Before you drop all that cash on a new motor. I would give Jake Raby a call at Flat 6 innovations . he is well known for addressing the m96 faults. you can get a much better built motor with all the known issues addressed , it will have better performance as well and you also get a warranty. since your in Florida and he is in Georgia this could work well for you. I highly recommend you give him a call and get some info.

 

I got my 3.4 from ladismantlers for 6400 shipped no core charge. 30k on the clock.

 

you should also talk to Seth here in jacksonville - he does awesome work and comes highly recommended.

I am sure many of the sponsors in this forum can rebuild it as well. If the shop is equipped and there are competent and nice (like sponsors in general are) there is no reason not do ask them. They do promote other items and they are courteous trying not to be too pushy. I did not grasp this when I did my rebuild as I was new in the forums. I am very happy with my current Indy but nevertheless, after a while you realize that the resources are right here.

 

Dave,
Take a few minutes and log the failure with, NHTSA

This is exactly the same story I had with my first Porsche. It was a 1972 911S....in 1975. I have driven 9 more cars since then, and the most major failure I had was a blown turbo on a 944turbo.
sorry to hear the same thing happened to you. I relate this only because in the long run, it is a very rare event - supposedly.

good luck with the fix.

one word of advice; when you finally get it back. drive it hard. it was made for that! and over 5K rpm, it is really a different beast.

good luck!!

I'm curious what upgrades are done to the new replacement engines to
avoid having the same problem. Does the new engine have the same 300 bhp?

 

Yes it has the same HP. I replaced mine 04/2008 at 54K miles. Major amount of oil getting into the coolant but not the other way around. Then the price was $8,200 from dealer plus labor to install at LMN. My new motor had a date stamp on the case 2004 so it appeared to be brand new with headers and everything. Upgrades were supposed to have been made to the M96 engine. In my area, Lutzo with LMN Motorsports just recently paid Checkered Flag Porsche $16,800 for a new crate motor with core exchange for another customer who had a cracked case. I should have bought 2 three years ago but who knew the prices would double?

 

My 3.6 in my '02 went in July and my research turned up Jake Raby is the only guy in the entire country when it comes to the M96 engine. Search here and on Google for every name you come across and you'll find the same thing. The only two options that made sense to me were send it to Jake in GA and wait a few months, or buy the remannufactuted engine from Porsche. Either option costs around $20,000 installed and both have draw-backs. Sending my car from CA to GA and waiting two or three months was tough, but I could get a larger displace and more power. Buying the crate motor from Porsche with a warranty sounded good, but I could only get extacly what was currently in the car.
I'm leaning toward the crate motor from Porsche and have the LN Engineering IMS retrofit installed along with the Torque Solutions engine mounts.

 

link?

 

mine really started making like a valve noise, so I stopped !i drop the engine and find out that the IMS feel and look good! but I have golden Flakes in the filter!
and a pinking noise!? What else can it be?
is it hard to strip the engine? Do I need many special tools?
If you can Help I much appreciate

 

You should cut the filter open to see all the metal. Drag a magnet over the metal flakes to see if they are iron based.

Yes you need many special tools & it is very difficult, especially to assemble.

Post a picture of the cut filter with a measurement of the size & we can help estimate the cause. Don't restart the engine as this will cause more damage!

 

Thanks for the reply the particles are not magnetic
and circa half mil limiter on size!
the engine at the moment is on the floor as I checked the IMS and is good!
feels solid with no play !,Oil Pumps ? or rod bearings?
could this be ? If yes I really need to open the core! I hoped not but, truth is if is not the IMS then must be something inside?,
Any one who do reasonable price and a good Job on Core swaps? or how long to rebuild!

thanks again for reply much appreciated
Ciao

 

What year is your 996? Next you should drain the oil into a clean pan to see what else is in the oil. Then remove the oil pan cover & see what is in there. Post pictures. Pan is easy to remove but you need to carefully pry it from the engine.

 

madness , how many miles on your 996? just curious, sorry to hear about the engine
