I assisted in their development since day one, my 356 engine has the very first set of Nickies ever built installed into it.

The car has already been repaired by boring to 3.6 and adding x51 oil pan.

Well, I replaced my IMS, RMS, AOS, all for insurance and...I end up with a blown engine due to the cylinder sleeve issue.

With them the parent cylinder material is bored away and replaced with an extrusion of billet aluminum..

Isn't it a plating process to allow the use of aftermarket pistons?
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.

Well, I replaced my IMS, RMS, AOS, all for insurance and...I end up with a blown engine due to the cylinder sleeve issue.
My question, does anyone know if Porsche is helping on any of these motors? If I wanted to pursue any help any suggestion on how to proceed? Contact PCNA? Mine was a remanufactured engine according to my mechanic and it failed at 127,000 miles. It's my understanding that a vendor in Finland did not meet the diameter issue so corrected it with the sleeves, so I hoping maybe if I get the right person one the phone, maybe they will handle on a one on one basis.
The car has already been repaired by boring to 3.6 and adding x51 oil pan. I'm not interested in a suit and still love the car (maybe no so much when I see bill). I just thought it might be worth the effort.
You have a better chance of impregnating a blow up doll and/or Kate Upton than you do of getting any assistance from Porsche on a blown engine in a modded 996 with 127k miles on it.
Regardless of Porsche, if you can cut off the cylinders and install Nickies that's the route I would take. Case halves are damn expensive these days if you can find them....

Do you know when the reman motor went in? The later ones contained the larger non-serviceable IMS.
Hmmmm. Mind posting your engine serial number? A reman factory engine should have "AT" designation as part of the serial number like this:
Not genuine Nickies... With them the parent cylinder material is bored away and replaced with an extrusion of billet aluminum.. Then they are Nikisil plated.
I assisted in their development since day one, my 356 engine has the very first set of Nickies ever built installed into it. Back then all we did were aircooled engines.
Ok, so in simple terms the cylinder is sleeved and then plated, dry sleeved? The original cylinder material is still there to retain structural rigidity to the block.
Not exactly. The only parent material that remains is that below the coolant jackets. To enhance thermal conductivity the entire original cylinder is removed above this point.
The Nickies cylinder is several hundred times stronger than the parent material of the crankcase.
