Subaru Legacy does not find where the filter goes

Hello friends, I tell you, I have a subaru legacy year 1993 the one that I am fixing I have enough knowledge to do it but since it is the first legacy that I repair I do not find where the engine oil filter I have searched and I do not find the workshop manual for this car, I found one here in "MDM", but the truth leaves enough to desire, and it does not help much, if I could publish something a little more complete.

A million thanks.
