I wonder is there a way to figure the area of the four holes in the bolt and the area of the factory hole and determine if there is a probable decrease in the flow. I failed math. If the areas are similar would the change in direction of flow and being forced through four smaller holes instead of one big one make an appreciable difference?![]()
landtank said:can't comment on the wix filter but I'm pretty sure the OEM small has a check valve which restricts the oil from draining back into the pan. I remember on my old FJ60 how clean the oil changes were since the oil filter was upside down. Then I read about these check valves and tried a OEM one. Oil everywhere when I pulled the filter off. Now if driving a spike through the bottom of the can would allow it to drain then I'd like this mod for just that purpose.
RavenTai said:The problem with this is even if the ABDV works, and some do not, there is nothing to keep the oil from flowing out the filter outlet (big hole in the middle) the oil has several paths out near the bottom of the motor and a place for air in from the valve train,
elmariachi said:A question:
-- If the oil drains back after sitting, how come on the one or two ocassions I have changed my oil after letting the truck sit all night, the filter has still been full?
A comment:
--A long-time Toyota mechanic for which I have very high regard told me that the reason LCs have filters mounted upside down (or close to it in the case of the 1FZ-FE) was so that at start up, the full filter would discharge its contents down into the engine, lessening the amount of time the lower end is without oil and making it pressure up quicker.
I don't recall the FSM having a flow diagram so I am not sure where that oil goes when it leaves the filter, but I am assuming it is routed directly onto the main bearings.(?)
Thoughts/opinions?
