Boost Leak Test

Hi All,
Just a quick question, Is it better to do the boost leak test cold or on a warm system?
Cheers

 

Either? Both? Should be sealed under both conditions and temperature dependent leaks could go either way. If you're chasing a problem testing under the conditions where the problem is most severe would make sense.

 

I would do both. If its a major leak you should be able to find it either hot or cold.
