I found an image on the forum that showed the accessory case of a Lycoming engine with specific locations for connecting the oil cooler lines. My engine is an IO-360-A1A and I'm having trouble removing the plug that is located at one of the locations so that I can install the appropriate AN fitting. My question is (referring to the file linked to below) if it would be acceptable to use the #2 opening (located behind the tach drive--there's a plug sitting on top of the opening) rather than the #1 opening (which was identified in the other diagram)? It appears to me that both openings are in the same oil passageway in the back of the accessory case. Thank you!
