Well the 3.6 has a new problem that we have not seen in previous 911s. We have 2 3.6 engines M64/01 and M64/50 in the shop right now. The 5 step in house process we used to identify these cracks is Zyglo.
Step 1: cleaning
Step 2: apply penetrant
Step 3: remove penetrant
Step 4: apply developer (in this case dry developer)
Step 5: inspect with black light
Here are the results.
TWO THOUGHTS :
1) I HATE 3.6 ENGINES
2) SHUFFLE PIN 3.6 CASES FOR RACING
