At the moment the centre 2 cylinders on our TSIO360's are running hottest. However, despite our baffles LOOKING good, you can see an airflow pattern and location of 2 leaks on the inside of the cowl. These can be traced to 2 issues in our case. Firstly, an area where the baffles don't conform around a strengthening rib adequately and secondly where a LAME has taken some shortcuts in fitting new baffles and not running replacement baffle strip far enough forward to seal to the nose bowl.
I expect that when we correct these deficiencies that we will have quite even CHT's
