the problem

My 07 roadster has this same problem and they suggested changing the valve for a new upgraded one, as suggested above, to resolve this issue.

Thanks guys, will take this up with the dealer.

Ditto....Mine's at the Works Service having this done as I type.

I've just noticed this in the last couple of weeks. Only happens for a few seconds when I've done 4-5 miles and changing down, so under light engine braking, but once warm there's no sign of it. Mentioned it to the garage and will keep monitoring it. They said there was a fix to replace the oil valve but suggested it would only be necessary if the problem became more persistent.

I have had this noise since new. Was told it was just an engine phonic and not to worry all V8s do it by HWM service. No mention of a warranty fix. I think a word is in order.

Just a little more info, I was told that to change the valve the engine timing chain has to come off, along with other front parts of the engine which is a semi-major job.

The dealer did explain to me that it was not a problem for the valve to make this noise and in no way does it affect performance or reliability. Thus I have decided I would live with the noise as opposed to the dealer techs removing the front of my engine which *may* then lead to other issues if not done properly.

However, if I were to keep the car for a lenghty period of time then I would have had it changed.

Haha... it does sound like the voice of a wookie! Good description for it... anyhow, I'm not too fond of the noise as it's gotten a bit louder recently, and it's not really all that suave is it now!

Had relief valve changed under warranty month or so ago, and it stopped the noise which was there and reported from new at May 2006
