I was referencing the Japanese narrative of the battle in my comments. If you look at the air photos taken of the Wahoo and ships attacking it, you'll realise this wasn't a slick caused by a cup of oil or normal loss. Any sub trailing a slip as large as this could not expect to come home when in the immediate area of hostile and attacking forces. If all our subs belched oil like this as a normal leak, none of them would have come home.

What caused this unusual leak? We'll probably never know.
What weapon actually sunk the Yahoo? Shore battery, air bomb, depth charge, mine?
I personally would rule out the mine simply from reasonableness. Other than that, speculation. All we know for sure is air bombs and depth charges were both used on the boat.
I would further speculate rather than surrender to the Japanese, there was a period during which the boat was still manouverable to some extent and the crew attempted other options, but the circumstances of their tell-tail trail and over-whelming enemy forces brought to bear ended all options.
