wrong oil... try some kendal nitro 60 weight or valvoline 50 weight plus one bottle of LUCAS stabilizer in place of one quart of oil and call me in the morning... also, change your fuel filters regularly... and everyone should have a manual for their vehicle, and a professional shop manual should be available at the library in the reference section for FREE...make copies of the right pages and fix your vehicle like a PRO! :) good luck Dave :) white smoke usally means water in the cylinders it could be a blowen head gasket Rooterman2 . agreed. white smoke is generally water, blue smoke is normally oil, and that black smoke usually means you have to much fuel entering the combustion chamber.
water
yes...the lack of air would causes excessive fuel which would cause black smoke.
unburnt fuel
Highly unlikely. Water entering the system is the most likely cause.
Black smoke, from any diesel, is the result of partially burned fuel. Overfueling will cause black smoke.
a dirty air filter or a dirty fuel filter will cause a diesel to smoke
In a diesel engine, blue smoke is an indication of oil being burned. Black smoke means that there is incomplete combustion of the fuel. White smoke can be seen when raw diesel fuel is not being burned.
when it get really humid or very cold
It can.
Dont filled oil so that no smoke
with diesel at nearly $4.00 a gallon why would you want to. In most states you can be cited for excessive smoke.
The cause of white puffing smoke in a diesel is the crack pipe ventilator seal. Fix that it keeps the crack inside.
