First off...the mistake was made during final assembly, we were obviously morons for missing this step. Somehow we didn't realize that the dipstick tube needed to be installed into the engine, not from outside. We didn't realize this until today when we were torqueing down the intake getting ready to fire the engine. Needless to say, I seriously DO NOT WANT TO PULL THIS ENGINE AGAIN, especially at the point its at right now...unless there's no way around it. Is there a fix for this??? I know we can't be the first ones to make this mistake. There has to be an answer for this. Ideas????
