Porsche 997 Engine Rebuild Project

Reassembly is underway on our customer’s Porsche 997 engine rebuild project. This Porsche is owned by a true enthusiast, who thoroughly enjoys driving his 997 cabrio every day that he can.  With just under 75,000 miles on the odometer, his engine had begun to lose oil pressure upon warmup. Our diagnosis revealed a worn rear main seal, and some evidence of moderate cylinder wall scoring. Considering the mileage on the engine, combined with his plans to drive the car extensively for many more years, he opted for not just a complete rebuild, but also having the engine bored out to a 4.0 liter with all new pistons and an IMS solution to ensure trouble-free revving down the road!

This is a fun and interesting project for us, and we can hardly wait until we hear this beast fired up for the first time.

Here you can see several pictures of Brandon, our water-cooled Porsche tech, working on preparation, lubrication, assembly & torqueing of fasteners.

We are also using our new engine building room in order to keep projects running more efficiently and keeping assembly areas meticulously clean.

We will be updating the blog as work progresses, so check back often!
