Smoke from ZF Inspection Window during Engine Break-In

Yet another rookie question.  This has been the most challenging project yet.

I started to break in my flat tappet cam in the new engine today and after about 1 minute I heard a pop and then gray smoke pouring out of the ZF inspection window.

The strange thing is it didn't smell like clutch or even make any more sound after the smoke.  I turned the car off immediately.

Smoke poured out of the inspection window for at least 2 minutes but didn't have much of an oder.

Here are the caveats.

1. I noticed the car wouldn't run once the key switch was let go from the run position.  I figured this was a wiring issue so I hotwired the + of my MSD Blaster coil to the battery so I could continue with the break in.  This + of the coil also goes to the right post of the starter solenoid.  **So, I'm thinking the starter may have been running the entire time and maybe smoke was from there?**  The power master starter still works but seems like the bearing maybe bad and has a similar smell to the smoke.

2.  I didn't install the clutch slave cylinder since the tranny was in neutral.  The smoke didn't smell like clutch at all and the throw-out bearing wasn't noisy, so I don't believe the issue is with the clutch.

Any ideas?  I'm planning to put the original starter in it tomorrow and try again.

Thanks,

John
