Orient were looking dangerous every time they got the ball in the box. However, Boca pulled a goal back before the break and at half time the game was closer than it should of been.
Orient came out determined to turn their possession into goals in the second half and that's what happened.
Lester got his second of the day and once again Sinclair followed up with his second and Orients fourth.
It was only a matter of time before Green got in on the act and after some brilliant work from Dan Howard on the right to beat his man, Green was left with a simple tap in.
Orient weren't finished there, Lester took a lovely corner and Adam Conway met it at the near post with a great header for number six.
Boca got a goal back against the run of play with a good finish for 6-2 but Orient finished things off with goal number seven which was a well worked goal after some nice play between Perry Kissin and Josh Hambling, Rob Silverman's flick on found Green who beat the defender, rounded the goalkeeper and finished with the outside of his foot.
Loughton manager Dan Curtis told JC Sport: "I was pleased with the result today. We played well at times and created plenty of chances. We now need to take that into the double-headers we have coming up which will be massive."
