I have to add a number of years to a date field. The years come from
another field in the table.
I know I can do this:
select (ii_purchased + interval '3 year') as date from inventory_item;
But I need to replace the 3 in 3 years with another field from the
same table ii_expected_life but I can't seem to do that without
getting syntax errors

Assuming that the field is an int, multiply the value in your years
column by a 1-year interval:
select ii_purchased + your_interval_field * '1 year'::date as date from
inventory_item;
