997.1 GT3 Oil Change
Hello Rennlisters!
I completed a 997.1 GT3 oil change over the weekend and I thought I would share a DIY that I put together. I know there are some others out there but I wanted to have a DIY that I could print out and bring with me in the garage.
I did a couple things different than what the service manual said that includes:
1.) Continue to drain the oil after taking out oil filter.
2.) Putting in 1 qt of oil into oil filter housing to prevent dry start up.
3.) Using channel locks to take off housing, which was a big mistake. Go out and buy the 75mm 14 flute oil filter wrench and learn from my mistake.
4.) Bumping the engine over a couple times to circulate the oil. I'm sure there is a better option, like pulling a fuse or relay, but I don't know which to pull.
This is my first DIY and I wanted to contribute back from all the information and knowledge from you guys. So thank you!
Cheers,

Not sure how bumping the throttle moves oil through the engine without the engine being on.
a) It's fly by wire. With car off, the gas pedal does nothing.
b) Even if it wasn't fly by wire, moving the throttle on an unstarted engine does nothing to the oil.
Otherwise, nice.

Thanks. Hopefully this will help out somebody in the future.
I was referring to "bumping" as turning the engine over for 1/2 sec then turning it off with the key.
No throttle input is necessary...maybe bumping is too close of a word as blipping but I completely agree with your statements about the throttle / fly by wire.
I wanted to crank the engine to circulate the oil BUT not start the engine.
It might be overkill to prevent dry start up, but can't see it hurting.
Do you know the best way to do this?

Awesome. I have to look it up every time - this way I just print it and put in the garage.
I changed the oil in the C4S today, but the GT3 is always a little different. Thank you.

Great tips, thanks.
I usually let mine drain for at least 2 hrs. Once I let it drain over-night; probably a 1/8th -1/4 qt. came out! Amazing how much oil accumulates a drop at a time. I'm sure you do this, but while draining the oil with the filter removed also be sure to open the fill cap. This does help vent the case allowing more oil to drain or at least drain more quickly. A turkey baster works great for sucking up that old filter oil. My wife was a little upset when she yelled for the baster and it was in the garage. Oops!
I always "bump" the ignition several times (8-10) before holding it log enough the fire the beast up. It does lessen the dry start some. I also allow time between each couple "bumps" so not to abuse the starter, etc. That may be overkill but also can't hurt.
9.5 qts. exactly each time with a prolonged drain, as above, on my .2 GT3.
Imagine how much oil is left in there when the service tech rushes through it.
I have added some oil to the filter cavity, but have to ask will that take a qt.?
Thanks again, great tech stuff.

shouldn't the first thing be to remove the oil filter and unscrewing the fill cap?
it turns 3 steps into 2....
1. release fill cap
2. remove oil filter
3. open drain plugs (drain)
4. close drain plugs
5. fill oil filter housing w/ first Liter/Quart of oil (add filter and close)
6. add remaining oil
...also if you have a 9 Liter service fill and you get ~9 liters out - i don't think it's worth it to let it drain any more, doesn't the engine have an 11 Liter dry fill?

I never filled the oil filter housing.. I think I will do that going forward..
Hopefully I haven't done much damage to the engine... (never seen that done at the shop either..) But understand that we want to do the best we could.. !

you haven't damaged the engine not doing this. if given the choice I'd go this route but not doing it won't hurt anything.

I know its overkill, but it can't hurt.
