ACDelco D1829 Professional Engine Oil Pressure Sensor: High-Performance Precision and Reliability Review

I used this on my 1986 Olds 442 with rally sensors. This does not apply to vehicles with a warning light on the dashboard. It's well made and works great.

The seller has sent an item that is clearly used. Yellow paint around the top of the sensor as if it has been marked as a junk item. The red thread sealant was removed when installed on the engine.

A mysterious oil leak on the new SBC has been fixed. I didn't know these things were leaked. I was confused lol. Now I have good oil pressure and the oil leak is gone for good. I had to replace them during the engine overhaul.

I used an industrial pressure gauge to test, it is accurate at 30psi and 60psi. Because of its size, it will fit the HEI manifold on a Chevy small block engine unless you use a 45 or 90 degree elbow. Admittedly, my car is an older model, so a later model might already be using a manifold or a different oil pressure port.
