As far as I know, you can pull the engine oil cooler without dropping the engine, so at least you will not be inconvenienced too much. Before you do anything, you should clean the area around the leak so you could definitely identify the leak. Then, I would drain the engine oil into a clean pan so you could re-use. When you remove the oil cooler, you'll be able to see if you pinched the seals. I did mine a few years back, and it was pretty straightforward to replace the seals as they only fit one way. Are you sure it is not the oil hose that is leaking?
