I'm wondering if anyone might offer some advice on an issue with my 1999 996 Cab (106k mi). I've been a Porsche owner only since 2004 and I just learned a new word--"intermix"! I took it to Pioneer and they took out the oil cooler (bad), put in a new one and it has not solved the problem. After talking with Mo at Pioner, I concluded that I need to replace the engine or sell it as is. Any thoughts on the wisdom of a replacement imagine at 106K mi? Any advice on how to sell this unit as is? Any charitable contributions???

Thanks to anyone who feels my pain...

This must be one of the early Models with the liner or a cylinder head cracking and letting coolant mix with OIL. Is this what you mean by Intermix?
There were stories of improper casting of some of the heads by Porsche on some of the early engines.

It is not really intermix, it is a broken motor.
Intermix is a cooler failure; which I have never personally seen on a 996, only motor failures.
We have done 2 of these this year alone. (1999 MY)
If you pull the oil pan the coolant just falls out.
This happens from either a head or case casting issue or more frequently a broken cylinder liner upper lip.

You can replace the engine and keep it or sell it (It will have a 2-year warranty which is a nice sales feature) Or you can sell it as is. If you sell it as is you should contact local independent Porsche shops or post it on the classifieds on this site.
You can also talk to the dealer about trading it in on a new model.

Donating is not what it used to be. You will only get what the Non-profit gets for it after they complete the deal. It will be a small figure...

The problem is the engine replacement will cost just short of what the car is worth.

The question is do you want to keep the car or is it time for something new.

You could try to find a used engine, but that is a huge gamble as you could be back in the exact same situation in no time.

Keep in mind that because of oil in the coolant hoses may need replacement. The clutch should also be inspected and replaced if original. Get a comprehensive estimate before you take the plunge.

I would take your car to another shop for a 2nd opinion. A couple of years ago Pioneer diagnosed my son's 2000 Boxster with basically the same problem and said it needed a new engine ($10K +). Well it didn't need the new engine and it has been running fine ever since.
