Porsche 911 CIS Clean Up
After tearing down the rest of the CIS, there was plenty of clean up work to do before figuring out what needed replacement.

Once we tore down the system we knew we were in for a ton of elbow grease. Fortunately we already have lots of experience cleaning up disgusting greasy car parts.
Parts Cleaning
Batches of small mechanical parts like these injectors…
…went straight into the ultrasonic cleaner.
Meanwhile, my Quality Assurance Department decided to conduct a surprise audit. Fortunately she said my engine work was acceptable. ::whew:: 🙂
Bigger parts like hoses, hard lines, etc. were sprayed with Purple Power degreaser, scrubbed, and rinsed with water.
Anything with electrical connectors or vacuum cans that I suspected could be damaged by water was carefully wiped clean or sparingly sprayed with carb cleaner.
After several hours of ultrasonic cleaning and elbow grease, we eventually started running out of dirty parts.
Amazing what a continuous protective layer of leaking engine oil will do to preserve the finish on metal parts. No, nothing was refinished or replated.
Fuel Distributor and Warm Up Regulator Rebuild
If you are expecting a full rebuild of the fuel distributor and warm up regulators, I am sorry to disappoint you. I sent those out because I did not find enough information to convince me to rebuild and set them up myself on this fresh engine rebuild. I did find a few people who rebuilt their own fuel distributors and warm up regulators but they looked incredibly complicated and I didn’t have any idea how to set them up for my car. I decided to farm these out to a gentleman named Tony Donato who is well known on the Pelican Forums for his CIS work. I highly recommend him.
So off they went looking like this…
…and returning like this. Both fully rebuilt and calibrated.
I have a spare CIS assembly that landed in my lap a while back that I may experiment with, but for now these two components are rebuilt and ready to bolt-on.
This means we have officially run out of dirty engine parts. I think. I hope.
Next time Ill cover the evaluation and testing of all these CIS subcomponents.
