One of the reasons the HO72 leaks is because the bolt holes go right through the housing. This is on both sides..the cover and the third member.(axles too). Drain the oil..pull all the bolts and put gasket sealer on all of them (the threads). The lower bolts will leak more because they are submerged all the time.
When I swapped to the 14 bolt this is one of the improvements they made..none of the bolts see oil.(among other things).
