well, i just finished up installing my new valve cover gaskets (i used the Fel-Pro ones from AUtoZone). i had oil in the spark plugs (in #6 and #5), so i removed them all and let any oil drain back down. then i removed the spark plug galley and cleaned it up, along with underneath it. installed new plugs and wires, put everything back together and tried to start the Supra... ...well, it made a turn-over sound, but wouldnt fire, i had to turn the key about 5-6 times and it finally started. white smoke cam pouring out, like James Bond smoke screen thick. WTF? i looked under the car and it looked like the oil was coming out of the exhaust (i have a DDP on and no cat. back). so i took it for a 15 min test ride, staying out of boost, i am still breaking in my new clutch, and come back and check it, not smoking nearly as bad, but still a little there. what would cause this?
