2.4 Tdci on its last leg ?

[furianer]

Good evening, long time since I visited this forum, guess to busy fixing Landys of all sorts.
One of my customers got me this nutcase to sort out for a x-mas present

Anyone with the same engine noise out there

Defender 2007, stock standard, 214 000km
Oil pressure ok, crank case pressure ok, slightly more pressure in coolant system than others
Serviced regularly

Can't wait to hear what others think

Sounds like either bottom end bearing rattle or a crook injector?

[Toxic_Avenger]

2 problems I can see:
Steering wheel is on the wrong side.
No defender wave as you drove past.

Other than that it does sound crook

I had a similar noise on an old troopy , it has spun a little end. Oil pressure was fine and apart the noise it ran fine so it is a possibility. Check the injectors though as a faulty injector can make a horrible din.

Thanks Chris

Did cross ny mind also, but I'm not convinced

Here is another one

It cant be bottom end or you would have lost oil pressure by now and it would be a heavier knock. I would be checking injectors first, I have not worked on a Puma yet but MANY other diesels. If possible disconnect one injector at a time see it the noise goes away. If injectors are fine I would be doing a compression test just to eliminate cracked pistons or dropped valves. If all good ie not injector and compression good it has to be a little end or something deeper in, cant think what else it could be though..

It's a bit hard to tell by listening to the video. Is it definitely a mechanical knock? Could it be as simple as a loose exhaust manifold both choofing and rattling?

[PAT303]

I doesn't sound like bearing knock to me but it's hard to tell,sounds more like an exhaust problem but hard to know. Pat

[nismine01]

So, is the noise there at idle?

If not, can you duplicate the noise whilst stationary?

An old piece of garden hose, (stethoscope) in an ear the other end against the cylinder head then down to the engine block may assist in location if you can duplicate the noise whilst stationary.

Figure the injector noise would show up more at the top end than a dudgeon (small end).

It may help:confused:

:D. LHD Defenders feel a bit wrong

Defender wave, the Ninety I drove past is another half dead one, but that is another story

Chris, thanks,

See if I get a chance to do some tests today

Thanks HUE166

Definitely a internal engine noise, some of the rattling heard is the gear stick

[manofaus]

Easy way to check injectors is to drive the car and just turn ignition off. Or get it high in the rev range and back off. Either way your injectors wont be working. I third a manifold leak.

[furianer]

had a bit of a look see this evening,

injectors leak off test, runs with the comp hooked up

injectors out

endoskop showed lovley looking pistons. bores. spray pattern and valves, expected a lot worse with this milage

Valve cover off

this could be the answer or at least one of them

this little clip shows exhaust valve Nr. 3
cam lob and follower. hard facing worn off, follower out of round


nice evening to all of you, thanks for all your inputs

Thats more common on all types of motors than you think,cam repairs weld them up and regrind them. Pat

[furianer]

thanks Pat not wrong,

i reckon it is all down to servicing and using the right grades of lube

the owner of a engine and gearbox reckon workshop i know once said

if vehicle owner would half the miles between services and use the correct grade and quality of oil
transfer case included

it would but him out of buisiness

wish you all a plesant x-mas break
