Low Oil Pressure ?'s
- Thread starter Deuling
- Start date
Oh yah lol, Ive been considering a rebuild, but idk if i should take this motor out and spend $500 to put new pistons, seals, bearings, valves in. Or find a 350 and do the same. I just figured it would save most money to rebuild one i have. Ive also never touched an engine as far as a rebuild.....
Im still gonna replace the oil pump, maybe the screens clogged up or something idk.

Did you ever put a mechanical gauge on it to see accurate oil pressure...or are you still believing the stock gauge?

I got a new gauge, but i have no idea where to run the plastic tubing too....
They sell little brass fittings that have a pipe fitting on one end that matches the fitting on your sending unit, and a fitting on the other end that the tubing goes to.
You pull the sending unit and screw in the brass fitting and hook the tubing to it.
Thats if you want to either replace your factory unit completely, or just make quick test.
If you want to keep both, then buy a "T" that has one male pipe fitting for the block, and two female pipe fittings for the sending unit and tubing fitting.
I think the pipe fitting is 1/8 inch pipe, but check with someone else here. I'm more comfortable quoting Fords.

Yah lol i work for a plumber so i got the T thing lol, but where is the sending unit?? thats my prob i have no idea where im hookin it too, it came with the fittings.

keep in mind always figure in at least 50% more time and 50% more money than expected for a rebuild. Never gotten a crate engine but I'm sure you could expect the same.
Look by your distributor, you'll find a sensor with a wire on it...unscrew it, replace with what you got with the gauges and go from there.

a wire? I thought it was tubing lol. Now im all kinds of confused haha
Well, you are replacing an electric gauge with a mechanical one.
The electric one works just like your gas gauge.
There is a diaphragm inside the sensor with a spring. As the oil pressure builds, it pushes against that diaphragm and compresses the spring.
That moves a wiper across a resistor which changes the resistance in the circuit going to your present gauge.
Gas gauge works the same, except it uses a float to move the wiper.
So, your sender might be bad or changed values, the gauge might have electrical problems, or you could have a bad wire.
The new gauge eliminates all that. It just has tubing which carries the pressure to the gauge which moves against a spring.
Thus there is less to go wrong. Which is why you use a mechanical to check the electric one.

Lol damnit i was lookin high and low for a small piece of tubing not a wire lol.
Well, naturally. You're a plumber, not an electrician.
