ok guys i just got my motor going about 200 miles ago.and ever since it has had a slow oil leak oround the head .it leaks right where the little part number tag is on the head gasket. the head and block were both machined and should be flat.the vtec silonoid gasket is new,cam plug is new,i even changed the hg and its the same thing.oh yea its a b16a,and i just did a full rebuild all oem parts.any one think the machine shop screwed up and the head or block isnt square.or any ideas would really help this is pissing me off. thanks

 

Sometimes when the block and head are machined the dowel pins can end up being to long.This can hold the head up off the block.

the head and block were both machined .4 thousands is that enough to make the dowls to long?

 

try retorqueing your headstuds.

 

any more ideas

 

I have the same problem, and now it leaks a lil coolant when some boost is thrown in. I bet it's those god damn dowel pins Now I'll have to do a headgasket job again just to flatten them down.

 

how much did you mill your head and or block?

 

The head got flattened when I did the last head gasket job. They stamped how much they took off on the head, but I can't see it now so I'm not sure.

 

i bet its your dist. o-ring

 

ok i went to honda and got a dizzy o ring going to put it on right now,ill let you guys know.
