I have checked the normals. Hose's, waterpump, tstat. This leak seems to be under the
intake plenum chamber. It runs down the back of the motor. I am unable to see under
the plenum. Could this be an intake manifold leak or is there a hose or connection that
I don't see in my shop book under the plenum?

Thanks for any and all help

 

Waterpump o-ring probably. Or I read somewhere that there's a weep hole in back but I'm not 100% certain.

 

It will leak down not even running or even hot. Just sitting at rest
