Still don't understand why the intake was replaced. The only oil leak that would be occurring at the oil cooler would be from the fittings(banjo style bolts w/crush seals). It would need confirmed that this is leaking before I would go back into it. There are several things that can leak, most common on the upper engine is the cam covers, but I have seen leaks at the oil cooler lines one time, and I believe it was loose fitting bolts. Keep in mind that if it is leaking there, this is oil under pressure, and it will be leaking pretty good when running. With some extensive visual inspection, and/or adding ultraviolet dye to engine oil, the source can be isolated.
