I started the Mazda today and immediately it starts smoking from the front of the engine. I got videos of the smoke, I'll post the link to them. I started it the first time and there was smoke then the second time there was SMOKE and then the third there was only a light mist of smoke unless I revved it. The header seemed to be very hot considering the temp had barely passed the cold mark but I didn't think to check the temp with my IR gun. It looked like oil was leaking out of the gasket between the upper cat and header. Idk if the cat is clogged again causing the header to get so hot although it's only 4,000 miles old. Hopefully, all the oil on top of the piston is burned off so I can pull the plugs tomorrow and check for oil.
