Message	the coolant galleys in the heads shouldn't be that difficult and cost less than 100. I've never seen a Z32 head crack in this way (that causes oil and coolant to mix). I've seen a turbo cause this problem once. Pressure testing the coolant jackets in the turbo CHRAs isn't that difficult, just requires some plugs and fittings. As mentioned above I have seen blocks with this problem internally a few times. Having a machine shop properly check your block for this problem would probably be difficult for a reasonable price. If you have material and fabrication resources it can be done in a few hours.
