The car used to smoke blue until it warmed up. Since then I've advanced it and this has completely disappeared.
Thats good to know about the diesely sound lol.
One other thing, when started at temps below say 10 degrees C, the engine fires instantly and idles fine however it kind of misses for 3-7 seconds. There is no smoke but the engine kind of jumps a bit though the rev counter stays still. I'm thinking this may indicate low compression as it did it before the new head and new injectors. Having said that the bores looked pretty much brand new so I can't really understand that.
I'm pretty happy with the timing now and as it doesn't smoke whatsoever I may turn the max fuel screw ever so slightly just to maybe get a tiny bit of smoke when it is being floored. Don't worry as I dont have a egt gauge, when I say slightly im mean very slightly as Ive sunk a rather large amount of money into it.

Edit: Stroke of luck, the thread below this is about exactly the missing problem. Think I will head off to get a new mann fuel filter on monday (only one I havent replaced since I got the car). Do I have to fill the filter up as I dont have any diesel in a jerry can or could I just fit it and crank till it fills?
