I need help. My truck is messing up alot. I was going down the road, and it started to sound like my cadi converter was gone. I poped the hood when I got home, pulled the throttle cable, and white smoke came from the back of the motor. I checked my oil and tranny fluid, and all seemed fine. Any ideas?

 

As a guess it sounds like you might have blown the head gasket and cracked the head. But that's just a guess, you really need more info. Check your coolant level most importantly.

And when you say it was like the converter was gone, do you just mean it got louder?

Does the truck idle rough?

 

The coolant was a little low. And it did get louder, sounded like I had duel pipes but under me, not behind. It sounds like the truck is gargling after you rev it up.
