Pour in UV dye, thread in a headbolt with teflon tape around the threads to prevent the dye from escaping through the top and tighten the bolt as much as you can (keep under the regular torque spec though).... let it sit for an hour and then use a blacklight to see if anything.

But really it's wasted effort; Oil isn't going to get in a fill a hole which was populated by a bolt... there's no room for the oil and it's too thick to press through a hairline fracture at even double the system's normal operating pressure.

Ok cool thanks
