Is there a port where you can connect a manual oil pressure guage on a 2005 5.3 LS engine, to check the actual oil pressure?
You take out the oil pressure sending unit and screw it in there.
can you then crank the engine without re-assembling
Yes, just turn it over with the mechanical gauge hook in the port. Leave the oil sending unit un-hooked from the wire.
Thanks, Looks like the best idea I've heard
