Hey guys, thought I would share a video of my first oil change. Hope you find it helpful!

Thanks for sharing! Very helpful for new TT owners....Just a note, turbos drain plugs should be torqued to 22 ft/lb....

Great, thanks for the additional info!

Good job. I hope you will do more DIY videos for the 996TT.

Good job except you left out the replacement of the small "O" ring at the based of the oil filter cap stem.

Good job on the video. More proof that we don't need to pay someone elses husband $200-$300 to change our oil.

funny, I am doing an oil change later this week and watched your video last night...ha ha. you also had trouble pulling the fuel pump fuse

The "996 Turbo DIY thread repository" thread at the top of this 996 Turbo forum has some real nice DIY links.

Is it really necessary to pull the fuel pump fuse?
Doesn't the oil pressure build up a second or two after it's started?
Plus it's a dry sump system, so after filling it with oil, shouldn't it be about the same delay in building pressure as when it's left over night?

I'm going to do my first oil change on it soon and the shop manual makes no mention of pulling the fuse. I feel like there is more harm done by pulling the fuse and running the engine lean as it runs out of fuel, rather then just waiting a second or 2 for full oil pressure.

By the way, nice video. Thanks!

Video is definitely a great DIY tool. Good job.

I was thinking the same thing.
Reading this and other forums, there appears to be 2 schools of thought on this. The "pull the fuse" school and the "no need to pull the fuse" school.
Unfortunately, these appear to be based more on opinion than science.

Does anyone have evidence (other than "I do it with/without pulling the fuse and have never had any trouble") that indicates one method is better than the other?

My thoughts are to go with the "pull the fuse" school. By turning the engine over, but not allowing it to actually run, priming all of the voids in the oil channels and passages that cause the initial low oil pressure is all done with zero load on any of the bearings just feels like it would be better.
But then, that's just my opinion and worth every penny you paid for it

Agreed. Great video -Thanks!

I am waiting for someone to record and post a vid, showing how loud the lifters and valvetrain sound on start up after what I call a DRY start.. Fact, at idle/ start up the turbochargers are tuning around 20,000 RPM's... there is little to ZERO oil pressure for seconds. The spring loaded checkvalves haven't even opened on the turbochargers> due to the lack of pressure. The result is accelerated thrust wear in your turbochargers.. I have seen it.. Bronze metal being transferred on to the steel thrust stack washers.

Why take the risk.. It's night and day difference between a primed engine start vs a non primed start. My only recommendations (to the video) is to prime the engine longer.. 10 seconds or until you see at least 2.5 to 3 bars of oil pressure.

And "no" the start up is not the same vs leaving the car in the garage over night. The oil has been drained, oil siphons out of the galley's and lines. Air fills the void. The oil has to compress and fill the lines and galley's (time)..

Kevin - would this be true (the turbo starting up without oil) if you did not drain the turbo oil? I'm tempted not to bother draining the turbos between the factory recommended intervals since it is such a small amount.

Well I guess that answers my question. I guess pull the fuse it is.

This is a good point. I'm also curious

Kevin

Here is a riddle Tom....

Condition 1 is everytime you start your engine
If you were to remove "a" drain plug from the turbocharger reservoir sump tank, and start your engine > How long will it take in "time=seconds" to see oil streaming out of the sump tank drain hole??

Condition 2 Fresh oil change with no engine prime..
If you were to remove "a" drain plugs from the turbocharger reservoir sump tank, and start the engine right after a fresh oil change (not priming your engine=did not pull fuse) How long will it take to see the brand new engine oil streaming out the drain hole..

Conclusion, in the end, one person might care, the other person does not.. Similar can be said, about hot shut downs when driving these cars.. Those that want to idle the car down for 20, 30 or 45 seconds and those that cant' be bothered with it...

To get to the point, what is the acceptable time in seconds will you wait to see the stream of oil? Or does one care...
