[HSSS427]

Got a call this afternoon. After honing the cylinder, he saw a slight imperfection in the side of the cylinder / sleeve. Put soapy water on it and pressurized the water jackets, but still hard to tell. So he bolted the torque plate on the block, flipped it upside down, and filled the cylinder with water. He then pressurized the water jacket and found a hand full of pin holes where air bubbles were coming through - he used the term porosity cracks. Felt under heat of a hot engine the flow would certainly increase.

So, going to re-sleeve that cylinder and bolt it back together. So now I'm wondering what's the chicken and what's the egg in terms of my overall problem. Did the head leak and cause the cylinder sleeve to leak, or other way around, or one not related to the other?

However, as Rhett said, "Frankly I don't give a damn"
