Wierd sound when pressing gas pedal.

Fire up your truck cold, get underneath it, and run your hands closely around the exhaust pipes. Don't touch them, they're hot. Where the exhaust pipe splits to go to all the cylinders, is the exhaust manifold. This is an easy check to do that doesn't require swapping fluids. Swapping fluids is your next bet.

Sounds to me like you have the famous gasket leak.

If it's a ticking sound, more than likley it is your doughnut gaskets. These are the exhaust manifold gaskets they are talking about. Mine does the same thing, just haven't got around to replacing them.
