Bell 212 SCAS spares are becoming rare and eye-wateringly expensive. But if you're fire bombing (VFR) in an IFR Bell 212 with a dicky SCAS, turn off the SCAS and continue on with the mission in wobbly mode. Fix it when the parts arrive.

C-Box oil pressure oscillation
After a C-Box replacement, we noted a little oil pressure oscillation (less than 5 psi above and under 70 psi) when lifting external cargo loads above 90% toque and at level flight with the load, even at low power. Without external cargo loads the oscillation isn't noticeable.
The indicator and transmitter were also replaced, but the oscillation remains.
Does anyone have noticed something like this before? The other 212 of the fleet have no oscillations at all and the manual doesn't mention this condition (as a malfunction or not).

In your fortunate circumstances to have a fleet, why not swap gauge first (easy) and pressure sender later (harder) to see if the fault follows?
Thin ice for a pilot to make maintenance suggestion, engineers just want symptoms.
