Just a thought: the timing on most diesels will tend to become retarded over time, as the gears wear. This is evident from a loss of power and loads of grey smoke. The timing can be advanced to a point where there is a lot of extra power and the smoke clears, but;
How can you tell at which point the optimum setting is reached? what are the signs of timing which is too far advanced, and what are the long term effects, if any?
Would appreciate any info that anyone has - I'm on a mission to squeeze every last drop o' power from the old powerplant
