I just finished cleaning my engine block. It’a barn find so all the coolant ducts were clogged, now it’s looking better. But … I can see significant corrosion around coolant passages to cyl head.
It’s my first engine work, and unsure whether this condition is satisfactory at least ?
One more unwelcome surpise is that pistons removed (& cleaned) are +0.030 by ACL, so I lack further boring option.
