Does the engine breather system have a drain hole? If so has any one a picture of the location. 3.8 1962 Thanks

Hello, do you have a name? Please add it, it’s more polite to answer that way.

The pipe from the engine to the carb air box has a small hole on the under side, though it can easily get blocked. If you clean the pipe and run your finger nail along the under side you’ll find it.
Also, searching for “breather” can give you lots of answers, too.

Hi Geoff, thanks for the info. I bought a new breather pipe but didn't notice the hole. I will take it off and try to find it. I have searched breather but mostly about the routing of the pipe.
