EJ25 SOHC Crank Pulley and Other Q's

[czm]

Hi all 

New to this Subaru marlarky so hopefully you kind folks can help.

 

I am looking for a replacement crank pulley for my EJ25 Outback engine as the original one is looking worse for wear.

 

Is it possible to get lightweight/aftermarket crank pulleys for the engine?  Of course I have seen loads of options for STis ect bit not for this engine.

 

Another question is as I have stripped down my engine and replaced the Head Gaskets I need a diagram showing all the bretaher hoses ect and where they go.  Does such a diagram exist as I can find one.

 

In particular I am looking for something that shows where the breather pipes from the rocker covers goes and also the block breather (see below)

 

.

Thanks
