Q: 2.5 n/a D smoke

Hi all

My 85 2.5 naD 90 110,000 miles, most of the time it hardly smokes, allways starts from cold easy I can rev it to the limiter at a standstill and it looks like an mot pass to me (mot tester). Most of the time driving up and down hills and on the flat only a faint trail at nite in car h/lamp beams.

Just as I think all is happy, on the flat accelerating or up hills I get what looks like clouds of white smoke making cars that are behind drop back. It only does it occasionally and only when warm (so far I mostly drive at nite as I'm at work through the day).

I got a m8 to drive it past me twice but it wasn't smoking bad and it just smelt like a normal diesel smell as it passed. I've changed the oil,oil filter,fuel filter and air filter so far Anyone had anything like this?

It's my first diesel I just bought it coz it had a recently new galvanised chassis, and I thought if im gonna have another land rover it mite as well be one that I dont have to lay under forever welding the chassis like the S3 I had :o)

Cheers Jon

If the smoke it really white, that is very white, it could just possibly be you are burning brake fluid - are you losing any? More likey, if the smoke is only whiteish, it is unburned fuel, and could indicate a dodgy injector or pump timing. If you can get it to smoke at a standstill, crack each intector union in turn and see which one(S) make the smoke go away to find the dodgy one.

Is it cold weather at night. It might just be condensation. White smoke is usually water vapour. Is it losing water. Some nights really cold(only does it occasionally),more condensation. Warm nights -no condensation. Yours (same engine) Gmacz

No fluid loss, but can't see how it could burn it.

Its relay weird as it won't do it when it's sat there it only does it on the road no misfire or smoke at a standstill can't feel a misfire when its smoking. I live at the top of a hill and it has smoked all the way up the hill but when i get home and rev it ..no smoke.

Gonna try the timing and get the injectors checked out it could probly do with a t/belt as I don't know when it was last changed. Cheers for the suggestions Jon

(my first diesel, I'm relay starting to dislike diesels)

Don't think it's loosing water, just had to renew the radiator and had a few other leaks that I think are now cured. It seems to be on average after its done 7 ish miles so its nice and hot I dont even get chance to smell it to id it:O( Thanks Jon

Through the servo.....

Your injector would have to be in a *really* bad way to get a misfire, it only takes a slight blockage in the nozzle to mess up the spray pattern and cause smoking.

While your at it, I'd suggest having a compresion test done if you can - particularly no.4 and no.3 cylinders, just to rule out blow-by.

It goes to the vac pump on the side of the engine.

ah, I see

Oh no! rebore and pistons:o(, I was under the perhaps false impression that if it started ok from cold that the compression must be ok. So it can start well from cold and still be bad enough to need a rebore? *

I've just started 10 sec glow (whats the max glow time?), a very short wind over before it fired then blip throttle and it settled down to tickover smoked a bit, now its cleared. Cheers for the help Richard :O) Jon

  • worst nightmare having to recon the engine, did my 2.3 S3 engine that I had years ago dam heavy things.

The 2.5 Diesel will run in just about any condition except siezed!

*IF* that were your problem, then it would be new liners, and that would probably not work for too long - its good old porus blocks again! But don't panic, I'm suggesting you do that at this stage just in case, so you don't spend a lot of time and effort on a duff engine, if you see what I mean. A simple first step for health on the 2.5 D and TD's is to take the rocker cover breather off with the engine running and see if it "chuffs", which would indicate blow-by. The other way is to take the dipstick out with the engine running - if you get drowned then there is a problem as the crank case is presurised.

Dont panic - it's probably fine! But worth checking before the credit card comes out!

This afternoon i gave my 2.5d 45 seconds of glow plugs and it wouldnt start!. So if yours starts on 10secs it cant be too bad!. Mine has been totally rebuilt/reconned, except for the glow plugs (theyre the only original bits left now i think!).

Its getting a set of glow plugs and a new starter motor earth strap this week, I've been putting them off as i cant ever seem to get to the diesel place when its open.

Typically I could have gone thismorning, but was too busy pulling the

101 apart, but then when i tried to leave to go to work the landy wouldnt start! :(

If it's really bad it will blow the rocker breather out on its own! (mine used to do it when i thrashed it up hills or wound it up too far). You get a lovely bulkhead crying oil type effect!

Regarding your smoke, I used to get smoke out of mine when it was warm. I really noticed it when i drove into town and had to sit in lots of queues and slow moving traffic where the engine got good and warm. I didnt notice it when i drove to work along the quiet roads where it was all moderate speed with very few stops.

I replaced my injectors, had my injection pump reconditioned/setup and replaced the fuel lift pump all at the same time. That cleared up most of the smoking! (dont know which did more..) The rest of my smoking i have got rid of by rebuilding the engine with new rings, and its had some new valves and stem seals. Mine doesnt smoke at all now!

Gonna have to borrow a diesel compression tester. Oil does dissapear the sump gasket is leaking and keeping the round crossmember oiled, and some is bound to be burnt. I think there is some blow-by but I haven't tried it with the dipstick out yet. I took it allong the motorway,did about 60 miles at 50 to 65 mph and saw no smoke. Went to work and back (18 miles) to get some tools in the daytime yesterday and saw no smoke.

It's weird as it doesn't smoke all the time it can even go up realy steep hills without a hint of smoke. It started easily yesterday in sub zero temperatures, but when I tried to move it the handbrake was stuck on:o(

I hit the rod coming out of the drum with a wheelbrace and that freed it, but it stuck again if I pulled the handbrake on again. So I spent the evening striping it down and cleaning and greasing it. Its ok now but I found it needs new h/b shoes.

I'm planning on a run to Paddocks in Matlock today to get some bits. A 100 mile round trip from Huddersfield so I can see how it goes in the daytime on its longest trip yet.

It's too cold to be working outside small jobs I can squeeze in at work, but I've allready done the clutch at home. Don't fancy pulling the engine out in the winter:O)

Can 200tdi's be re-linered? as I've been offered one of those that went heavy breathing and has the largest wear ridge I've ever seen (maybe a few mm) probly beyond a rebore. Cheers for the advice Richard :O)

How many miles did your engine have when you had to do that? mines got 110,000 im presuming its still original

You'd be best talking to your local engine re-conditioner type place about that - it certainly can be done, make sure they understand you are talking about a 200Tdi and not a Turbo Diesel!!

I have no idea. Probably more than that - my landy is the engine's 4th home as far as i know.

It's an 84 engine i think, and it was reconditioned when it was taken out of the sherpa, which is probably 10 years ago now.

Did the trip kept an eye behind on the hills (plenty of those) did not see any smoke. Worked out at 30mpg ish over 100 miles. Went over to Millers oils in Brighouse after I got back and half way up the hill leading home started to smoke for about 1/4 of a mile then stopped?? bl**dy weird.
