Thanks for the update and back filling some of the details. That explains why someone would be trying to sell a car with a cel flashing. And we now know you have some mechanical ability. These are important details.

However, you do need an experienced Porsche mechanic to diagnose the problem. Then you can scour the Internet for the cost & effort to do the repair. There are plenty of forum members who have torn down their engines w/o being a Porsche certified mechanic and lived to tell about the many miles thereafter. Only you can decide if this is something you can tackle.

But if you wait, there might be one that appears needing brakes and a bunch of service that would be better suited for someone to jump into the Porsche world. You don't have to marry the first girl who kisses you.
