oil leak from a part i cant identify!

[vrex]

Hi all, as previously mentioned, i had an oil overfill situation. this has been corrected per Loren's advice by just draining via the oil filter a few times. however when i first jacked my car up, oil started pouring from somewhere near the header/cat pipe gasket on the drivers side. upon closer inspection, it turned out to be coming from a bolt. i cant, however, identify what this part is. please see the attached pictures. if you were laying under the car, looking up past the header above the precat 02 sensor, you would see this part. do i have a major issue? I'm hoping this is a part related to the AOS, though i havent seen the AOS yet (ordering serice manual so i can go through schematics more thoroughly....). please see the attached and let me know what you think. Thanks!

I think it's your engine/motor mount that is leaking and not the engine itself, especially if you jacked up the car using the engine jacking point, it may have tore the mount open:

The engine mounts should be replaced in pairs.

Good Luck,

That does not not like engine mount fluid to me. Engine mount fluid is usually greenish-blue.

You need to check on the top side of the engine for leaks. I would feel under the filler hose (they get old and crack - but that usually gives you a CEL). Or look at the temperature sending unit - the can come loose and leak too.

Looks like you ruptured a motor mount. Did you use the engine as a jacking point?

It's a engine mount. If you look closely at the attached pic it's seems to be coming from the internal area of the mount. And as already pointed out replace in pairs.

It clearly looks like the mount is leaking but thats got to be engine oil. You need to clean the top of the engine throughly and then let it run so you can observe the origin of the leak. If you don't see any oil up top than it must be a mount but I really doubt it.

ill clean up the area and check it out. if engine mount fluid is greenish in color, then this is definitely not engine mount fluid. unless of course, engine mount fluid can go bad and look like motor oil. ill do some more investigating. havent driven the car since this happened yesterday, ill keep note of any undue vibration or harshness.

If it's a collapsed mount than you should notice movement in the shifter or a clunk when shifting under acceleration.

I've also seen a very dark-purplish colour leak from the mounts.

there is a touch of a thud when shifting under certain conditions. it seems to me to be more of a smoothness with shifting issue caused by me, or so i thought initially. if it is in fact a failing motor mount, then that would explain it. shifting quickly and rev matching up shifts eliminates it, though it isn't as noticeable under downshifts regardless of rev match or not.
