Still waiting for some strip-down pics to add to my collection....  

Here's one to keep you going....

None taken, but plan is to lift old engine on hoist, and take some from all angles....   ....but need to wait until someone strong enough to help move to where I can get hoist on it...

So a massive thankyou to Omegatoy, Kevin Wood, LFF64, Bo Bo, and Tunnie, for your time, your effort, your skills, and your commradeship today.  Personally, despite the fact the rather car is possessed by some evil spirit, I had a very enjoyable day.  Bloody knackered now though.

Thank you

I agree, despite being cold & wet I enjoyed the whole day (well apart from the drive home, boy was I cold  ).

Was great to meet LFF64 & Omegatoy (that's one fast tractor  ) & I learnt a few things  

Sometimes it helps with understanding to see a car stripped like that.  Makes things easier in the future I reckon.  For instance, no way would I have attempted removal of, for example, PAS pump.  Having seen it now, it is so easy.  I'm glad you got some new knowledge from it, although I know we spent most of the afternoon/evening getting the box on

well apparently the procedure is:

Remove

Remove engine cover.
Loosen closure plug on fuel filter approx. two turns.
Actuate starter until fuel escapes free of bubbles at closure plug. Seal closure plug. Collect escaping fuel.

Inspect

Whilst the starter is actuated, loosen all injection lines in sequence at the injection nozzle holder with Line Wrench KM-812, until fuel escapes at the injection lines.
Seal injection lines again – tightening torque 25 Nm / 18.5 lbf. ft.
Collect escaping fuel.
Install engine cover.
... can be found in a certain program (ahem  )

Thanks, will try later

TBH, as it was getting really wet, and the light was going, and my back was killing me, and the backs of my legs were finding muscles not used since I was little, I was more than willing to stop and have another look today.  Its all back together (seemingly correctly!), which was my target for yesterday, so I was pleased with that

Jamie tell me to shut up if you like but. Are you 100% sure theres no air in the system, was it bled from the pump first then the injectors also is the fuel stop valve stuck half way..I am not familier with the BMW td fuel pump but i was a diesel fitter for 11 years and have had the same problems, especially with lots of smoke being pumped out i think i read earlier..

No, I haven't.

Under impression, these were self bleeding - I was expecting air in, but before on old engine, this was cleared fairly quickly.  No obvious bleed near pump or injectors?

I take it is a rotory pump if so slacken off 2 injector pipes on pump just to get air out of pump then 2 on injectors while turning over. you might get air out of it with hand pump if fitted..Always works for me on diesel engines..Does it have a fuel solenoid if so make sure power is going there or give it a light thump with spanner.. Of course as i said im not used to these engines and things have come a long way since i played with things. ECU controlled nightmares..

Not sure what bleeding method is needed, hopefully someone will be able to tell me soon

Jaime. I am sending you a full set of new glow plugs with laidback. A little something for that knackered gearbox - feel i owe you one.

Also, I am digging out my pics of the vacuum pipes. From memory you just have the big servo pie down the middle of the block then one spur off to the right and the one to the front of the engine. I will find the pics.

Ronnie, I have the plugs from old engine, which I will change over if others think thats the problem.  Really just looking for ideas on the poor running at the moment.

Sorry to hear you are still having problems, it sounds as if you are nearly there. As far as testing the glowplugs, from what you say its a pain to get to them to check them. Is it not possible to check them from elsewhere, where the drive signal is derived from ?. Where do the glowplugs get their volts from?, is it a common line?.  A bit long winded, but if you could get access to the wires that feed them, you could use a clipon ammeter to check if each is drawing current, which might save a lot of dismantling. best of luck.

Easier to get to plugs than the loom that sits just below the plugs!  Bloody BMW.

rather BMW.  I hate them. I really hate them. Why oh why oh why do you change the size of the pulleys you stupid people  .

Right, swapped the crank pulleys over, got belts on, all the inlet, turbo all connected, airbox on, rad and condensor all in, along with leccy fans, a/c all connected up, fuel pipes in, vac pipes possibly wrong.  Tunnie came round, so I let him do the gearbox loom and attach exhaust to turbo.

Ign on, then a quick Tech2.  Only engine code was an old 96 that I was getting (most likely due to the vac all being rubbish), so cleared that out.  So, ye of little faith, Omegatoy, the connectors must all be 'TheBoy proof' (except the one from the injector back to loom had a different connector - typical rather BMW, changing it for the hell of it  )


So, with everything done, it was time to start.

It starts (just), and runs (poorly), so that is a start.  It is most definately a misfire short of a full engine.  It needs throttle to help it start, it will idle (very lumpy) and won't rev beyonds 1500rpm.  It is noisy, and boy does it smoke - they is a huge soot mark on the drive behind it.

I think it is so close, just needs an expert to help me with the final step.

The final step - changing the burnt out valves in the new lump?  [smiley=evil.gif]

In all seriousness, if there's anything I can lend a hand with....

Any new codes since it's been run?

If not, I suspect the fault to be fuel related... managed to bleed it?

I've got a gut feeling about glow plugs...

Im impressed you've got so far with it TB  

Tho dont think it will be glowplugs causing the prob.....my old merc diesel used to start on the button in this weather......used to struggle a tad in winter....and that had 3 duff glowplugs....

Plus woulda thought tech2 would tell you about duff glowplugs.......if theres not a warning light on the dash like on old merc....telling you duff glowplug/s

Not sure BMW designers have the necessary intelliigence to be able to design something that warns drivers of such failures.

Well there easy to check anyway.......pull the plugs off em.....and shove a meter on them to ground.....open circuit there knackered.....i got 3 ohms to ground on my merc for good one  

Except, being designed by an imbeccile, all the rather intake has to come off to get to the little beggers.  .

Have I mentioned how much I hate BMW?

Hows the fuel pump on the engine, is it worth using the old one

Do you know waht a PITA they are to change on old tractor engines?

No - only seeen new ones

runs of the chains, so all those covers off, cams/cranks locked, retiming afterwards...

Maybe a silly question but, Are all fuel lines sealed and not leaking otherwise air will get in to the system and give the appearance of running lumpy and missing..

They seem tight.  Those not familiar with this lump, there is a fuel line from the pump for each injector.  Did wonder about an airlock in on or 2, but it normally clears quickly in my experience.

I tend to agree with James, did you purge/bleed the fuel system? Once it is running the glow plugs don't do anything :-/
Good luck, and i look forward to the continuing story

Its quite cold, so without glow plugs, you cant get the heat in to get that cylinder running.  The amount of dirty smoke leads me to think it is fuelling ok  :-/
