Last week I found a 01 996TT in my area with 35k miles for sale at a non-P dealership for $52k, I test drove the car the same day I saw it and brought my 996 C2 to trade it in, they appraised my car and we arranged everything for me to buy the TT. I drove the TT for the whole day before buying it (the dealer let me take it home for a whole day) I was kinda wishing everything was ok, the car looked great and felt great.. but I knew that I HAD to do the damn PPI, $250 and 4 hours later I get a call from my P-dealer.. bad news.... 49356 Type 1 and 4988 Type 2 overrevs, leaks all over the place, front diff was pretty much hanging from the axle and it was dry.. it had leaked all the fliud.. the engine was modified and some wires were fixed with duct tape!, the 30k service was never performed, the oil looked like mud.. the total amount of work the car needed was $20-25k assuming the engine internals were ok... I mean the list was soo long.... I had to run away from the car, I was sad but happy at the same time...lesson of the story: ALWAYS GET A PPI!!

That's the best $250 spent in your case to prevent a 'major' dissapointment down the road. Smart move on your part. It's so easy to fall in love with a pcar, especially a turbo, and then overlook some of its faults just to find out it was a bad car to own. You need to pat yourself on the back, you just avoided a huge mistake by having a PPI.

Type 1s only means that it bumped off the rev-limiter....No big deal. BUT 4988 ignitions in the Type 2 range IMHO would be cause for alarm. I wouldn't want to *inherit* a car that has seen 11-12K RPMS (money shift?)....
Great post, and an all-important reminder to P-Car enthusiasts..

Almost 50,000 times hitting the rev limiter, sounds like the original owner was just a plain idiot. ![nono](https://rennlist.com/forums/graemlins/nono.gif)
Thousands of times hitting a Type 2 clearly indicates an idiot with more money than sense.

I once came across a 13K example of a 1992 911 America Roadster (turbo look Cab) owned by Eddie Murphy. Let's just say the car was trashed and had been bottomed out numerous times. Lucky for him, that 964 did not have the computer "memories" of today...

Nice catch - money well spent on the PPI
Sounds like an abused car - make sure you inform the non-P dealership in writing, so that they are forced to disclose this known information to a future buyer

Sounds like you are indeed wrong...The "counts" are the number of ignitions. There are 3 ignitions per rev....so at 7000 rpm you get 350 ignitions/sec. 50000 counts would be 143 seconds in over-rev (type I) condition. 4988 would be 14 seconds...of type II....I would run still.

No worries. I purchased the Durametric Scan Tool ($250) to read ECUs when looking to buy my 996 GT3. It was surprising to see how many of those "used" cars with low miles had Type IIs. It was more surprising to the sale people who would see me pull out my laptop and plug it into the port near the driver's footwell. Most did not approve of such tactics, but it saved me the cost of a PPI as my "first pass" assessment....

the dealer called me back and they still want to sell me the car, the said $49k.. so 50.000 type 1 and 5000 type 2 are definitely a very large number?

Forgive my ignorance, but if the rev limiter cuts off fuel and spark, causing the revs to "bounce" down from the limit, how do you get a type 2 overrev? Just from going so fast into the limiter that it goes way over??
