Right then chaps, need to pick your brains. sorry if this is long winded but need to give all the background.
just got the van running after the rebuild. New piston rings, bearings, crank seal etc, new head, new clutch new oil/air/fuel filter etc etc.
had some damage to the diesel pump when the engine fell over. It bent the bracket/arm for the accelerator cable. Replaced the arm but the it was pissing diesel out of the spindle.
I decided i had nothing to lose and stripped the pump in situe. Turned out the brass bush/collar thing had been knocked in slightly so tapped it back out, rebuilt and hey presto, no leaks.
Took the van for a run and the engine sounds spot on but theres just no power. Now before the 2.4 bashers and the TDi boys come along, this van had a lot more power before the rebuild. Its struggling to hit 50mph on a long flat road.
its as though the vans restricted and not opening up enough. Id read about getting the spindle in the wrong place when people have took the arm off the diesel pump so i slackened it off and moved it round one spline. started the van and it was revving the balls off it. so i put it back.
Ive taken up all the slack in the accelerator cable and it has improved the feel of the pedal, but not the performance.
The timing was set up by my uncle the old manual way, done properly locked in place, pump moved, depth micrometer in the end of the pump, set up to 0.9 i think it was (dont quote me on this) by the book. Engine starts first turn of the key, doesnt sound lumpy etc.
So, what could it be.....?
What would the effects be if the air filter wasnt fitted properly and it wasnt getting enough air?
what about if there was air in the fuel lines? (havent tried cracking off the injectors since taking the pump to bits but it was done when the pump was fitted)
fuel filters brand new so cant see that being a problem.
Theres no travel left in the pedal so even if i adjusted the lower screw on the pump to allow the arm to open up more, the pedal wouldnt allow it.
Im stumped
any help much appreciated
Cheers, Nick
