The oil leak was coming from underneath the oil pan and under the passenger side of the engine. I bought dye to see where it was and emptied out my oil and when I went to jug the used oil notices water/coolant in it cause it was seperating. The engine is a new crate engine from autozone and is only under 3 years and some months old. Any idea what this is from. Please help me thank you. The engine is clean and all I just don't know if I should put new oil in it and the dye and see something I don't want to chance ruining the engine.

You have a blown head gasket. You must be overheating engine. Do not drive it.
Thats what I thought and the thing is the engine never overheated. iI guess I'm just going to have to replace them both and see. I drained out the oil yesterday and then today when I went to open the screw on the pan nothing but water came out. I haven't drove the car since monday when the radiator had a crack in it and was leaking out. I put a new radiator in it and then did the oil and thats when I noticed the water and coolant in the oil when it was draining out.
It turns out it is the intake manifold the heads/ gaskets were fine. there was no problem with them
Good. You got lucky, but the 3.8L engine is notorious for for blowing the head gasket nearest the firewall at around 100,000 miles. I had one come in that had a knock in the engine. Found out the water in the cylinder caused a hydro lock, which bent the piston rod. That little bend made the piston skirt hit the crankshaft.
