Why does water from my radiator leak into my oil pan in my 1996 Chevy 1500?

[Bacdaddy]

the truck runs, but could it be the head gasket? what else could it be? i heard some one mention the crossover?

possibly a cracked cylinder liner

There may be an oil cooler installed on the engine. Above the oil filter you may notice an adapter plate with two lines running in to the rad. The cooler in the rad maybe faulty.
Have the cooling system pressure checked.

it's your head gasket go to the parts store and get 2 bottles of head gasket sealer and pour it into your radiator.

Blown head gasket.

Head Gasket is the problem.
