oil COnsumption until 1 qt low

Dang..... that is like a qt every 100 miles. Sorry... that's very bad oil use. Something is quite wrong. Can you find that exact SCAT crank kit number?

(The one time I used anything more than that at a new build I messed up the end butt of one oil ring expander; burned a qt in 20 miles! Replaced the ring expander and all was good.)
