that engine has never been rebuilt Look at the block if it has it has 248K miles on it....The block is nasty very nasty like 248k miles on nasty....I am not trying to say anything bad but if you say this engine was recent rebuild an it looks like that sorry dude....Just because you install a timing belt an waterpump that isnt rebuilding the engine....If you rebuilt it have you ever heard of a Preasure washer or Hot tank? It doesnt even look like the tranny has be seperated from the engine in a long time
