96 suzuki sidekick white smoke coming out tailpipe smell extremely rich like fuel plugs all black and sooty starts to miss not a head gasket not coolant

SOURCE: white smoke from exhaust

Hello;
The white smoke is from coolant entering the combustion chamber(s). Coolant can enter through the water passages sealed bu the head gasket. You have probably blown a head gasket. You should check your coolant level. You may have acracked head if you continue to drive it and overheat. The temp gauge only reads when exposed to coolant, not air. Take out thhe spark plugs and look them over. A white glossy apperance will indicate water in the combustion chamber. You may need to surface the head once you have it removed so that it is flat. Hope this helps.
Thanks;

It sounds to me like you have a head gasket leaking. See if you can get a gauge and check each cylinder. Are you using alot of anti freeze?

It sounds like the rings are washed out for some reason. any chance you filled up at a gas station with water in there gas ? if it was me I would do a compression test and see if it is low , and it sounds like it might be then leave the plugs out and put oil in each cly turn engine over a few times and let sit over night or at least serveral hours , this will free the rings up , fuel and miss fires will wash the rings out and running will get you white smoke , after oil has set in cyl now you have to clean it out if you have qa air compressor you can shoot air into each keeping a rag over so you dont make a mess, and you can keeping one end in hand send a rag down to soak it up, you will most likely have to pull the plugs out and clean them with break clean a few times till the engine will stay running once it stays running it will smoke until the oil is gone but the compression should be back to normal and cleared up it might smoke for over an hour once you get it running you can hold throttle to 2000 rpm as well this helps a bunch. but find out where compression should be and check it . I think some how either the missfire or bad gas. did you replace any coils or coil pack ? is the miss fire gone?

blown head gasket. black smoke means that oil is getting into the cylinder.

SOURCE: white smoke from tailpipe, bad gas odor, what

White smoke and a pungent sweet odor can be a sign of antifreeze in the combustion chamber. Yes it could be a head gasket. Check your oil for signs of water.
This could be a intake gasket, head gasket, cracked head, or a problem with the engine block.
All of these items requires disassembly and if you have not done it before I suggest taking it to your mechanic.
