The other night i was at a stop light and out of nowhere, my truck tried to take off even with the clutch pushed all the way in. I managed to pull into a gas station and i turned it off. I went to try to turn it back on and the key would not turn. I popped the hood and checked a few things and noticed that the engine oil was low. I put oil in and tried to start it but the key still wouldnt turn. I put metal to the starter solenoid and it started up. It did not want to go in gear and id have to slam it in to get it into gear. Anything over 5 mph the truck started bouncing. Came back the next day and started it up and it started blowing a lot of white smoke. Id hit the gas and a huge white cloud would come out followed by a black cloud. I put it in gear and it ran fine. I turned my TS switch to stock and made it home fine. Rode around some more that night and everything was fine. Later that night i was on the highway and the clutch petal shot to the floor and i heard a some loud noises and my truck was just going about 10 mph. I put it in neutral and it wouldn't go back into gear. Pulled it home and started it up and the clutch is still to the floor. Doesn't seem to matter if it is to the floor or not. Even when its in gear it won't go anywhere. Also a squeeling noise now seems to be coming from the turbo and there's more white smoke when i start it or hit the gas. What is wrong? (Besides the fact that i bought a ford)
