Hey lads,
I am after getting the head gasket done in my 02 zxr, since then it has been leaking a bit of oil so today i took of the flairing and saw that the oil iis leaking from small dilling in the head just under where the exhaust manifold bolts onto the head, there is a drillind under each exhaust port about 5mm diameter. any ideas what this drilling is for or or how its leaking from here?
thanks

the holes you describe are drain holes for the spark plug recess................given that you have just replaced the head gasket I'd guess that you have not correctly fitted the rubber seals are the top of each recess....................I've never had to replace one of these seals that is why I'm guessing that one or more is incorrectly fitted...............they need to be the corrct way up as well........................

There is also a rubber "O" ring at the botom of the little tube that forms the top part of the recess it could also be one of those that is passing oil
