Hey, Ive been looking around for the Intake and exhaust valve clearances so I can get the diesel car running quicker. Does any one know what the procedure is to adjust the valves?

also, How does the glow plug circuit work? Is it supposed to run a 6.5 volts?

Basically Ive got an old 220d with 10,000 miles on the odometer... I have no idea what the actual mileage is?? But it is a pain in the ass to get going in the cold.. Yesterday I got it running by moving around the insulators on the glowplugs, and cranking for a while... once its going it seems to run good, kind of smokey under a load, but not to rediculous. once it was warmed up it would start right up.. Kind of interesting clue is that yesterday when trying to get running it would kinda sputter and run for a couple seconds with no throttle reaction at all, it would kinda sound like it was choking when the throttle was hit. I cracked the injector lines and it started? Any other ideas on what the hard start problem could be? thanks -Chris
