Performance Engine Rebuild by Me

Winter / 2014~5

My Axis/RAW performance engines worked fine up to 20K miles or so.... at that mileage they would eat oil at a rate of 1~2 QT per 1000 miles. Even when new, these engines would consume a lot of oil.. I believe this was due to the big PTW and ring clearances (knowledge base at the time was to run big clearances).


These days, I am running E85 and considering the current knowledgebase and Cosworth Piston Construction/Material I decided to build an engine designed to run on E85.


I tightened up the PTW and ring end gap with this build... it does not burn any oil between my 1600 mile oil changes.
