2011 SV6 sounding like a rattle gun.

[james10]

Hi It only lasts a few seconds and happens about once a week. Seems to be at low speed under gentle acceleration. A couple of times coming out of a roundabout.
It is quite loud. There was a youtube vid on this site a long time ago that sounds quite a bit like my car is making.

Hoping some gurus here may be able to help. Car has always been serviced at local dealer and they do not have any ideas about what the problem could be. The link is not working here but if you youtube VE holden commodore omega crunching grinding noise it will pop up. Thanks

Apparently the fix is to replace the oil pump pick up seal in the sump.

Read the comments below the video.
You need to watch the video on Youtube to see the comments.

That video of your car sounds to me sounds like the timing chain is on the way out

Do you need to take the engine out to drop the sump to check the pickup ?

And this is a VZ SV6, 2011?
I would expect Holden to know a bit more than perjure that they don't know what the problem is!

Get the engine serial number (passenger side, down near the transmission hump join). Photograph it and look it up in the range of engines affected by timing chain elongation. There is a lengthy thread on this subject here on the forums somewhere that gives a list of the affected engine ranges. That is what this ratcheting noise sounds like, the timing chains; as the engine warms up to normal operating temperature, the racket calms down, but deep down inside, a perfect storm could be brewing.

This fault also affected the early 2009 VE Commodore (which came after the VZ), OMEGA, Commodore International and a couple of others -- any and all running the V6 Alloytec and the first generation SIDI V6.

Thanks big red

Did the seal replacement fix the problem? I have one that sounds EXACTLY the same but the noise is there all the time. Thanks
