So after removing the motor, trans rebuilt and xcase chain replaced along with 200+ parts replaced it s all back together. Started it last week and loud tapping seems gone yeah!! But i have an exhaust leak now so couldn t drive it home :-(
Not bad considering the heads were removed and everything was taken apart. I ll keep u guys posted and add pics. So far so good hope it lasts! The oneway oil check valve in the block feeding the heads was the root cause since it was stuck open😄
