Okay, here we go again. Got everything put back together and cranked it up.
What the heck is up with my oil pressure? In the short vid I made it was running maybe 10 psi at 2900-3000 rpm. Actually I cranked it yesterday and seen how low the pressure was so tonight I changed the oil (store brand 30W) and replaced the filter with a Wix 51348. The vid is after the fresh oil and filter change.

When I rebuilt this I did not tear the oil pump apart, maybe I should have? I checked the oil pressure bypass spring and it was in spec so I didn't change it. I guess at this point I'm going to order a new bypass spring and see if that takes care of this issue. On OnanParts.com they tell you to replace the spring on a rebuild or overhaul. Now it's going to be a pia to install this little $6.00 spring.
Does anyone have an oil pressure gauge on their Onan's and if you do, what pressure are you guys running?
