Burning coolant at startup.

Probably a bad coolant seal. We know how FDs and RX-8s tend to run hotter than previous models due to their smaller capacity cooling systems and higher power levels. I tore down four FC engines recently and every one of them had that nasty block sealer crap inside the water jacket.

I'm with you. I recommend a new engine instead of any type of block sealer. I'm sure kentetsu will recommend block sealer, but he's never tried a to do a rebuild and seen the aftermath and/or had to clean it out.
