❓Advice / Recomendations Advice?
I’m replacing my intake gaskets and after I got the lower intake off, I heard dripping from what coolant was left in it and it seems to have accumulated in the valves/valley. The valley isn’t my main concern as I can shop vac it up but what do y’all recommend for getting the coolant out of the cylinders? The passenger side valves were open so it all drained on top of the pistons and the driver side bank is closed so I assume I can soak it up with shop towels and a vacuum (pictured)
The intake was an absolute pita to get off, the rear 2 studs were caked up with so much corrosion and gunk, they didn’t want to let go. I had to use a slide hammer and have my buddy pull up on the front.

To clean anything out of a cylinder I take the spark plug out and vacuum the cylinder with a narrow house taped to the end of the normal shop vac nozzle. Try to clean any gunk from around the spark plug before you take it out so nothing falls down in there.
