The intermediate shaft bearing with 30,000 miles will need to be replaced unless it's the LN Engineering IMS Solution.

When the IMS was replaced, it was with the dual row bearing of LN Engineering.

Looks like it happened recently, based on how clean the sump plate is.

I also had it inspected by the guy who patented �don�t buy a lemon.� He had no reservations about recommending purchasing.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi all. Hoping to become owner of 1999 996. This one has some residue at the bottom of engine. Rubbed off on my finger, but no drips on floor or ground. IMS done 30k ago, but no records of RMS. Driving it, the ride felt good, nice and tight, but clutch felt pretty tight, to me at least. I started it 3 different times and every time it was a slow turnover before it fired up. Owner said battery is new. Owner agreed to vehicle inspection, but I wanted to get some opinions.
Honestly it is really going to depend on the inspection you are getting. Seems like the RMS should have been done with the IMS unless it went bad. The air oil separator is another issue that happens with these cars and can cause a leak although I am not sure if it would leak to the location in this picture or not. Someone correct me if I am wrong but the AOS is on the driver side rear of the engine.
Thank you for quick reply. He has records of AOS being changed as well. The vehicle is going to a 5 star reputable Porsche Audi mechanic for inspection.
AOS are pretty notorious for being unreliable, if it was done in the past few years it could very luckily have gone again. That being said the inspection will turn up what it is.
That seems like a lot of goop on the engine. I would make sure the PPI dude concentrates a reasonable amount of time determining where that is coming from. One would think that if it was there prior to the last work done the mech. would have cleaned that off...
First time I've heard the Taco called a "folded magazine"... Geeezzzzz, what's the guy a librarian or something? I'd be wary of the new sump plate... What happened to the original one? Any surrounding damage to the sump? Welds? Certainly not a total dis-qualifier, but I'd have to hear the story ( "I took the motor apart and... lost the sump plate" ..."my dog ate it"..."someone stole it"... It's a nice looking car otherwise - I wonder what it will sell for?
I wouldn't let oily residue stop you from purchasing it. However, if there is a notable leak, then that's a different story. The intermediate shaft bearing with 30,000 miles will need to be replaced unless it's the LN Engineering IMS Solution. Do you want type of bearing they put in the car?
Overall, you can get a good sense of how the car was taking care of just by looking at the appearance inside and out, and of course, if they had good service records on the car. The best advice is to not skimp on the Pre Purchase Inspection. Even if it passes with flying colors, be prepared to dump $5,000 in preventive maintenance. Good luck!
My '99 had a similar but less voluminous leak from what I'd call the passenger-bank valve cover on anything that isn't an M96 - my memory has abandoned me.
Can you give us an update of the purchase process? Also, for the slow turnover, possibly the replacement of the spark plugs and coils would help. I did on my car, but not so dramatically.
Yes, I saw that, but at what year is what I'd like to know.
We see a lot of cars for sale when ever it's time for a costly repair with hopes of unloading it to an unsuspecting buyer.
Here you go guys. The previous owner gave me all the records when I purchased the car. I also had it inspected by the guy who patented �don�t buy a lemon.� He had no reservations about recommending purchasing. The LN dual row has a 75k warranty.
Oh, and Ratchet. As far as the car turning over, the mechanic who did inspection said it was normal. It was probably something I am not used to since this is my first Porsche. He said clutch is a little stiff due to pressure plate, but has plenty of life. He told me to drive it until needs to be addressed and when it�s due, take care of the IMS as well.
