Question: Once you reconnect the oil pressure line, do you have to bleed the oil line that goes from the engine to the indicator? | | | | | Joined: Feb 2004 Posts: 29,818 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,818 | No need-- - - -if a few bubbles are in the line, they will compress and give a correct pressure reading. Don't be surprised if a 216 has little to no oil pressure at hot idle. Spray-oil engines can run with 15 PSI or less oil pressure at hot idle, and even less is not uncommon. 235 full pressure engines will have quite a bit more, but one with a lot of miles and some rod bearing wear will also be lower on pressure than most people are comfortable seeing.

It will run briefly at 15+ psi at cold startup.

This 216 engine also had a disconnected low oil pressure switch and light. I have just rewired in the light. | | | | | Joined: Oct 2021 Posts: 6,833 'Bolter | | 'Bolter Joined: Oct 2021 Posts: 6,833 | Texas, do you have a shop manual for your truck?
Those are the pressures listed in the manual for a properly functioning engine so as long as my engine (and yours) operates withing those ranges, I don't worry about it.
People used to modern vehicles with 30-80 psi get nervous with such low pressures but it's perfectly normal for these engines.
