Turns out there are a few folks that want to see this. This started as a tangent to the "Which Engine is best, 3.2 or 3.6L?" thread. There is a voluntary factory recall on many of the 1995 and 1996 3.6L engine wiring harness' because of a bad formulation in the insulation. It turns into a crusty mess and can cause all kinds of issues.

In my case it was very bad missing when it rained and an increasingly bad idle. But in some cases folks have fried their alternators. If you had/have a new 993 then Porsche would have notified you based on your VIN, but in my case I just bought an engine so was never notified.

Here's the culprit.




Here's what happens at the alternator

Late 70s through early 90s Volvos had this problem, mostly 240s, but many 740s, too. Many 280Zs. MB has stiffed their customers on it, and Volvo, too, but the cars involved took a lot longer to have issues. Even worse is the tranny harness wicking ATF into the TCU on several MB models. Or the electric thermostat leaking and coolant wicking into the ECU on a number of BMW models. Both of the latter are major bucks.
