I dont do this for ant other thing than the oil change, even though I dont have but 2 neighbors and they are cool (in fact they stand there and watch me while we drink a beer and watch the oil drain forever) but it still looks a little ghetto

Suggestion
for oil changes I read that it's good to roll the rear of the car up on one or two 2X6's on one side then jack the other side???

I thought I saw a diagram of a Cayman recently that had the trans behind the engine (I think the Caymans are mid-engine cars?), so I briefly worried that the 911's somehow changed their basic drivetrain design since when I was into Porsche's last; and that 16 inches in could have meant that the oil leak was related to the RMS.

so what I do is raise the car on one side using the jack points in front of the rear wheel, then when its up high enough to get my floor jack under it I slide it up to the cross member (right where the tranny and engine connect) in the center, and just raise her up...
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Well, my car was delivered last night. 99 C2. Looks and drives fine.
However, this morning my wife called me at work to let me know there were three drops of oil on the floor. The oil spot is dead center, 16 inches in from the rear bumper.
Of course, my first thought (without seeing it myself yet) is RMS.
However, quick question for those familiar underneath of the 996 - my wife said the oil is wet on the engine, directly up from the spot on the floor, where there is "some type of bolt or circle." My wife knows nothing about cars, so I wonder if this maybe a leaking oil drain plug? I'll see tonight, but maybe someone can let me know whether "center, 16 inches in" would be the spot for the drain plug, or the natural spot for an RMS leak to collect and drip from?
I know on my 83 911, this in not where the drain plug was, but rather, this was simply the lowerest spot on the engine where a leak would have ran to.
The car was represented as "no leaks whatsoever" and I have not paid for the car yet, due to my pending inspection. At the same time, I like the car a lot and am looking to be fair. I know an RMS is $1k at the dealer to replace, and a drain plug is probably $20, plus some oil. I was looking to get a P dealership Powertrain warranty, so I am sure this leak would need to be fixed first.
16 inches... wow, she measured it? Is she the measuring type?
sounds like drain plug... but is not to far from RMS either... PPI will tell you better than we can. GL, post pics when you get the p-car.
Thanks. That is comforting. To be honest, by inspection, I mean my inspection, not another mechanic. The car is in great shape otherwise and has been inspected by a mechanic already (i know i know, how did he miss the oil leak, if it was there at the time).
If it is simply the drain plug, that would be sweet!
If it is the drain plug, do you replace the whole plug and washer at each oil change? Or just the washer/gasket, assuming there is one?
Thanks
Yes, she is indeed the measuring type. And luckily, we already had a ruler that was custom made at exactly 16 inches.
Maybe I shouldn't joke, don't want to fan the flames of the old Porsche-driver stereotype (lol).
So I guess if that is where the drain plug is located, and it has no oil leakage above the drain plug when I look tonight, I should be in pretty good shape.
yes... those drain plugs strips easily (not the threads, but where the allen wrench fits into), porsche recommends changing the washers every oil change. RMS leak is located where the tranny and engine meets... if its wet at that intersection you have RMS leak.
Also: there's a Drain Plug mod (better plug with magnet) and a mod for a spin-on oil filter too - if my car stays around, I am leaning towrds those Jake-mods unless I hear compelling reasons against it.
The fact that your wife noticed the leak, measured it, and described where it might be coming from is a marvel. My wife is still in training. I hope to have her notice things like that and actually care someday.
I hope it's just the plug.

When my wife said the leak was 16 inches in, I was a little worried. My 83 911, which I R&R'd the engine many times myself (10 years ago), had the transmission connected on the front of the engine, with the engine mounted at the very back of the car. I thought I saw a diagram of a Cayman recently that had the trans behind the engine (I think the Caymans are mid-engine cars?), so I briefly worried that the 911's somehow changed their basic drivetrain design since when I was into Porsche's last; and that 16 inches in could have meant that the oil leak was related to the RMS.
But I've come back to my senses now. I'll be climbing underneath her tonight (the C2). Funny, I thought it would have been a while before I was breaking out my old Craftsman floor roller again to slide under my car. Thought those days were behind me. I'll be doing it on day two of ownership. I'm not as flexible as I used to be, but I'll be alright under there.
Relatedly, I used to jack my car up (83 911) by putting a piece of wood on my two ton jack, and placing that under the middle of the engine block. This was the quickest way to jack up the car (i know, some say it would stress the engine and create leaks because that is where the two engine halves came together, but never did). So what is the proper way to jack up the rear of these new fangle-dangle 996's so that I can get me some breathing room??
I didn't jack up my car on my last oil change. I just backed it up to the raised edge of the garage, so the rear of the car hung over the lip. This gave me enough room to get under the car on my back in the driveway.
Damn, I check the seller
efini93fd3s
and he hasn't been selling them lately.... sold them in 4 (OEM (Mahle) filter, washer, and "O"rings).... dont know what happened to him. Sorry.
yea, I looked for anyone with the washers and thought... didnt someone offer the filters and washers before ... well, sorry he isnt selling, I will have to try the next on the list and just buy a washer
haha
Jacking the car Todd....
so what I do is raise the car on one side using the jack points in front of the rear wheel, then when its up high enough to get my floor jack under it I slide it up to the cross member (right where the tranny and engine connect) in the center, and just raise her up... I go up high enough to put stands under the 2 side jacking points and then rest on all 3....
if your car is low, watch the nose as it can come really close to the gound with the butt up so high....
sure others will tell you their way but for sure, do not jack on the motor! The motor mounts wont like it, but the guy selling them will at $400 a pop !
Just roll the car to the edge of the garage lip. The engine will be over the driveway. That will give you the extra 1" to 2" you need to do the oil change.
I am lucky, my yard is flat and a dead end street, all I do is drive onto the grass and back up towards the street until the *** overhangs the curb...I gain about 5 inches - nice and easy. I dont do this for ant other thing than the oil change, even though I dont have but 2 neighbors and they are cool (in fact they stand there and watch me while we drink a beer and watch the oil drain forever) but it still looks a little ghetto
the pan I use has a single hole in the top... the oil comes out fast enough that it doesnt drain into the bottom of the pan fast enough and starts to fill up the upper portion - it does make it without overflowing, but it is a close race!! - scared me the first time
for the filter I didnt buy anything special.... I cut 2 pieces of left over thin wall PVC drain pipe for my downspouts..about 2 inches wide, then removed a section so it was not a ring, but rather a "C" slipped those over the filter housing (one over top of the other) and then a regular oil filter wrench works like a charm. -
