Thought i'd share the engine rebuild progress on my XJ400 with you guys.. Apparently the Number 1 Cylinder Rod bearing had spun in the cap, the condition on the other 3 Rod bearings don't look good either hence i'll be replacing all 4 rod bearings, ofcourse after plastigaging em. Another issue with the motor would be the Primary chain, it apparently has stretched beyond it's limit, Would often slap the counterweights when running.
Wish me luck
