Have 09 Legacy. How many piston wrist pin access plug are their on a 2009 ej25, and what size allen do I use for reinstalling them?

All EJ25's have four access ports. One is behind the separator plate.

T70 Torx..

Is a T70 Torx the same as a 14mm Allen?

Yep. 

One access port behind the flywheel is held in with some countersunk Phillips head bolts. The best way to get these out is with an impact driver.

An easy way to get the pins out is as follows.

You need a pair of needle nose pliers to remove and reinsert the circlips, a 22mm socket on a ratchet to turn the crank

and  a stiff rod of some sort about 18 to 24 inches long

I only remove the circlip that allows the pins to be pushed out.

You use the rod to snake past the  connecting rod in front of you and tap out the pin from the back of the  rod you're working on.

ie, snaking past 3 to tap 1 out etc.

Use a 3/4" wood dowel as a drift to insert the pin. Leaving the backside circlip in allows you to tap until it seats firmly.
