Thanks - I'm hoping luck will turn with this project....

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!!!

Omegatoy

Still noisy, not sure if still diesel knock, or tappety....

Good news at last TB, you've earnt it.

what compared to how it was or after we did pump timing? full explanation required!!!

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

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!!!
