I do that sometimes when the car has not been started for a week or more. I have replaced the o-rings on the shaft that goes through the oil filter. The oil pressure came up quicker for a while. Seems like all too soon the delayed oil pressure problem returned.\
I'd say if we bought an ample supply of those o-rings and changed them with each oil change our delayed oil pressure would cease.
Does anyone know if the nitrate o-rings sold by Harbor Freight are suitable for this application?
