so out of nowhere i start up my truck put it in gear and hit the gas and right after i do it smells like something burning and theres a little bit of smoke coming from under the hood? teh smoke comes out of the passenger side headlight, it only does it while under load though like if i drive or just while we were checking i had my foot on the brake and gas to put it under load. i think it could be blowing from anywhere because the fan blows to that side....so me and my friend and his dad tried looking to see where it comes from but we cant find it and it smells really bad also any ideas on wtf might be wrong???

 

Did you spill any oil or coolant in the inside of the engine bay?

Do you have anything lying on the exhaust manifolds? Plugwires, hoses, oily rags?

 

nothing at all....i checked everything i have my wires tied up outa the way and i havent spilled anyhting on it.....its not a burning oil or rubber smell its really weird i couldnt even explain it

 

Did you do anything to the truck recently?

 

sounds like an oil leak to me.

 

From the passenger side headlight makes me believe that you've got a coolant of tranny oil leak going into the radiator. It's also possible you've got an exhaust leak, but if you can't identify the smell, we're in for a long guessing game.

pull the tranny dipstick and smell it and see if that smells familiar.

 

Leak in the hose form the radiator to the overflow catch?

 

i have no clue where its coming from....and i havent done anything to the truck recently other then clean it.
i dont know what it smells like...its definitely something burning but i dont know what it smells like soem sort of chemical smell, and its really annoying not knowing what it is lol

 

Try acquiring some of the basic automotive fluids, trans fluid, radiator fluid, motor oil, windshield washer fluid, etc. Then indvidually burn themin acontrolled setting. Tell us which one it smells like.

 

did you clean the engine with a degreaser and not get it all washed off? WD OPN Throttle has a good Idea, you can test that pretty easily if you have a torch.
