Is the part number the same for both sides?

zaaahhhhh! So, I changed out my passenger side gasket today (with a lot of ****ing around to get to the back bolt), but I COULD NOT get to the back bolt on the driver's side. Bracket was definitely in the way. It offers NO clearance. I spent an embarassing amount of time trying to remove it. So now my car sits dead, as I destroyed the gasket trying to remove it (thinking that would buy me some clearance and spin on the bolt).
Tomorrow I'm borrowing a car and am going to buy a flex socket, a tiny ratchet, and a long-ass extension. Maybe that'll get the job done. My sockets didn't even really want to fit on due to lack of clearance between bolt and plastic housing.

Just love how they built these things to be easily serviceable.

I just did mine today. I also had the problem of getting the one bolt that is closest to the front of the car off of each of the plastic housings because of it being right under the GBOD and not enough clearance on the plastic housing. A minute or two of brainstorming and I created...the oil separator cover bolt removal tool!

Unfortunately I have no pictures for you but essentially what I did was find a small 1/4" drive, 10mm socket that had no clearance issues with the plastic housing. I then took an allen key (just a single key, with a 90 degree bend), stuck the "small" end of the key into the socket, and then turned the socket with the "long" end of the key.

Your obviously going to need a "thin-walled" and "short" socket that will fit over the bolt without bumping into the plastic housing and wont be tall enough to get into the way of the GBOD. Then you need an allen key that is large enough to fit snug into the socket (as if it were a socket wrench), yet wont be too big.

I had both and it saved me a headache and a trip to the hardware store.

Oh, by the way, I replaced mine because one of them was weeping oil badly. I HIGHLY recommend changing these when you get a chance, there was SO much gunk underneath mine (refer to the first page for an example image.) I have a much smoother idle as well.

Yeah, mine are a bit gunky. Not as bad as the OP, but there is some gunk. I'm at 75k miles. i just wiped mine out with a rag to clear the gunk. I thought about soaking the gasket in Rotella before putting it in, but I don't think it matters. It'll get plenty soaked when I crank it
Interesting idea, DeathPool! I dont have any sockets that fit that description, so I'm still going to the hardware store. I'm really hoping a flex socket will work well enough. I haven't been able to find any specifically thin-walled sockets or short-profile sockets like mentioned on here.
I'm hoping this will work:

That, plus a 10-inch extension or else a thin profile ratchet.

I got mine swapped today on the drivers side.
The trick for getting at that inaccessible bolt:
10" wobble extension + 10mm flex socket
It worked like a charm!

I been hunting down an oil leak for over a month, this passenger side oil seperator seems to be the most likely culprit. How much did the dealer rape you guys for a pair?

I have 132K miles and haven't replaced mine either... though I do use fujibond to seal them up, as they were weeping.

They weren't much. Maybe 16 or 20 for both, I think.

As I've said, any leak from these is also possibly a sign of a small vacuum/pressure leak. It's a good idea to replace them.
My driver's side was missing, so that was a huge difference, but I decided to also replace the passenger side.

At the time I was watching the short term fuel trim like a hawk (was fighting the bank 1 lean code), so I definitely saw before/after changes to the trim. Before the passenger side replacement, the trim was hovering in the appropriate range, but only on the positive side. After replacement, I started to see negative numbers too, It became centered on zero..

Just changed mine. My drivers side one (right hand drive) had been leaking and had a bit of gunk in it. Nowhere near as bad as the OP though. Passenger side wasnt leaking but i replaced it too and it was clean except for a tiny bit of oil.

Greetings,
Sorry for bringing this post back from the dead, but I just found my passenger side Oil Separator gasket leaking, as well as oil seepage around several of the passenger side valve cover bolts. As all of the bolts were tight, is this a sign of the engine being over-pressurized, or do these items just leak when they are at 226,000 miles?
Otherwise than that, the engine is oil-tight and runs just like new.

The gaskets are rubber and go bad over time. I'm surprised yours lasted until 226k. My passenger side gasket started leaking around 75k. Replaced it and no more problems.

Sounds good, but why do I have a leak around the valve cover bolts as well?
Is there somehow too much pressure being built up in the area under the cover?

There is seals on the valve cover bolts that can go bad.

OK, good to know. I'm still wondering about a pressure problem, but not sure what could possibly malfunction to cause this. Normally I would look to the PCV valve, but I read in these forums that a bad one shouldn't cause this problem.

I know right? I'm a lazy mofo to do it. I've had the gasket sitting in my tool chest since forever.
