Update 3/11/2018
I've been reconfiguring my shop over the last two weekends and picked up a new addition to family. Stewie was born on 12/31/2018, the same day I got the 911. I picked him up last Saturday.
I did however get time to get one half of the case into the blasting cabinet. If you remember from the previous photos, there was a lot of hard white crystalline/mineral looking corrosion on the outside of the case, almost looks like calcium. That turned out to be where water was seeping onto the engine and reacting with the magnesium over time. I used garnet to blast the case which removed all the white deposits but left the case much lighter, almost like aluminum. This is fine because after about 24 hours the dull grey appearance returned as magnesium reacts with the oxygen in the air.
After blasting. Note the pitting from the corrosion. I also discovered the number 477 on the top of the case. This was completely hidden before.
After 24 hours. Nice and grey again. Ready for case mods.
