Can anyone identify this tapping noise?

Hi All,

Just wondering if anyone can identify this new tapping noise that has appeared on my 2007 RRS 2.7 TDV6?
Doesn't sound real good to me!

Thanks

It doesn't sound good! But I can't diagnose that from the video, maybe someone else can....but I would not be starting it again until it's been checked by a workshop that knows that particular model motor.

Could be numerous things but mine sounded like that when one of the injectors wasn't seated/sealed correctly after replacing the copper washers.

A few worrying videos to compare the noise with.

Discovery 3 2.7 TDV6 engine noise - whats the problem here? (Spoiler - it was a spun main bearing) - YouTube
Range rover sport 3.0l Tdv6 Engine Tapping Noise.. Any one got any ideas..? - YouTube
Range Rover Sport - 2.7 TDV6 Top End Engine tapping/hammering sound - YouTube

The last video was never resolved what it was.

I wish I hadn't listened to those! The OP sounds like the top end to me.

Thanks Shack,

I live up in Gladstone QLD so they are hard to find!!

Thanks again Disco DB, Sounds more like the last one that was unresolved to me.

Cheers loanrangie,

I'll check the injectors.

I've put the same on the Range Rover forum, just to add Disco DB and my response-

Although sadly the cost to rectify either case will be the same, but at least one outcome is rebuildable.

I personally would pull out the oil filter, cut it open (so I could expand it fully) and look for metals bits between the accordion. You can also get an oil sample analysed to confirm it is (or isn’t) a bearing failure.

When you remove the oil filter, look to see if it had a crushed spigot due to not being fitted properly.

That is planning for the worse. Hopefully though it is something a lot simpler and cheaper to fix, and someone will pipe in with a much more optimistic theory.



Thanks DiscoDB,

I have removed the Oil filter and it looks all good, no crushed spigot. I have drained the oil (looks good) and removed the oil sump to check. I found about 6 small flakes that looked a copper colour? but no other metal shavings etc. I'll do the filter chop tomorrow.

I haven't had it for long and the previous owner replaced the engine due to the old oil pump housing failure with a low klm engine
that had 50,000 k's on it, now its about 69,000 k's. Would be very unlucky to replace it again!! I've always looked after it and replaced the oil twice in the year I've had it. Fingers crossed.

I'll suss out getting the oil sampled.

Cheers mate much appreciated.

Would anyone know a good LR mechanic in QLD that could help me with this?
I don't mind putting it on a trailer and going the distance!

Cheers
