Before I start taking stuff apart on the old 2qm, I have several questions:

Looks like I have a leak from zinc tube/holder(The thing that zinc screws into) This is the zinc on front of engine. Will someone describe the construction of this piece? Is it threaded into engine block? It appears that there is some type of stuffing involved between this tube and engine block? Is it possible to get a leak from here or am I missing something else?


Thanks for any input.
