Reciprocal links between blogs

Recently I have created links between my two blogs , so site1.blogspot.com
linked to site2.blogspot.com and vice versa.
The sites didn't dissapear from G SEO but no new posts were indexed.
As soon as I withdraw one reciprocal link posts were indexed again and started to appear in SEO.
The blogs had no other of a few inlinks , so maybe when they get more links
that situation will not be considered as 'wrong' by G.
That will be tested soon , so far I will think about three way linking and webrings.
