6v92 airbox pressure test

[Messi]

Looking to check airbox pressure. Is there a good port to do so? I don’t see any likely places. Thanks

Tap on the air box drains before the check valves.

Thanks to everyone for all the help. I have a lot of engine experience, but know nothing about 2stroke diesels. Now that I own a set, I appreciate answers to all my stupid questions while I get up the learning curve
