A few weeks ago I did oil and filter change on my 82 SC and also planned to check the valves. I started to remove the exhaust covers first. When I removed the right cover, something fell on the floor. It was a piece of a head stud.
Further investigation showed a few more.

OK, here we go. A few hours later the engine was on the ground.
I admire your willingness and ability to just jump in and get it done without the usual drama. It's such a Godsend to have the skill, know-how, and equipment to pull a car apart so efficiently. Hoping you share the repair process in due course! Timeserts and Raceware studs?
The first Porsche I ever test drove to possibly buy was an 83 911SC -- it was a grey market Euro-spec car with higher compression and a performance chip. It felt great and I was ready to buy it, but the PPI revealed several pulled studs. You'd never know it driving the car -- it really pulled hard. I ended up getting a 3.2 Carrera at the time, in part because I was spoiled by the power of that SC. I briefly considered having the studs repaired but i was in no position to do that work myself at the time and paying a shop (Bob Grigsby) made the car too expensive overall for what it was -- and Bob pointed out the compression and tune would never be happy with our CA gas.

That's a nice tool you have for drilling out the studs! I've made jigs to assist with similar jobs. I assume you bought that one somewhere?
It's shocking how many problems you are finding. Good thing you tore down when you did! Great work!
Carmagic's posts are always a treat --love watching this kind of work progress! (Thank you for sharing!) That drill jig appears to be Stomski Racing -- they make a number of super job-specific tools. If memory serves I used their piston pin clip tool on the 944. The Stomski tool overcomes the problem of only having one other hole to use for alignment. On most heads, you can use a near by port to get everything lined up. Once the 911 motor is apart, there's no such luck...
I dropped off some items at the machine shop. The Heads, rockers and rods for new bushings, and the crankshaft for micro polishing. The cams are sent out for grinding to 964 profile. I got a new set of P/C 98mm Mahle, so I'm going to shorts stroke 3.2.
Most other parts are inspected and cleaned.
Here a few:
Oil pump was found in good condition, just inspect, clean, assemble.
Intermediate shaft.
I removed the plugs from the crank case and cam housing to clean and flush the oil channels, and made new pieces.
Really amazing work. In the last picture are the parts Zinc plated? If so are you doing that yourself?
In general are you bead blasting the parts to get them so clean? Vapor blasting?
I want to tear an engine down this summer to do a cam swap, I don't plan to be Dr. Detail like you however would like to do a little cleanup of the parts.
