Oil is leaking from the top of the housing that the oil filter screws into. What I would like to know is, what is the name of that housing and can it be repaired or replaced? Also, what would be a ballpark figure in the cost for both?
I know that the filter was not loose and the only time that the oil came out was when the engine was running. The oil was like bubbling from the top of the housing where the filter screwed into. Also it was bubbling with some force and stopped when the engine was shut off. Any ideas of what the problem might be?

There is no oil pressure when the engine is shut off. This is why no oil comes out when the engine is off.
The oil filter threads onto a nipple that is threaded into the engine block. Unless there's been an external oil filter unit installed.

I know this is an old post, but in case someone else is reading this.
The oil filter is screwed against the "oil cooler". The oil cooler
has an oil seal that is sandwiched between the cooler and the mounting
Over time, the oil cooler seal gets brittle & cracks. Resulting in
a very fast oil leak when the engine is running.
To replace the oil cooler seal, you need to remove the oil filter, loosen
and remove the 27mm nut that secures the oil cooler against the
Lower the oil cooler off of the mounting tube and then replace the
oil cooler seal.
