L134 Coolant in Oil/Exhaust

[bmorgil]

Larry has the key bit of analysis. If that is pitted up then it is going to have to go to the next oversize bore. However if it is not pitted, it is possible it could be cleaned up with a ball hone. I am surprised at the compression you had in that hole especially with a cold engine. I would say it is probable there was enough water and antifreeze to seal it up for the compression test. I am thinking it looks pretty bad. Why not go all the way. You can rest assured then that the motor is fresh when you go out to play! The machine shop will be able to tell you if they can clean up those bores or not. You know its a good core. It was barely running for you. So you know the majior components should all rebuild nicely without surprises. On most cores, you never know what you will find.
