Hey all,
I need a little help figuring out what the name is of the part that is leaking oil from my 04 Mustang. Upon jacking the car up and looking at it today, the leak appears to be coming from a small threaded cylinder (maybe an inch in diameter) right above/next to the oil filter itself. The threaded cylinder has a hex keyhole in it and is currently tightened. Upon searching the internet, the only similar part that I came across was called an oil bung, but since I only found that name in one or two places, I wasn't sure that it was actually called that.

When I changed my oil a month ago and noted the leak for the first time, I tightened cylinder a bit and then made note to check it a week or so later. Relocation and starting a new job made me forget, so I just remembered when I saw more oil stains on my driveway recently.

I'm not the most savvy car repairing individual, but if all I need to do is replace that part, I think it should be easy enough to do. Does anyone know what the name of the part is, or has anyone else had an issue with this part leaking oil? How much did it cost you to find the replacement part and fix?

Thanks,

Id pull it out and wrap some teflon tape around it during your next oil change. That should clear it up.

I got this same issue, can that part be taken and sealed by teflon tape?

I would do as BabyGT stated. But remove it slowly in case it holds a spring or mechanism in place.

I tried searching the forums for the same issue, looks like nobody has tackled this. I'm thinking of just replacing the oil pump but the manual seems to be confusing. It looks I could I just unbolt the pump (6 bolts) but it says remove the front cover too. I have no idea why it needs to be removed..

I'll try tightening that power steering hose connection, it looks like the PO damaged the teflon o-ring during installation.

to answer my question, I went to a junkyard and tried pulling out the oil pump. it's a very straightforward process, just remove the oil filter and take out the 6 bolts (4 #10 and 2 #8) the plug has a rubber/plastic gasket/o-ring that turned very hard. It probably shrinked and caused the leak. In my case there's really no need to replace the oil pump, just take our the plug and replace with new o-ring and coat it in teflon.

What is accessed by that plug? For future reference.

lincolnshibuya

nothing, it's just a hole that goes through the other side. The rod that turns one of the gears on the oil pump stays in the engine when you pull it out.

I assume that some accessory could be use in lieu of this plug, a cooler or extra oil passage I guess.

interesting. may be able to plum it for remote oil filter.

You say straightforward, but that filter looks like it had a different story to tell...
