Omegatoy is popping round for a couple of hours around midday

Today could be make or break day for the tractor  :-/

Fingers crossed, you deserve a result out of this

Why couldnt the weather have been like this last weekend   How is it going today any luck or do you want Smithys numder yet  

[Omegatoy]

dunno where the boy is or what he is doing but we reset pump timing and got rid of all smoke and the heavy diesel  knock!!! this was after changing the injectors which made absolutey no difference to the way it ran so bit the bullet and played with injector pump timing, had it running with no inlet manifold on and no throttle body and blanking the egr pipe by holding some tissue over it, lo and behold it run well,then had to fly and leave the boy to reassemble the engine, and since then havent heard!!!

I thought all tractors were noisy ......  much prefer the purr of the V6  

but glad its runing at last .. a noisy engine is better than a dead engine  ...

Glad the old girls running at last   pump timing I was fairly close then   so its not going to smithys then   Bugger I was going to ask for the boot spoiler and grille for mine   Seriously glad its going now   its taken a fair amount of work to get there but I bet its a weight off your mind now

Omegatoy popped bround earlier, as he has said, and after swapping 5 of the injectors (would have done 6, but Mr Strongman broke my brand new tool ) and finding that made no difference, we decided to mess with diesel injection pump.

Undone the 2 bolts, but we couldn't shift it. So we undone the hidden 3rd bolt and we could adjust.  Move about 1mm, big improvement. Quieter, started on the button (this is with intake off as well!).  So we decided to move more. Another 1mm, and it was better again. So another 1mm, slightly better again.

At this point Omegatoy really did need to go - only 2hrs after his original curfew time   - I hope he didn't get in too much trouble.  If he now speaks in a high pitched voice, I'll assume Mrs Omegatoy was not best pleased.

Put it all back together.

We then had people around, and had a BBQ, so left it for a few hours.


Just been out for a test drive, very noisy at first, including a strange rattle until it warmed up. Took it round the country lanes first, then for a thrashing up the A43 to towcester, obviously keeping to 70mph . Temp stayed low, and little pressure in system when I returned (after stopping at Tunnie's for a chinwag).  No obvious water loss. Little bit of noise still when foot down, unsure if diesel noise, or tappety  :-/.  Little down on power as well I think, but then I've been using the MV6 for 2 weeks, which will always be more powerful....

So still a bit more to do on the engine to get it right, but its much, much, much closer.  Any diesel experts who know how to adjust pumps fancy a little look - now it goes, I can drive it places? Not sure we can get it perfect by trial and error (I'm not as good as Mr DTM!).

Sassanach also turned up today, which as a pleasant surprise

Under load, its a loud tickety noise, but I would need someone who knows about such things to confirm...

[Omegatoy]

hmm kind of expected that when we moved the pump the extra mm and it didnt improve it any further, should have reset it to the second or third position it was best there i think, did you try a hot start? was it ok? how much smoke now? damn i can see me going round again to get it dead right!!!
mrs Omegatoy wasnt to mad really   as she informed me that i had bought her a new phone!!!! for being so late, fancy hurting a guy in his wallet? thats only just slightly better than the ear bashing i was expecting!!!

wouldnt mind betting its something to do with the wired injector not being as tight as it should!!!
