I wanted to know how the pistons and cylinders looked after three years operation in saltwater, after using eleven dollar synthetic all that time.<br /><br />I removed the head on one bank. <br /><br />The two cyl's walls looked perfect, no vertical scuff lines at all, and the crosshatch lines clearly visible.<br /><br />The piston heads had about .030 carbon build up.<br /><br />The inside water walls looked very clean and free of buildup.<br /><br />The only negative was very small corrosion pits near the outer edge of the surface of the aluminum cyl. wall.<br /><br />I don't know if bothering with the other side will do anything to slow down the corrosion.<br /><br />Questions:<br /><br />Do I bother with the other side?<br /><br />Is there a best brand replacement gasket?<br /><br />Thanks
