i own a escort 1.8 zetec 16v 1996-7.
when i take disconnect the ht leads from the plugs and look through the openings there are two plugs in between the 1st and 2nd spark plug and also between the 3rd and 4th, i presume they are threaded due to the (star) socket needed.
around them is quite a build of rust deposit with what looks like small blow holes in the rust.
I am losing water and can`t find the source could it be that it is ecaping through these or are they plugs for the oil.
thanks in advance ,vinny
