The oil probe P/N 400505-C is installed by removing the 3/8 or 1/8 pipe plug located on the front of the engine inline
with the push rods. This oil galley feeds the valve lifters. Insert the JPI 1/8 NPT probe supplied with the kit. Check for
leaks after installation. Due to cowling restrictions the alternate oil location may be chosen. The probe leads are
routed back to the cockpit along with the EGT wires. Do not install the Oil Probe in the rear of the engine near the
vernatherm (oil temperature regulator).
