sick defender

[mills rover]

hi guys and gals

My 200tdi defender is blowing heaps of smoke and running what seems on 3 cylinders when i first start her in the morning then when temp is normal she runs normal all day long you can start her another 10 times threw the day and shes as good as gold
ive tryed changing cranckcase ventilator as ive found oil in my air cleaner and after putting new one on and new oil cleaner i thing she,s worse definetly getting worse .
i thoguht it could be a cracked ring or maybe a ring thats stuck but why does it come good once it gets up to normal running temp i also though because she runs so rough when i first start her it could be an injector thats leaking threw the night but that doesnt explain blue smoke that hangs around for ages before it disappearsand definetly smells like oil burning
im lost any help would be appreciated thank you
by the way shesdone 250thousand k,s been well looked aftered never goes more then 5 thousand without an oil change make sure of that.
anyway guys and girls have a great weekend whats left of it and keep loveing your landy ;)

hi guys and gals
can anyone help me with this problem with my sick defender any help would be appreciated thank you

gday it could be something to do with the fuel system if u can get some bio diesel change your fuel filter and run a tank of it as it will clean out your tank ,lines ,pump and injectors

[mills rover]

i will try it mate i was going to replace my injectors next but ill try you theory first mate
thanx again

If you run bio diesel through it, make sure you change your fuel filter and clean out the sedimenter (if your 200tdi has one - mine was never fitted with a sedimenter) OFTEN.
As 'defmec' said, the bio will clean everything out and as a result, will clog your filter more quickly than normal. Carry a spare filter while you are driving around also, just in case!

how are your turbo oil seals, if they have had it they leak oil this can give you smokey exhaust as you are getting oil going into your inlet manifold. 250000k on the clock have you ever had the injectors done,if not you probably should it can't hurt. :D, let us know it what it ends up being

[lambrover]

running rough when cold, you mentioned rings, when cold and worn they don't give a good seal against the bore thus you have less compression this gives poor running but when it is at operation temp they have expanded and form a better seal against the bore. dose it stop blowing smoke when it's at operating temp.

thanx guys
ill try thr biodiesel but does anyone know where to get it from in melb i dont think ive ever seen it as far as turbo goes had it redone about 5othousand ks ago had a new mitsubishy one put in injectors ive never changed so i ordered a new set thew les richmond tonight and yes as soon as it gets to running temp it stops blowing smoke but if i stop for a few hours and she cools down bang smokes again its got me buggered but i drained the oil tonight which i only changed on sunday and it was dirty as hell and smelled of diesel so good chance its the injectors bleeding in as it sits over night also today it started but ran like a petrol engine thats flooded .
ill try the biodiesel though and replace the injectors and then see maybe i might have to pull her down and rebuild her ..
thanx again

[lambrover]

if the injectors are leaking the cause most likely is the needle not seating or worn out and I don't reaken running bio will fix that problem, maybe look at getting a compression test befor you pull the engine down.

[mills rover]

lambrover im going to replace injectors try bio diesel change filters again and put new oil in her then if all fails ill give her a comp test and think about forking out for a rebuild mate which i dont think will be cheap till last week she started first touch of the key so i dont think she should be in that bad condition touch wood ive had other diesel where they were so worn that they struggled to start . what i can i say one can hope that something goes well mate .thank you again

[mills rover]

lambrover another thing i forgot to mention is till this problem started last week i could change the oil in her and it wouldnt show signs of dirt for a few weeks the oil actually stayed clean for quite a while this time ive changed the ouil on sunday hardly drove the her but monday the oil was already dirty that was weird mate

[Blknight.aus]

old injectors not patterning properly till theyve heated up...

Fozzy does it but I also think Im having valve stem issues or Ive got a couple of sticking rings.

its also not helped by lowered compression due to wear.

[mills rover]

thanx blknight im going to try injectors first mate ive already ordered them and then see what else it could be from there i worked for 2 years in brissy wish i knew you then we could have caught up and gone and done some 4wdriving mate i was living in eight mile plain not that far from ipswich any how im up that way early next year will let you know and catch up with you for a beer mate my son lives in rocky so i drive past your way on my way there .thanx again mate and hopefully ill work this out without having to rebuild her and if i have to well that be i love the old girl too much . im looking for a series 3 tray might look arounf qld as when i was uop there i saw a few and when i lived in townville and cairns there were a lot of them around definetly more then i saw in melbourne once i moved down here mate..

If it is difficult to start cold, and the smoke stinks like unburnt diesel, then my first port of call is fuel timing.
Forget glow plugs, a Tdi will start without them.
When did it last have a timing belt? What were the valve clearances set to?
It is also possible that the front crank pulley bolt is loose, and causing the keyway on the crank gear to flog out causing mistiming.
Check these things immediately, as the longer you leave it the more it will cost to fix. (can be as bad as a new crankshaft for example:o)

thanx jc timing belt was done ten thousand ks ago as far as valve clearences ive got no idea i havent checked them and front crank pulley i havent checked but best i do that now that you,ve mentioned it . with that keyway been out and timing been out because of it wouldnt it run bad when shes hot as well as when she,s cold obviously im no mechanic so thats why i ask you guys thanx again jc

Not necessarily so. A few degrees retarded will cause difficulty starting from cold, but will start readily hot and still have reasonable power. I'll put it this way, IF it is the problem and it gets rectified, you'd notice a power increase when hot running. Like worn shocks, you don't realise how bad they are until you fit the ne ones...:o

Checking the pump timing is easy, your's dosen't have A/C right?

Remove the cover plate at the front of the injector pump on the front cover. (3 bolts, tin plate)
rotate engine until the 'u' shaped slot in the front of the pump gear is about at 10:30 O'clock.
You should be able to fit a 3/8"(NOT 10mm) bolt or drill bit shank into the pump through this aperture. If not, gently rotate the engine back and forth until the tool can be slid in about 50 to 60mm,.
Next, climb underneath the vehicle and remove the wading plug from the bottom of the bellhousing(If it is fitted) and look up to see (hopefully) a slot machined in the flywheel, central to the hole you are looking through. If the slot lines up and the timing pin is in the pump, the timing is fine.
If the slot isn't visible, there is a serious timing issue. If one side is visible, the problem is definately timing. This equates to about 2 or 3 degrees, and it is enough to cause poor starting from cold and smoke.

To adjust: visually centralise the slot in the hole, or use a timing pin tool to lock the crankshaft. loosen gently the 3 bolts holding the gear to the front of the injector pump through the front cover plate. While doing this, make sure you hold the main nut on the end of the injector pump steady with a 7/8" ring spanner. Keep hold of this nut while the 3 bolts are loosened, and rotate it slowly until the timing pin,(3/8" bolt) slips into the front of the pump body through the gear. When this has occurred, tighten the 3 bolts on the front of the pump, and remove the 3/8" bolt. rotate the engine 2 full turns and check that the slot in the bellhousing hole is central while the timing pin can be inserted. remember to make certain the pin and the locking tool(if used) are OUT and in your hand when you touch the ignition key:eek:


I expect a full report tomorrow.
