Possibly front timing cover gasket, front crank seal, oil filter/bracket, turbocharger drain hose?

I bet if you take out your fan and look the crack will be right there under the fan. Or what happened to mine was some of the bolts vibrated loose a little bit and that made it leak. Is the belt sqweeking or is there oil all over the front of the motor.

No it wouldn't make any noise. Also it could be the bolts fell out or the case.

You will have to get some of the oil off and get a big light and look really good if its the killer dowel pin you will see the crack. Mine cracked and the bolts vibrated loose.
