discovery td5 engine noise...?

[jaydebob]

Hi all i have a 2000 reg td5 with 97000 miles on clock , which runs well but when under load , ie flooring it , overtaking ect. can hear a shhhhhhhhh noise sounding like its from the engine , ive changed the turbo , and fan , and had new belts all round ....not sure where else to look , has anyone else had a kind of noise like this , what the heck is it its driving me nuts...please help cheers

Just a thought!, flexible joint on downpipe, is there any sign of blackening around the outer braid, suggesting a leak? Turbo pipe leaking?

Hi could possibly be exhaust manifold studs they are bad for snapping and they cause quite a loud blowing noise.Lawson

hi again checked those , seem fine ...?????? seems to quieten when you press the clucth while travelling but perhaps would do because its no longer under load,.thanks for your thougts though .....

Not wanting to scare you but I think my td5 made a noise like that before the oil pump sprocket fell off, due to the bolt working loose due to Land Rover's inconsistent policy on application of Loctite 242. If you get an oil pressure warning light- stop the engine ASAP, aand get it towed away.
It's not too difficult to drop the sump and check the bolt for tightness; better still, remove it and apply Loctite: I wish someone on the Disco II forum had warned me.
Hey, if I'm wrong, sorry, but I did remember an odd noise. Better safe than sorry.
'99 Disco II EU2 type td5. It happened a month ago.

hi there thanks for the advice ill definetly have a look at that , is it actually in the sump then,does it have a torque setting or is it just loctite and f*****g tight.

[jaydebob]

also has anyone heard of the rotor filter making funny noises......could it be that..

[soupdragon]

not that f***ing tight; in fact the torque wrench I borrowed didn't go low enough: it's 25Nm metric or 18lbf.ft in inchric. The Loctite should do the job, anyway. As I said, I may be wrong, but having just suffered it and had to pay 500€ for a new oil pump/stiffener plate assembly, I would rather have done the sump-off job, even if it hadn't been necessary. Oil pump is on the port side, forward, easily visible once sump has been dropped a bit. I've seen forums on the web where people a few years ago were saying there weren't likely to be any more cases of this stock fault. Wrong!!

lol im doin it tommorow , gonna change oil while im at it ......thanks for your help..

Yep, they do sometimes sound a bit like a turbo winding up. Could the noise be from your tyres?, I have a 'whine' from the tyres on very smooth road surfaces(rib type tread road pattern).

hi donny thanks for your reply , i think it could be the rotor, sounds like it , wont hurt to change it anyway , dont think its the tyres as noise seems to have been gettin worse gradually.......cheers

hi there it there a lack of power if so i think it could be the turbo intercooler leacking air

[willie007]

hi sorry this is the first time i have used this forum but as far as your engine noise gos i think it sounds like the turbo intercooler is leaking air

[jobo]

did you really change the turbo, just coz it made a funny noise ?

how much money have you got

[jaydebob]

hi willie007 would you be able to see where its comin from do you think or is it a matter of just changin it.... hi jobo yeah bought a brand spankin new one to try and get rid of this annoying noise only to find it didnt get rid of it , what a pig...........

[TEMPL4R]

As Willie says, intercoolers split and make a noise. We've changed quite a few on L322s, BMWs and Renaults.

Look for traces of oil and bowed coolers. Split pipes and bad connections are worth looking at as well.

Been out in the disco today towing a trailer , sounds more like a scraping hiss if you know what i mean coming from either the gbox or engine but only under load ,more or less the same time as when the turbo kicks in , checked intercooler and pipes all seem good ,

how much do you want for the old one

[willie007]

hi you might not be able to see were the air is coming from but if you remove the intercooler you can test it if you have the gear to do so or you can get it tested easily

sorry ebayed it......
