Hi, this is an update from a post I recently made on a Nikasil liners topic in the 997 forum (http://www.911uk.com/viewtopic.php?t=86763&postdays=0&postorder=asc&start=0)
I am in the process of buying a 2002 996 C2. It previously had a Hartech experimental overbore engine fitted in 2011, this engine failed in 2014 just after the current owner purchased the car (at a premium due to the engine spec) from a specialist in the south of England. The specialist rebuilt the engine under warranty apparently liaising with Hartech and refitting crank cases with new Hartech Nikasil liners and OEM pistons to all 6 cylinders, bringing the engine back to a similar 'enhanced' specification as when it was first advertised and purchased. This is all explained in a detailed letter they wrote to the owner.
The current owner has had the car back for about 6 weeks (done 2k miles) and decided to sell it. I have paid a sizable deposit and taken the car to another porsche specialist for a pre purchase inspection. They have done a Borescope and found severe scoring on cylinder no6, with possible scoring on no5. Also they have told me that the engine does not have Nikasil liners. Hartech have also now seen the Borescope images and confirmed that they are not Nikasil liners.
When asked about this, the specialist then confirmed that there was a mix up and that actually a second hand engine (with new OEM pistons) was fitted which they sourced. They say that at the same time they were doing 3 996 engine rebuilds and there was a mix up over the engines. Also the chassis No has been ground away which they say is standard practice.
Now anyone who knows anything about these engines knows that they are a weak point. One of the best remedies out there is rebuilding them with re machined crank cases utilising new stronger liners. In fact this is now the recognised method of repair for these engines. Hartech practically wrote the book on the process (see their website). Personally I would not buy a 996 that hadn't had this remedial work done.
Myself and the owner have contacted the specialist and discussed the situation. They have offered to repair the car under warranty but to only repair the cylinders that are damaged. This is despite their previous claims (in writing) that they had fitted all 6 cylinders with Hartech liners. We have been told by the specialist that there is an option for additional amount (£2500) to be paid while this work is being done to have all 6 cylinders done but neither the owner or myself feel we should have to pay this.
Bearing in mind that I am not the owner (yet), I want to understand how myself and the current owner stand legally and if there is a legal requirement for the specialist to make this good or pay some compensation? Can anyone help or suggest the best way to get this resolved ?

Yep I'd be more worried over the grinding out of the chassis number :what:
