Pentosin dripping after clutch replacement

Hi
I have replaced clutch, DMF and more.
After lifting the gearbox up to horisontal pentosin dripped out of the hole between gearbox and motor.
Everything was 100% dry before installation.

I can only Imagine that it is from the slave cylinder. Therefor i checked the level. It was full / a bit overfilled.
I also put the battery back on and made a few shifts. It did not provoke more spilling.

What do you think?

Thanks in advance guys.

Is it blue? Coolant? No clue how it could get in there though.

There is a coolant crossover line at the rear of each head that goes to the heater core. Likely either a decayed / frayed rubber hose, bad Oetiker clamp on it, or leaking where the crossover pipe joins the heads.

This is after 24hours.
The coolant was lying inside the clutchhousing.

The piping over the flywheel seems 100% dry.

That's for sure coolant. Try sticking a paper towel one ply thick above the bell housing and see where drops land.

Just had look again tonight. I can absolutely not find any wet spots anywhere but the place where the drop is hanging..
In the holes on the picture there are 4 torx that I was able to tighten a bit using a hand screwdriwer (torx).
IT does not make sense :-(
