Default Re: changing rear main seal on a 223

Find the tool that will allow you to thread a new top seal around without removing the crank. Some instruction say to soak a new seal in oil before installing it. An hour is good, a week is better. That was the seal that still doesnt leak after ten years hard driving and some racing too.
