First Generation 996 Engine

[911h20]

There is an October article in 911 & Porsche World that discusses earlier M96 engines and AutoFarm's theory of seal and cylinder failures. Very interesting and contradicts other articles written on the subject RMS failures. Not very flattering for Porsche. The saga continues

What exactly is the definition of 'early?'

Can you summarize their theory for us. I thought the cause was pretty well determined. Would be interested in hearing details. Thanks :)

I will scan the article and post.

I believe 3.4 motors or pre autumn 2000.

There isn't very much information quoted from Autofarm in the article. I don't think this article significantly changes what is known about "RMS" leaks since a "RMS" leak has become a garbage dump term used to describe leaks from more than the RMS in the M96 engine. All this aside, Autofarm seems to be offering there expertise in rebuilding early M96 engines. It was only a matter of time before shops started taking these engines apart. I don't think you'll see this type of service offered for the M96 03 engines until a significant number start coming out of warranty.

It remains to be seen if there solution, which was not revealed in detail, will be durable and cost less than an exchange motor from Porsche. A 3.8L conversion is interesting, but again it has yet to be tested by any of the major publications.

The new liner conversions in the Autofarm rebuilds are made by Perfect Bore. Details at: http://www.perfectbore.com/watercooled.htm . It's a nice idea to go to 3.8 litres, bur when you start adding up the price of the parts it's an expensive exercise.

A supercharger starts making a lot of sense.
