74Proii: Take a look at this for me please... you might have to zoom in, I marked up the photo...
Looking at the staining- and I’ve only ran the engine for a total of maybe 20 minutes-so it’s minimal- I think the coolant is leaking out the top of the coolant passage and getting sucked back in the intake. 1250 Felpros, proper alignment and torque, but I appear to have a 5 thou runout on the lower intake(with a straightedge I can just fit the 5 thou feeler guage in spots). You’d think the gaskets would take up 5 thou, but I guess not. Have a machine shop plane the intake? Or just replace?
I thought I saw a bit of white smoke when I first started it. Brushed it off though.
Hope everyone is having a good day!
