water leak

Its just a little maybe a paint or quart after you drive it a lot like 50 miles. Its not on my dipstick, just on the front pass. side breather. It was doing the same thing and I pulled the intake and it looked like it was leaking on the front water passage pass. side. I have about 30000 miles on it. As far as the machine work he did bore it 40 th, did a good valve job,balanced it and the rest it takes to do a stroker. been running great then this happened. and yes iam running anti freeze. this is my daily driver. Of course I am retired so its not like going to work dsily driver.
