Oil pressure testing is one that many mechanics ask me about. The question is how do you do it? and what tool do you use?

The problem is that if you remove or even disturb to oil pressure sensor, you may have just temporarily masked the problem. I always want to compare what the engine oil pressure shows on the dash, and compare it to what a mechanical gauge shows.

With this in mind I came up with a solution:

1) Get a new oil filter off the shelf for the car you are working on. [Removing paint]

2) and grind the paint off the center bottom of the filter

3) Solder a fitting to the bottom of the filter. [Tools needed] [Soldered on ]

4) Poke a small hole through the inside of the fitting. [Poking hole]

5) Put it on the car and connect the gauge [Complete assembly]

Now you have an easy to use oil pressure gauge that you can drive the car and still see the oil pressure on the dash. My collection of adapters [Saving filters] Here is the part number for the fittings [Fitting] [Fitting]

Hope this helps someone in the future. David
