300 SDL hed gasket or turbo seal ?

[atkun]

my 300 sdl got the blues I was driving back from FL and suddenly a big white smoke came out from my tailpipe and smelled like burnt rubber the temp gage did not go up and the car was still driving ok . I had to tow it in to a small town and leave it there being Sunday and pouring rain . There was also a lot of oil around the turbo and exhaust pipe area plus on top of the valve cover close to the firewall. Please help me find the problem or buy this car as is .The car is in WV ZIP 25938 place called Victor
