This fucker just refuses to be resurrected.

Jeff, Paul, Charles and I dropped in the 13B 4port that was rebuilt for the silver Cosmo, and the 5 speed box. Everything went smooth, only real hiccup was the carb needed a little extra love. She fired right up.

Then, about 10 minutes in, she started pushing coolant into the overflow. Used a cooling pressure tester and pumped it up to see what's what.

17 psi held bled down to about 16 psi over an hour.

Removed Leading plugs. Pumped it up to 20 psi. Bled down to about 16 psi in 20 minutes.

Dammit.

I did swap in a good brake master cylinder though, so when it does run, it should also stop.

Sigh.
