Correct Oil Pressure
Does anyone know the correct oil pressure for a 79 LTD II engine (though my truck is a 86 Bronco so that number may work as well)? I have searched Gary's site and still couldn't find anything. I was installing the oil pressure sender and its says 3-8 psi on the bottom. Will this be enough?

Great! Thats a good rule of thumb I didn't know. I should never get over 6000 rpm so I should be good.

As a guess the 3-8 would be for a oil light. When the psi drops between 3-8 and lower the light would come on.
The 0 - 60 would be for a gauge even if it is marked" L to H".
Sometimes the owners manual will show what the L & H mean but not 100% sure on that.

Some of the more technical members will come in and explain better than I can, but at some point [mid 1980's?], the Ford engineers decided to use what some refer to as a "dummy" gauge. It looks like a normal oil gauge [L to H], but in reality, it does not actually read the oil pressure like an aftermarket gauge does. The sender is set-up so that at something like 3-8 PSI, the "fake" factory gauge shows above low and then at a greater pre-set oil pressure, the "fake" gauge shows to be in the normal range.
I initially thought you were asking what range of oil pressure an after market oil pressure should be?
If you are replacing a defective sender for the factory gauge, I would recommend finding the correct Motorcraft sending unit, so the gauge will work as originally designed.
The "rule" I quoted is what is considered a minimum oil pressure for engine safety.

I believe this would be the one for a 1986 Bronco with 302 engine: More Information for MOTORCRAFT SW1547B
