Core plug leaking

Good morning,

Tough question.

There are 3 core plugs on the block. There are plugs in the cylinder head at the front and back as well as by where the exhaust manifold bolts to the head. There is also one behind the block between the engine and transmission that would require removal of the transmission to access.

If you have one leaking, it is recommended to replace all of them as the cooling system has rotted them from the inside from rust in the system.

This is a labor-intensive job.
