Message 90n/a been having an exhaust smoke issue for quite some time. I have a coolant pressure build up when the coolant system is closed. With the radiator cap removed, and the coolant is full in both the radiator and overflow bottle, the car runs fine, except for the exhaust smoke. The smoke is only coming from the drivers side exhaust (ALOT!!!!). With the car idling, the coolant flow looks nice and consistent. There are no air bubbles in the system that I can see when the radiator cap is removed. The heat works fine also. When I replace the radiator cap, after about 10-15 minutes, the upper radiator hose begins to swell, the temperature gauge begins to increase, and eventually the upper radiator hose pops off the radiator, blowing coolant everywhere. This started happening after I changed a fuel injector (Driver Side center cylinder) and all plugs. After I changed the plugs, Injector and started the car, I heard a couple of rattle noises, the it stopped, and the car started smoking (White). When i checked the old plugs, I found piece of the of the outer white ceramic had broken off and maybe fell into the (Driver Side center cylinder), that's probably the rattle I heard when I started the car. The car runs and idle fine. If I drive it for a while the smoke will dissipate. After not running for a bit, it will start smoking again. Thanks for taking the time to read this and I appreciate any help or suggestions.
