Hi KiwiGF
I tend to agree - As far as I can see the oil system is in A1 condition, but I have not yet taken the oil pump apart - it feels fine though when I turn it. Hence my suspicion about the end plug leaking and loosing pressure
The drive side big end is showing slight signs - it could just be the result of debris from t'other though - I will post some pictures later, but now need to go to work to earn the repair tokens
The top end work is needed since the broken con rod a) caused a cracked barrel skirt and b) rammed the piston into the head
As the valves tried to open against the piston crown, it dramatically bent the push rods, I have yet to see if the valves are distorted in any way - I am mentally preparing for the worst, but can't bear to look yet
But it WILL run again
