Today I tried to install the Dynon supplied oil temp sensor on my new (from Van's) IO 360 M1B. Unless I am misinformed, this sensor installs on the port that is just fwd of the oil filter on the oil filter adapter, and is facing upwards. To my surprise the threaded portion of the sensor (Dynon Part No. 100409-001, 5/8") is a bit too small, and just drops into the hole. This is the larger of the two sensors that Dynon supplies according to the installation manual, and measures approx. 9/16" dia on the outside of the threaded portion. Anybody seen this problem?
