well i dont have the pics yet but i just helped pull a blown type r. spark plug tips broke off into the engine and did some damage to just the piston tops and the bottom of the head. no damage to the cylinder walls which i thought was a little odd. when we pulled the head the cylinders were filled with oil? i know i dont have the pics up but do you guys think the motor can be rebuilt? i couldnt find any major damage like broken valves or bad scaring on the walls to say its toast. pics when the owner sends them.
