[QUOTE="skidsteer.ca, post: 2177, member: 307"] There should not be much air coming out of the blowby tube either, and what does come out should come at a even, steady rate, a puff, puff from the tube indicates one really bad cylinder. If you have changed you fuel filter, (and checked that you have good clean fuel), and you air flter is clean(a plugged af make for black smoke, with power noticabl down ,the smoke would be noticable to) Genrally bad injectors make for hard cold starting and greyish smoke, smoke does not go away quickly (ie 20 30 seconds) during warmup. To test glow plugs Hook a voltmeter to you batt and see if the volts drop when you hit the glow plugs (a 1 v drop is about right) if no drop you may need a relay somewhere. indicates no power going to you glow plugs. Use a test lite to verify by probing the glow plugs. Finally unhook the bar between each glow plug, take a test lite for trailer wiring, hook the ground clamp to the + on you batt a probe each glow plug(where you removed the power strap), the lite should come on as it gets it ground through the glow plug element, no lite = burnt out glow plug. If you blowby is normal, low power is likely fuel related, the glow plugs are only a starting issue, Ken [/QUOTE]
