Want to install a manual oil gauge in my van as the pressure seems to change quite a bit. Some say oil pump is bad, others say bad voltage or PCM. Can not find correct thread size to "T" off where oil sensor is. 16 x 1.5 mm seems close but not sure. Thanks
In this Video... Alumnas GMTN Member @MAY03LT describes the Oil Pressure Tester Adapter (by name and Part#) and provides the "HOW-TO" information for its installation and use with an Analog Oil Pressure Tester Gauge:
Yeah, the 6.0 truck engines have been known to lose pressure as they age along with the issue with the pickup tube O-ring. I've seen some replace the oil pump with a high volume and pressure pump to solve it.
