Hey all,

Originally I was looking at buying a boxster to replace my aging '87 944 (god I love that 944). Now i'm planning on getting into a 996 instead. Anyways, I was doing a ton of research about the 986 and know alot about the engine issues that came with them. I know the engines in the 996's are essentially the same as the 986 boxsters (except of course liter size), but I hear alot more about engine failures on the 911's then I do on the boxsters. I was kind of curious as to why since they're very similar. I see alot of boxsters with 150k+ miles, but not so much from 996's. I'm guessing they made many more 996's then boxsters and maybe that's the reason why. I'm looking at buying a high mileage 996 (80k+ miles) so right now i'm trying to educate myself on this model as I did with the boxster. Oh, by the way there is a huge article about the 996 in 911 & porsche world. They prat on and on about the grenading engines which is sort of a shame since I wanted to read a little more about the car. I guess 90% of these engines are terrible from how they were talking about them.

1998 996 C2 - now 101,000 miles!

I'm the fourth owner :)

oil seal @ 21,000

cam seal @ 36,000

new clutch, coolant tank @ 63,000

cam seal @ 68,000 (and a load of other seals, sleeves and rings)

cam seals @ 70,000

seal ring @ 73,000

clutch release @ 76,000

new gearbox @ approx 80,000

Blue Pearl complete respray @ approx 80,000 (previous owner had a girlfriend incident...)

ignition barrel @ 85,000

corroded brake pipes, radiator fan, clutch/slave repair @ 93,000

oil separator @ 93,000

radiator @ 99,000 (pressure test found coolant leak from possible stone damage)

I've left out oil/brakes/suspension/sensors. Of all those seals, one was about 20p and I presume that is RMS? At present mileage, car needs discs and pads all round, and I can feel suspension arms/bushes need attention, and possibly sway bar too as car clunks when I get in and switch on.

Car is now a daily driver :)

Nobody drives the 911s. Lots of people use Boxsters as daily drivers, which results in lots of high-mileage Boxsters. Very few purchase a 911 for that. Those of us who bought the early 996s for use as daily drivers in the past couple of years are just now starting to break 100k miles.

My 1999 C2 is up to 99,380 miles on it. Last time I took it to shop he alerted me to small RMS leak. Going to get that done same time replace original clutch/flywheel soon. Other than that no complaints and runs great! Last year I put 20k miles on the car and only had to change the gas cap to fix CEL, change oil, and replace front brakes. Can't complain about dependability for sure.

2002 C4S with 99,000 kms... running strong.

I am third owner, and first to use as a daily driver.

All original as far as major components that I know of, though RMS was done under first owner warranty.

Needs brakes in a bit.

I plan to do PSS9/10 -- though suspension is actually fine.

Uses one litre of Mobil 1 per 3000 kms -- nothing wrong there -- just a genuine Porsche :)

80,000 miles on my 1999. OAS, two bad radiator fan resistors, window regulator, an occasional seal to stop an oil leak, lots of other little stuff, but no significant repairs. Just found a pinhole leak on my water pump indicating it is time to replace that. When talking about the reliability of these cars - keep in mind your driving style. If you essentially autocross you car everyday driving to work with your hair on fire, 100,000 miles before the engine dies is an incredible run. I had a 1998 M3, and that car just could not take it - after just 60,000 miles, literally every system was or had been obliterated. Given the way I drive, my 996 is holding up like a tank. For those of you who have suffered an expensive engine failure, I feel for you, but your bad luck does not represent the norm for the car. If you fail to inspect and make repairs as necessary on an older vehicle leading to a failure (water pump), that is your fault, not Porsche's.

Because you drive every day with your hair on fire IS likely the reason why your car is holding up like a tank! Cheers.

I hit the 100K mark coming back from the beach Saturday. In the 18 months I've owned (since 83K), no major problems , but I can feel the clutch starting to wear. I will replace that in the next few weeks along with oils and the AOS.

2000MY 996 C2 w/6speed with 85k miles. No issues. I've had it three years, driven it 15k miles, and enjoyed 8 PCA DE track weekends. I'm the 4th owner, but the car was well-maintained and kept reasonably local so long-term records were available during my pre-purchase inspection. That revealed no previous problems and consistent major and minor service intervals at a dealer. One spark plug tube was replaced upon purchase.

Original RMS, clutch and transmission. No leaks or seepage. My 996 gets an annual checkup at the Porsche dealer and, of course, an hour-long inspection by my local independent shop before each DE event. Techs haven't found anything worth commenting on, and they know I want them in the "pre-flight" inspection frame of mind (i.e. looking for reasons not to fly).

No measurable oil use between changes, even given track use. Changed to OEM sport pads this summer and will be installing new OEM rotors this winter (I believe the current ones are original). Saw my first warning light two weeks ago--brake pad wear warning at the track (as I was doing a lot of late-braking :-)

Engine pulls strong and consistently. The car handles well and is a joy to drive, even on long hauls.

Perhaps I'm just lucky, but this has been an incredible car.

Upgrades include:

OEM aero kit

OEM front radiator kit

LN Engineering low temperature thermostat, oil filter adapter and deep sump kit

OEM X51 oil pan & baffle

X74 suspension (on its way for a fall '09 installation; currently have factory US M030)

92,000 miles 2000 C2 manual. Just about to go in for an oil change, transmission fluid change, brake fluid change, pads, discs and braided hoses all round, new throttle cable, shock absorbers all round and a 4 wheel alignment setup. Should be like new when all done :)

1999 C2 Cab. 111000. Water pump and clutch at 104K. Last clutch at 60K. AOS replaced not really needed but during clutch I figured what the hell. Spark plug tubes to get rid of the mosquito fogger effect at 108K. MAF and two oxygen sesnors at 110K. Other than that dead nuts reliable and driven like I stole it daily. Oh original engine. Also, does not burn one drop of oil between 3500 mile oil change intervals. Still using stock fill specs. Never ever had RMS issues or IMS issues. Gonna go drive it like a madman to get some beer right now instead of knock on wood.

Just bought a 1999 996 with 99K miles for a steal. Here's hoping I'm not looking for answers in the dead engine forum next time I sign in! ;)

Well it is really great to hear of the many success stories out there. I am getting ready to try and drop my engine and tranny this winter for an update and some maintenance. I am at 82k now and no major issues still, just run into the dead battery from time to time if I do not drive her for a couple of weeks. Right now I am going to send off the tranny to have the 2nd gear pop out fixed, and the motor will get the accessories updated, pumps, mounts, A/C drier, plugs, and anything else I can think of as well as the Clutch etc.

Good luck to you all and you San Fran remember drive it hard!

2003 C4S

196,984 miles so far. I bought the car as a dealer ex-demo in July 2003 at 3,870 miles. It's had 2 engines & 3 tiptronic gearboxes but still the original supsension (apart from as set of Powerflex bushes)

I just hit 155k on the original engine and transmission.

I am happy for you :D . Good car.

BTW, what is the year and model of your car? Have you ever tracked or raced it?
