Does anyone know if coolant leaking up through the hole when a head bolt is removed from a AJ16 ior AJ6 is normal?
I decided to replace the valve stem seals, and when I pulled out the first head bolt, coolant came out.
I know the service manual said to drain the coolant, but I thought since I didn’t want to pull the head off that I wouldn’t need to. Of course now I have drained it.
FWIW, I think it is a poor design that puts the head bolts through the Cam Shaft Bearing Caps.
