I've got a bedford tk 330 n/a which chuffs out white smoke when reved. i checked the timing as in manual but pump is fully adjusted where it bolts to compressor, is it possible to move the pump on the splined shaft or has it got a master spline?could there be another reason for this smoke?

Black smoke = blocked air filter
Blue smoke = oil problem (turbo,piston rings,valve seals)
White smoke = engine gubbed - recon required
