Hey guys,
Have a 2005 f250 with 250,000 miles.
Recently did oil cooler, egr, stc fitting dummy plugs and stand pipes.
Had one of new dummy plugs fail. During air test.
Replaced and my question now is...
When I do air test I have a very very slow gradual loss off air on gauge during test.
Here nothing leaking now.
Is the slow loss normal or possible injector o rings or something else.
Thanks
