    787 Rotary Valve Seal?

    I have oil shooting out both pistons when starting with the plugs out. I've narrowed it down to the inner crank seals and the rotary valve seal. How do I fix these/find them?

    you don't....you replace the crank, unless you are an experienced machinist in which case it will be possible to replace the seals

    as a hail mary, loop the oil injection line to the RV, put a few oz of tranny seal fix in there and run premix for a few tanks..might work..might not, but the crank needs to be rebuilt
