Strange engine noise

[danm14]

I have a strange ticking/rattling sound coming from my sdv6 d4.
Seems louder while idling and does it cold and warmed up.
Doesnt get louder when driving and I cant here the sound from inside the cabin.
I have no loss of power or any ecu codes showing up.
Seems louder from the passenger side of the engine.
I will post some links to youtube where I habe a couple of videos.

Have a look at the serpentine belt. In there you’ll see an idler up the top on the belt run. See if that’s moving about a lot. It sounds like it could be a faulty idler allowing the belt to flap. It’s not uncommon. How long has it been doing it? I’m hoping it’s that simple.

I just noticed it the other day...
Hopefully it is that simple!!!

Land Rover TDV6 3.0L Drive belt tensioner failure & repair - YouTube (https://www.youtube.com/watch?v=57hL-edUU8g)

Agree with the general comments so far, remove the engine cover and have a look at the serpertine belt tensioner (bottom drivers side down near the alternator) as it may have failed. Its the actual tensioner that fails and not so much the idler itself - the tensioner falls apart and the belt dosent run on the pulleys correctly - especially the alternator pulley.

Thanks for the reply guys.
I had another look, and I dont belive its coming from the pulley or belt area.
Still sounds like the right side of the motor.
Also noticed an oil leak around there and the filter housing.
I recorded another video with the cover off and emphasizing the side which the sound is coming from.

I'd seek professional advice. It's very hard to pinpoint on a video recording. There is an element of sounding like an open exhaust sound to it as well. I have heard of the rear exhaust pipe that joins the left and right sides together failing. It's buried behind near the firewall. Other than that, sorry, dunno. Keep looking, feeling for leaks etc, if it's not the belt.

This may or may not help but I remember my old man using a length of dowel held against the engine to locate noises. He would put his thumb over the end and press his ear to the thumb. Apparently the sound would travel up the dowel and he could hear if something was wrong. May help you locate the location better.

Any luck finding the source as yet?

I used long screw driver for the same reason, then I came across a stethoscope which is much better

We were really poor and couldn't afford stethoscopes much less store them in our home in the scrape in the road in which we lived. (Apologies to Monty Python etc)[smilebigeye]

Luxury!!

I have a similar sound from mine but only when warm. Any luck finding the source?

You lived in scrape in road? Luxury, We lived in...

[DiscoMick]

We didn't live anywhere really, we just huddled under umbrella.

I had the same noise. Just had the belt tensioner replaced along with a new belt. Noise now gone!

Was your's intermittent Scomac?
Mine seems to be there only once it's warmed up. I'm leaning more toward lifters than the pulley...

Hi Martin

Not intermittent, you could here it straight away from start up. I think if yours was a bearing you would be able to pin point it.

There are some youtube vids of d3/4 tappet noise I came across which might help. They're hydraulic as you probably know, so if they're noisy (like every Mitsubishi ever made), if an oil change doesn't help, they will have to be tolerated, or replaced at great expense.

Liquid Moli do a additive for hydraulic tappets - available from any of the auto stores (on special at Super cheap until 11/2/18)
