We have a thread being posted to right now showing the lifter and variocam sealing ring failures.
My only advise is to change your engine oil. Don't let it get past 5K miles and keep a eye on your oil filter.
For those that are looking to buy a 2nd hand 996TT, try and view the car prior to the engine oil being changed. View the car with at least 2500 miles on the oil.

Ferrari and Lambo and all the others would "kill" to have a guy post about 300,000 MILES with routine oil changes....no issues...with track use.
These cars are absolute tanks. Period. In the world of super cars, they are in a league of their own. Anyone who wants a reliable car that has high HP should get a 996TT and be done with it. 100$ for a gbox mod, and away. Ferrari maintenance costs seem super scary to me. My audi's...they had a LOT of issues...all 6 of them... Mercedes and BMW have had some doosies of late..the last M3's engine....etc. GTR's....let's give them a few years after the warranties run out and see what happens to them. They might be as reliable once Nissan gets things together...but again, if you track them, the costs are astronomical.
So the PO wants data...it is few and far between. Use of some common sense, as I put forward, will likely reward the end user with hundreds of thousands of miles of fun.
To those buying these cars...they are the bargain of the century. The "new" headlights causes them to upset the old guard of the 911 world. Modern designer types actually usually think the new headlights look better, newer....once the world understands how special these cars are..they will go up in price. Right now, they are probably 40% discounted from what they are worth. No regrets on my part for buying one.
There, I said it.
T2's religion about 0w-40 oil changes is probably all that is needed. Yes, it is a machine and parts break, but at an alarmingly low rate relative to most cars...let alone "supercars." Just change the oil out before the additives wear out and you'll be superb.

I'm not sure they will ever be a true classic, but they are a fantastic car for the money.

Because this forum can't discuss the 996TT engine and their issues here I am not going to participate any further here. I can't contribute to a forum that insists on living in the dark and only insists on listening to one engine builders input without discussing and clearing up the issues. The only way for people to not be paranoid about their cars is to know the facts.....

Haulinkraut, you have started one of the BEST threads I can think of and I encourage you to stay with it. I have this "noise" you are refering to and I need to hear from folks like you so I can learn more and hopefully understand whats going on? I come over from the 997 TT forum along with others searching for some answers as to why when I purchased my car in 2007 the noise did not exist? Why did the noise only become apparent at around 12k miles and became more pronounced as the miles went up? I almost have 30k miles now on my 2007 997 TT and although many have called this noise "normal" I really find it hard to believe that one would have no concerns over it? Thanks to Kevins help I was able to reduce the noise a bit by adding a thicker viscosity oil. This is a description of the noise that I refer to (I have tried to upload sound bytes of it with no success).
1. The noise occurs at idle after the car has warmed up.
2. The noise gets better after 2000 RPM (it literally disappears to a degree)
3. The noise is specific to the GT1 engine (found on Turbos, GT3's, etc)
4. The noise comes directly from the crankshaft itself
5. Pressing the clutch in or out does not change the noise or make it better
6. The metallic sound can be described as marbles churning inside the crankshaft or a chain banging against a metal surface.
This noise I am describing in its mild form (like when it first started) is not really something one would be too concerned about or something that one would obviously notice. However the noise becomes progressivly worse with time and it gets to a point where you feel that it warrants further investigation. Hopefully this thread can provide some answers. Specifically what is going on here?

I think Jeff makes a very valid point. For the number of track days that Porsches do, and the beating they take from it, no other car is engineered to their standard. And T2 tracks his car along with having 300,000 miles on it. Like I said earlier, every machine made is going to have some problems along the way, but Porsches hold up to the most demanding type of service.

Guys if you think this thread is a waste of time why not move on to another one that interests you? Thanks to Kevin and his advice I have reduced this rattle considerably. Had it not been for these discussions I would have continued to use a thinner oil (0W-40) and not help the issue at all. If you do nothing and simply ignore it thats fine too. To each his own.

[QUOTE=raineycd;8481887]lol. In all seriousness, there are some good tips and advise to care for your 996 turbo. I think Kevin and some of the other guys that have the gristly privileged of dissecting failures are the ones who know best. I take their advice seriously and apply it. I am going to enjoy the car and if it fails, it fails, but not due to my lack of attention/diligence!
Well said. I totally agree with you!
