oil pressure questions
I have a 72 ford f100 ranger with a 360 and i think something is wrong with my oil pressure. When the engine temp is at 195 and at idol the oil psi is 10 to 15. now that sounded pretty normal from what i read but i heard of people getting up to 40 while accelerating and with me floor boarding the truck i may get 25. Is this ok? i just dont want to ruin my motor because i didnt do anything about this
Any help will be wildly appreciated

By todays standards of what we know about pressures, no way, but for the old FE that is well worn it is perfectly normal. The FE oil flow goes through the crank area first, when it gets hot and the bearings expand more oil can flow through and the pressure goes down. Just make sure there is oil in the pan and no worries.

IMO - That amont of oil pressure is better than none, but not what I would want in an engine. Are you sure the guage is correct? It may be off a bit. Otherwise I would instal a new high flow oil pump if the engine has a lot of life left in it. If the engine is nearing the end of it's life, just go ahead and run it until you can afford to rebuild it.
My 460 is always over 40 psi and it's not a new engine.

I used to have an engine that only had about 10 psi or a bit less. I drove it around like that for quite some time until I could pull it out for a rebuild. When I did I found that ALL of the pistons had broken skirts with the pieces laying in the oil pan. It was because the oil pump was worn out. Be careful or just put in a new high flow oil pump.

dilmachender, Check your oil pressure on start up after it has rested over night, I'll bet you a cold RC cola that the pressure is higher. It is only after it reaches operating temps that everything expands and the pressure go down. It will run for years more just like it is.

Some guys racked up 200,000 miles on these fe with this low oil pressure.
Some guys drop down to a 180* temp thermostat run some STP to the oil as this will
bring it up about 5 more PSI while idling. And use a little heavier eng. oil.
A lot of oil PSI is lost at the rockers that causes this low oil pressure in the fe motors.
Now you take a fe motor that was built with adjustable rocker arms with non hyd lifters the oil that would feed the hyd. lifter is plugged off. These motor had upwards of 30-40 psi while hot and idling. Due to less oil loss throughout the system as it made it's way to the rockers..
