Tons of smoke coming from the engine and exhaust

[xFidelity240sx]

Car is an 89 hatch with a 92 KA24DE. Headers, s*** intake, and exhaust (no idea what it is). I went to autozone to get new oil and coolant, aswell as a N0X cleaner and MAF cleaner. Car has tons of power and idles fine at times, sometimes it will bog down after I rev it (up to about 2-3k) but generally the car feels extremely quick and picks up well.

Tons of smoke pours out of the header, and the exhaust. I need new gaskets on both. Header is a hotshot header.

I assume my injector(s) are wide open and I'm dumping fuel and burning oil. My oil smells like gasoline as well. Valve cover gasket isn't leaking coolant. Head gasket is good, no overheating or milky oil. I have no idea what to do... I'm going to take it to emissions tomorrow after I do the oil and all that. But I do know I have multiple exhaust leaks. Header also has a bolt missing

"Oil smells like fuel" - you could be mere moments from spinning a bearing. Fuel dilutes oil and it doesn't take much to allow metal-to-metal contact in the main bearings.

I would advise you to change your oil and fix the injector issue (MAF wiring or leaking o-rings are #1 & #2 causes) before you drive it any more.

Good luck!
