Used Curil K2 for the case halves, after 24h in my (cold) garage it has not become much harder, how lng will it take and how longm miust one wait before starting the engine up?

It doesn't cure hard

Temperature stability: -40°C to +200°C.
In engine maintenance many sealed joints are required above
all to be easily separable or disassembled. Curil K2 meets this
requirement: it does not cure. Curil K2’s low viscosity makes it
ideal for sealing finely finished and superfinished components
whose prescribed tolerances are not allowed to be changed.
Joints sealed with Curil K2 remain leak proof under mechanical,
chemical and thermal loads and yet are still easy to separate.
These special advantages mean that Curil K2 can be used for
joints between identical or different metals, threaded seals,
etc. Curil K2 is resistant to mineral oils (also with additives),
greases, hot and cold water, seawater, gases and air.
Application
Clean and degrease the sealing surfaces. Apply Curil K2 and
leave for 5 – 10 minutes before fitting the parts together.
Processing temperature: +5°C to +30°C.

Their other product Curil does cure ...

It won't; that's the beauty of the stuff. It's a non-hardening sealant. Therefore it won't set-up (like an RTV does) and block oil passages like other sealants can if picked-up by the pump.

GREAT stuff!!

Thanks guys for the info! Starting to get how it works now...

Could i assemble an engine and start it the same day or do de K2 have to settle for some time?

Bolt it together and run with it. No need to let it " set up "
