I had put the compressor aside while putting in new transmission.

Recharged and found leak from the aluminum pipe block assembly connection to compressor.

Tightened the 13mm bolt and recharged but still leaks.

Is there an o ring or something in that connection block?

Would that be the cause?

There are typically o-rings where the piping meets the compressor. A kit like this will help:

Yes there is a o-ring and +- 25 mm diameter if I remember correctly. Search the forum and you will find all the sizes to all the connections. Back in the day when i did mine eeuroparts had a great diagram with all the parts on their site. Also try the magical Nylog Blue sealant.
