When it starts up (cold), the pressure climbs to about 50psi at idle, but jumps to around 70 at 5000rpm. After it warms up, it stays at about 40-46psi while riding, and about 20-26 at idle.
It used to cold start at about 40-50 psi, but would not go above 50psi even if I revved it. Warm idle was about 15 psi.
I used (and have been using) Rotella T6 5w40 oil. The only thing I used different was the oil filter. This time I used NAPA Gold 1356. I typically use WIX 51356. This is the first time using the NAPA Gold filters.
I checked my oil pressure relief. I could not get it out of the hole, but I do know it slides up and down in the hole. I could crank the engine, and watch a bolt that I put in the hole slide up and down. So I know it at least works somewhat.
Anybody using the NAPA gold filters noticed an increase in pressure ? I’m not sure if they have some type of pressure valve in them ?
