Most of today was spent working on engine related safety items. In a recent blog William Wynne discussed the risks of mounting pressure sensors from their 1/8 NPT fittings. I had not heard of this type of failure, but given WW’s experience and concern for safety, I decided that if he was concerned about it, I was concerned about it.
This was an issue with two pressure sensors on my engine, so I looked for simple and light solutions for both. For the oil pressure sensor, it was mechanically stabilized with a pair of cushion clamps securing the sensor body to the adjacent intake manifold. The oil pressure sensor was stabilized with a formed bracket mounted to an adjacent Gold oil system mounting bolt. The upper end is clamped to the sensor body with a hose clamp. These devices support the upper mass of the sensor, preventing relative motion,
The break in oil filter was also safetied by drilling a small hole in the extreme corner of the filter adapter for one end of the safety wire, and adding a hose clamp to the filter for the other end. The hose clamp will go away when the flying filter (K&N HP-1008) is installed after the engine break-in. It has a safety wire feature at the top of the filter.
