in the pic i posted, i got the machine shop to block that hole, this hole is the flame trap breather on a zetec.

i have removed it now, its in the garage but im not gonna be in work tomoz to bother to take a pic and upload if for proof

basically to make it into a decent block breather i will make a plate out of 4mm thick alloy sheet, then get a 90 degree alloy tube welded on to that.

hey presto, a take off for a block breather - is it really that hard to grasp the concept??

ps dojj, its not in the water jacket, with it removed its just a fucking great hole in the block
