this is gonna sound dumb as heck by is there any way to get a gas engine to blow smoke? without hooking up a fog machine to it?

 

Black smoke? Like a diesel? Or just smoke in general? I guess if you wanted it to blow smoke a smog machine is the only way for a gas truck, unless you're burnin oil really bad

 

Why would you want to do that? Most people go through a lot to get rid of the smoke.

 

if it is black smoke then you are dealing with an overfueling issue, white means coolant is leaking into the cylinders (head gasket, cracked head or block) and blueish smoke means you are burning oil. are any codes being thrown?

 

Yes, a can of Seafoam in the intake/vaccuum system of a hot-dirty engine. Let sit for a few hours and then drive it around for a while. It will smoke so much you'll think its on fire, but only for a few miles and then it will stop smoking and generally run better. If that's not good enough for you then try manually shifting with your foot to the floor and miss drive momentarily and this will more than likely blow your valve seals in which you engine will smoke from this point until you have your heads rebuilt. Don't like that either? Pour oil on your hot exhaust, that will definitely work but doesn't smell very good. I could go on all night but ultimately what you want isn't a very good idea.
