A melancholy moment for sure

, they overlooked this on original rebuild hi when it had thrown a valve on cylinder 1 they replaced the piston and head and had low oil pressure on start up they replaced the oil pumps and it still had the same problem, I open it up and walla, I was hoping they'd missed an o ring BUT its like they forgot to put the piston rings on..... I will be replacing the big end shells sleeves and new rings that should seal the deal
