Hey guys - over the last few weeks I’ve noticed a small ticky type noise on driving coming from someone low in the cabin, thought it to be the cold weather and short journeys so thought nothing of it- just drove to Manchester airport 2 hours straight driving was lovely and smooth , but as I parked up my wife opened the passenger door and all I could hear was a louder tappy / puff puff type noise , so parked up with the engine running and lifted the bonnet and I could smell exhaust fumes - seems to be the passenger side of the engine - bad leaky gasket? I had both engine manifolds done about a year ago and I’m not getting the loss of power restricted performance error so I’m guessing more exhaust based?

Any ideas?

Sounds like an injector copper washer has failed, try lifting some of the sound deadening on the nearside bank and see if you can see any residue or see any blow by with the engine running.

Thanks just seen can be a common problem on the injectors - Cars going into drop n go car park tomorrow for 2 and bit weeks so will give it a check over when I get home. Presume car will be okay to drive home again - about a 2 hour drive.

I'd say so, I drove back from the French Alps, approx 1k without any issue, just a bit of fumes in stationery traffic. Easy enough repair, replace the copper washer and o rings as well as the clamp plate and bolts to be sure of a 100% fix. Not expensive for gen parts.

Thanks man will have a look - car is in airport car park for 2 weeks now so will check it when get back - either that or a loose exhaust clamp? Definitely a puft puft type noise that gets faster with accelerator around the passenger side of the engine - cabin had a strong smell this morning when drove from hotel to airport car park

The crossover pipes are a bit prone to cracking also, but if the sounds the same when the engine is warm I'd say a copper washer, as usually if the crossover is cracked they tend to seal a bit better when warmed up.

Hope it's the injector, it's easier and cheaper!

Yeh it seemed to louden as engine got warmer.
Would anything show on a diagnostics as I’ve got my LR II in the boot so could plug it in when I get back check fuel pressure?

Mine never showed any codes whatsoever, if you just lift the foam insulation on the nearside bank, you'll see fumes and smell it big time when it's running.

Go and enjoy the holiday and worry about it when you get back!!

UPDATE
Arrived back in the UK yesterday dinner time after 36 hours of travelling and I Knew Id have the injector to face I was going to risk it and drive home but after about 2 miles of driving from Manchester airport I had the red triangle and engine fault error on screen I pulled over in Manchester and plugged my code reader in - p0087 Low fuel rail pressure - so I thought it must be linked to the injector seal causing loss of pressure etc.

I called the AA out , Bob arrived in about 15 minutes and diagnosed it as a bad injector - he checked the torque on the injectors and 1 injector was about a quarter turn loose, needed nipping up this stopped the chuff chuff noise from the engine , he then plugged his computer in and cleared the fuel code and asked me to restart the engine - all good no noise no engine fault code

He said just get the injectors checked out as it could be a washer/seal - Car drove back the 120 miles all good I have to say the AAs response and service each time Ive used them has been brilliant.

A definite result and free of charge, what's not to like!!

Update 2!

After some more driving the noise has started to re appear so booked in next monday to get the washers swapped out.

Do people know if they will swap the washers there and then or are the washers a LR part only what they will need to order in?

JLR obviously stock them, but they're a bosch part and are cheap as chips on ebay, albeit only a couple of quid from JLR. I'd insist the clamp plate and bolts are changed too, as the plate can distort and the bolts stretch. For the small extra cost it's worth it for peace of mind.

Hi looking at getting this done myself is it a easy DIY job and can you buy a kit with the bolts?

If one of the injector seals goes (as did mine recently) should I replace all of them (almost 300.000 km in my 2015 L494 diesel - or is it just bad luck, no (little) chance the other seals are going to die also on a short term?
