How to do a DIY 991 GT3 Oil Change
#196
I did my own brake flush with Castrol SRF and the Motive PowerBleeder, no harder than any other car such as BMW. I asked my dealer tech if they cycle the ABS during a routine 2-Year brake flush and he told me "no" they don't. They just hook it up to their larger pressure bleeder system that is filled with Porsche DOT 4 brake fluid.
I was told by my dealer to tighten the bleeder screws to 10Nm. I hand tighten lightly and 10Nm is just a little tighter than a "light" hand tightening.

BTW, I’ve sometimes seen a little brake fluid weeping down the calipers at the track in the past with previous cars I’ve owned (also with Brembos) and assumed it was because the bleeders were not tight enough. This is almost never the case. Instead, the small amount of brake fluid that is trapped inside the bleeder can expand and run past the rubber caps if you get it hot enough.
So, I attached a small length of brake bleeder hose to the end of my shop vac with duct tape and suck out the remaining fluid now after torquing the bleeders. Problem solved.

Thanks for the feedback guys. I enjoy doing my own oil changes and I'm glad sharing my experience was useful.
As for the jack stands, Montoya had the link to the site in his post but here it is again:
http://jackpointjackstands.com/
They are made in the USA and very nicely done. The pics below show how they work. The aluminum pin fits through a hole in the replaceable rubber piece which then is placed on top of the pad which has a recessed area to accommodate the pin. The pad comes in different sizes; the low profile version is appropriate for low cars like Porsches.
The pad goes on the jack and the pin is aligned with the hole in the jacking point on the frame. The car is raised high enough to slide the stand under the pad from the back side with the opening in the stand straddling the jack. The pad is then lowered onto the stand and the jack can be removed and used at the next jacking point. Each stand is capacity rated at 4000 lbs so they can be used with much heavier vehicles if desired.
They aren't cheap but neither is my car or my body parts. I really like them.
BTW, for those asking about the jack, it's available on Amazon. It's also a nice piece and comes with a lifetime warranty.

About to do the change on our 991.1 GT3 with the motor replaced last year. Just checked and the oil filter on it now is a OPB.115.351.. I ordered the filter with the part number ending in .90. Does anyone know if the .90 will still fit even though the new filter is a .351? I called Porsche of Charlotte and the only thing they showed in their computer that would fit a 991.1 is the filter ending in .351...Which doesn't make sense to me as everyone here has used the .90 for years, and every website online when ordering the filter shows either the .90 or .91 for the 991.2 years.
Thanks
Thanks

so if your current filter that came off the car ends in .91 the 0PB-115-351 filter should be the same.

Haha I went through this confusion last year when I bought a kit as well. So my g series engine used the .91 on the old filter. The new PN using 0PB-115-351 is the same as the old filter ending .91.

But since I ordered the .90 i'm guessing that it will not work?

Where there are changes only in the last two digits it may indicate a re-stock or an worth upgrade over the previous iteration. When there is a new coding, it is almost certain the new part has been upgraded.
The 3 parts will fit, but given that it is a cheap part, would you risk potentially facing a failure that triggered a part revision?
#206
If it were me I wouldn’t use the .90 and return it for either .91 or 351. If you know for sure that post engine change you had a .90 filter on it go ahead and use it if not then it’s safer to get a filter with the new PN
#207
Working on returning the .90 now to Pelican Parts, even though they won't provide a return label. Picking the .351 filter up from Porsche tomorrow.

Just did the first oil change today! If you jack the drivers side of the car up more then the passenger side, you will get a good bit more oil to come out. Those that use a lift or quik jack's wont have this ability.
I had it flat on wheel ramps first, and once I jacked up drivers side more a lot more started to come out.
Having all of the correct tools, it only took about 30 minutes from start to finish. 20 minutes of that was waiting for the oil to drain.

Oil change done yesterday and replaced my coil packs just for good measure. Ready for May track days!
