all the lines are new i replacced them and i did a check with warm soapy water and didnt see anything.
it is white smoke and smells a little rich. the plugs smell like strong gas. but they are dry.
also it is a 94 blazer4.3 vortec motor.
brake fluid is fine i just replaced a cou7ple lines a few months ago. all the wheel cylinders and calipers are good.
