I am in the reassembly stage of an extended project on my 98 Expedition 5.4.
I tapped in new Cal-Van inserts into the heads to repair spark plug threads and prevent failure in the future.
Part of this process had me blowing out the shavings from the cylinders through the spark plug holes and cleaning the threads with brake cleaner (which in turn entered the cylinder) before installing the new inserts. On top of that, this process mixed in with my job has had my truck down for several weeks. I work on it when I can.
At this point the cylinder walls and rings are going to be bone dry and the procedure was done with pistons at bottom of stroke with valves closed.
Anyone have any ideas how I can pre-lube the cylinder walls and pistons through the spark plug holes before sticking in the new plugs so the cylinders and rings won't be completely dry on initial startup? Something that won't foul up the new plugs or cat converters.
Also have access to intake valves since the intake manifold is still off, but seems like the spark plug hole would be the more suitable access point to work through.
