We are trying to identify the cause of this engine noise on a 2011 TDV8 4.4.

It's only done 92K miles but does seem to have been overfilled with oil by a previous owner (we bought it knowing there was some kind of engine noise). Before we started it we removed over five litres of oil using a vacuum pump and the dash still said it only needed one litre to top it up to the correct level.

It does sound a little out of sorts on the front left cylinder as you stand in front of the bonnet but we can't quite work out if the noise is from a problematic rocker, valve or something peculiar such as a broken am chain guide, etc.

All thoughts and suggestions welcome before I have to remove the head for a closer look.

I think that area has the vacuum pump. Could be faulty? Non of your you tube videos work for me.

What error do you get from YouTube?

Blank screen with 'private video'.

Even now? Damn!

Works for me

Works for me now. That sounds painfully expensive!!

It doesn’t sound good to be honest. I think I would take the belts off along with anything else that turns externally including the vacuum pump. If it’s still there then it’s a case of stripping the engine. There is a warning in the manual to not drive it if it’s over filled. I guess there must be good reason for that. Hope you get it sorted.

I have also heard that the oil level sensor can go wrong giving a false display. Best to drain all oil and refill, you could have taken oil out for nothing if the sensor is up ?

Anyone heard this noise before?
