Sudden, massive oil leak. (pics)

So after some searching, it looks like something in my oil pump has gone bad. Looks like its time to do a timing belt while I'm in there too. Judging by the photo and the knowledge that it only leaks when running and when running its a steady stream of oil, what do you think the failure is? Do I need to replace the complete oil pump or just some o-ring I have read about?

What parts would you buy?

Thanks!

Either the oil pump o-ring to the pump housing, or the pump shaft seal. See:

your oil pump seal is the problem...if the pump when bad, your car will have engine problem.

Im having the same issue also. My concern is that I just had my timing and water pump changed a few months ago. Last week I replaced my serpentine belt due to my compressor locking up. I was wondering if they should have changed those seals when they replaced the timing belt and water pump. i really do not want to go up in there my self.

The oil pump seals are not usually part of a timing belt service unless specifically requested.

As for the OP with 240K mi. I would second the suggestion to do a very thorough job and have all the seals replaced including the oil pump shaft seal and housing gasket. The housing gasket is usually the one that causes this type of sudden large oil leak. You must be very careful with a leak that bad. as you will run out or oil very quickly and you could ruin your engine. Keep a close eye on your oil level if you don't get it fixed right away!
