90 PSI Oil Pressure.

From my experience, doing maintenance and then experiencing a problem are usually related. The only way you’d see higher pressures at idle after maintenance is that you induced a foreign object into the oil system and it has created blockage or it’s simply a coincidence that the sending unit has failed.

You serviced the engine with the same weight oil? Different filter type? Engine was at operating temp? What were the previous pressures prior to maintenance?

I replaced the filter with a quality WIX filter. This is the same type and brand I took off of the engine. U gave changed the oil 3 times in 300 miles because if leaks. This is a fresh 418 stroker and I have been very careful about cleanliness. It does have a remote filter setup on it and a oil cooler. Maybe there might be an issue with the filter. I have spares, maybe I should change it.
