have you tried that injector yet?

No, though I have measured the DC resistance - 0.073 ohms, compared to 0.075 ohms on the original injector on the donor engine.

Well seeing as you cant measure resistance to that degree of accuracy I would say thats close enough!

Exactly....   ....so not worth swapping out that injector?

just unplug it and see if it makes any difference to the running of it !!! (dont make me come down there again,)to many gatsos on the a420 and you would have a sore ass after 190  miles on a chelsea tractor

The thing is a bugger to start today. Tried unplugging, absolutely no difference, still couldn't start (or keep it running more than a second or 2.  Did eventually get it to run (with it plugged in), but badly.  Worth unplugging it with it running? The fact that it didn't help the awkward starting made me think that wasn't the issue?

Had a pleasant surprise today, Sassanach turned up to lend a hand with the tractor . Also Laidback66 made a flying visit to laugh at it.  I had the last laugh though, as he left with a face covered in soot

I think Sassanach has come to the same conclusion as I have - the car is jinxed.

He tried it with the fuel line disconnected, and a tube feeding the injection pump in a pint glass of diesel, which rules out an issue with fuel delvery to injection pump. We tried swapping the injector with the feedback over (actually, I may have done that before anyone turned up), tried it with it unplugged (than caused a change in engine note, and brought on EML), played about with pump timing (got it running quiet and smooth, but still smoked badly).

As it was running quiet and smooth, we decided to take it for a drive.  I think Sassanach laughed when I put the tow pole in the boot.  Fortunately, didn't need the tow pole, as the thing only just made it off the driveway  .  Those that know my place will appreciate how hard it was to push it back on up the slope  .

We could get it to start, but as soon as gear selected, it dies - even if you drop it in gear at 1500rpm.

We decided to call it a day, and think about it....


And to add insult to injury, the tractor has a significant oil leak from the sump plug, and an even more significant one from the gearbox  .   Words fail.


So a massive thanks to Sassanach for coming to help - it is a significant distance to travel.  A fresh set of eyes is welcomed as Omegatoy and I have run out of ideas...


Time to get bladdered now

I am no more qualified than anyone else that has already looked at it... but I'll happily spend a weekend with you if you fancy a play (which I doubt you do right now!!)

The oil leaks - sump plug - is this just a case of a crap washer, or is there a thread problem? And where abouts is it coming from, off the gearbox?

I feel really sorry for you... I do know how it feels when a project goes t!ts up...

Leak from sump may be a crap washer.  The sump plug is fubar (someone has mashed up the torx), so needs replacing.  Trouble is, I don't want to drain it yet, as it has all the lifter treatment in at the moment.

The autobox, not checked, but looks around bellhousing. Defo autobox fluid - a nice red wine colour.

Hi TB words fail me mate  Flow valve is different from timing solenoid spoke about earlier. Can you let me know what pump you have on now and what was on previous so i can delve into my archives and get an idea of what i'm looking at, cheers.

I think compression checks should be next port of call done through glow plugs, as timing etc doesn't appear to make much difference. Trying to persuade SWMBO to let me come up not this weekend but next, not sure how that will pan out as i don't see her or chillblanes as much as i would like now, but hopefully will get car sorted before that

I don't have my compression tester, its loaned out  

I have not changed the pump - so it is the one that came with donor engine. Looks like changing pump needs special tools.

The pump, not sure who makes it, but is the same I believe across all these engines (BMW M51 TDS), as fitted to Omegas, BMW, some Landrovers etc.

I have had 2 people who know diesels (maybe not true 'experts', meaning no disrespect) baffled by this. Both have commented that I'm right about the car being possessed

Cor I think your almost becoming proud of that fact  Could you get me pump details from tis not serial no's but model no's Most of my info is not car/manufacturer related but pump type. Also although resistances the same on injector, spray pattern is probably different on later injectors due to redesign of swirl in piston combustion chamber.( I'm assuming its an indirect diesel not a direct injection ) But as misfire not regular and engine generally rough you may be okay to leave for the minute.
Got to go now but will contact tommorrow for any updates. Keep smiling Its only bits of metal and wiring, I hope there is no personal vendetta on the cars part.

There is very little info on pump in either Vauxhall TIS/EPC or BMW TIS, certainly doesn't say make. Guess its either BMW or Bosch, but do not know, nor know how to find out

[ffcgary1]

TB, please refresh my mind as to why you did not just change the cracked head on you original lump.IS this still not an option to go back to the orig engine. it does sound as if the engine yopu got is a duff unit. is the seller of the engine cosher.poss head off to check internals is looming.Good luck jamie.

[JamesV6CDX]

Compression tester can be with you pronto!

Can it be used on diesels, though?

[JamesV6CDX]

Garry...

It would appear that it was more economical just to hoist a known good lump in - head removal on these isn't easy.. and god knows what would have been found !

I just hope the lump is good
