Wheres my o2 sensor and PCV valve?

[Jutboy]

Hello everyone...my 1985 244GL has failed emissions and sometimes loses its power/acceleration.

I bought a new PCV valve (with the flame trap) and a o2 sensor online and I can't find for the the life of me where they go.

I own the Bently service manual its useless on this problem.

The PCV valve I'm clueless and I assumed the o2 sensor was after the catalytic convertor but I don't see any wire there at all.

Please Help - I appreciate it soooo much - Justin
