Why does my truck skip and pop on one side and blows black smoke??
buy a cummins
No. Black smoke is created when your truck is running Rich meaning that you are getting to much fuel the black smoke is just simply unburned fuel
possibly needs a new carborator
What kind of solvent?
It is completely normal for a diesel to smoke black. But, if it just now started to smoke black and everything on the truck is stock, go get it checked out by a mechanic. You could have bad fuel injectors or a dirty air filter. Start with the simple stuff first. And, I'd say from it being a 2004 Powerstroke 6.0L, that your injectors are probably bad.
Could be a diesel? If not then replace your oxygen sensor on your exhaust. A bad oxygen sensor causes the exhaust smoke to be dark in color.
your truck blue smoke when it burns oil, or transmission fluid.
valve seals. Can be replaced with engine in truck & heads do not have to be removed.
if its white smoke ,it could be ablown head gasket,if its black smoke, its your carb. running rich,or your piston rings are bad,on mine my 2 front plugs kept getting oil on them.head was good but rings were bad,got a reman.. from jasper and put a webber 32/36 and its so bad now...
it can be unburned fuel damaged turbo charger etc. light amount of smoke can be normal large amounts = problem.
Start your truck cold. If a lot of white smoke blows out that is a slight indication, but not always. Pull out your spark plugs on the side you think you have blown and see if water pours out, if water comes out from the spark plug hole, then yes. You've blown a head gasket.
