Complete Engine Overhaul

At just over 205,000 miles it was time for a rebuild. After diving in, I discovered a mouse house, pitted cam lobes, worn out cylinders, and an unusable crankshaft. It was a lot of work but probably one of the most rewarding jobs I've ever taken on.

Resources and Tools

My number one resource was Wayne Dempsey's book: Porsche How to Rebuild and Modify Porsche 911 Engines

I also purchased two specialty tools from Pelican Parts: Porsche Engine Stand Adapter Half-Ring and Porsche P237 Cam Shaft Securing Bar

You will also need to make or buy other tools you may not own such as a dial indicator, valve spring compressor, flywheel lock, and feeler gauges. Wayne's book is great resource for tools and sealants needed to complete the job.

Below are other resources and shops I used:

The complete overhaul was time consuming and tedious at times. As you can see below, a lot of parts needed thorough cleaning. There were a few tricky steps such as cam timing, but Wayne's book does a nice job walking through each step. After completing the rebuild I had to pull the engine out again to replace a broken valve spring. When it was out I decided to also replace all the soft fuel lines, the damper, and the regulator. The engine also has an M&K Pre-Muffler and exhaust and a performance ship from SW Chips (formerly 911Chips).

The engine runs and sounds fantastic! I wish I did a little better job sealing the case. It still weeps a little oil. But overall not bad for rebuilding an aircooled engine in my basement.
