Thats great, but did they report back their findings? What % is the alternator currently charging at? What mill thickness are all four rotors? Compression check of the cooling system for leaks pass the test. Not being difficult, this is the data you paid for with a PPI on the cheap side. Pay more and get the cylinders scoped for boring and drop the oil pan to investigate further the overall health of the motor. You only get one chance to obtain this data before buying. After, and it’s gonna cost $$$ to make right. I did at least know a clutch was needed and got $2500 knocked offf the purchase price because of it and a few other repairs that were needed. Good luck, I do hope it all works out as these are fantastic cars for what they sell for. But they can be a handful to own if ya get a needy one.

The most important things to look at weren't done or requested to be done...I doubt they'll want to go back out to do more PPI inspecting unless it was done by the selling dealership?

Did they even check for over-revs?

mrfeh

Assuming that would show up as a code on the computer, yes they did.

808Bill

No it wouldn't.

Over-rev report is part of the DME dump, wouldn't show up on a simple code scanner. This can be read with PIWIS, Durametric, or other Porsche diagnostic tool. Certain other generic scanners (like the Foxwell, I believe,) can read the DME data as well...

Long story short - it's usually included, and if it wasn't, should be something you can request for free. Ideally it would look like this:

Range 1: XX (some number.)

Range 2: 0


You don't want any Range 2.

If you didn't see the explicit words: "over-rev range 1, range 2" it didn't get checked

Further info from the tech that did the PPI:

No debris in the oil filter.
The air oil separator should be replaced yes it could cause a Check engine light eventually (it wont leave you on the side of the road )
The brakes and tires are in good condition and do not need replacement. 8/32 is basically a brand new tire. They are date coded 2018 ( they are Sumitomo a cheaper tire ) I believe they have been sitting a little bit slight vibration at highway speeds.
The car drives well no issues.
There is no leak from the Rear main seal.

I will ask the dealership if they can give me overrev data. Thanks everybody!

So, any other opinions about the AOS? The tech that did the PPI seems to indicate it's not something that would prevent me from driving the car home.

808Bill

Trust me, you don't want to be on a 1000 mile road trip when it lets go!

Dr_Strangelove

It's not something that would prevent you from driving the car home - however - trust us when we say you don't want to dig your way out of a blown AOS while in the middle of nowhere. If the AOS is already exhibiting signs of failure then it's kind of a no brainer to me...

I personally would be paranoid on the 1000 miles home with a failing aos and original imsb. Wouldn't be fun at all.

That's why I shipped mine home and had imsb, aos and clutch done by my local shop in case I needed to use any warranty on the parts and service.

Hope it works out!

tekkie

the ims on a 99 i wouldn't be to worried, but i to would address the aos, if you get stuck in some hickville little town you could be there for days with Cletus and his wife / sister lol

no offense to anyone named Cletus

mrfeh

The dealership says they will replace the AOS at their expense.

So, that would be taken care of in VA, then I would drive the car home to have the clutch/IMS/DMS done.

Any reason not to proceed?

808Bill

Lol, I think he has to go through West Virginia too> "Deliverance" country!

I see no reason not to, make sure they use Porsche parts and not after market, pay for a plug change too. Get AAA and hit the road!

tekkie

not from my perspective, just make sure they use oem and not some cheap aftermarket one
