Is it possible for me to inspect my intake valves without removing my intake manifold? Could I for example use a borescope camera and go through the PCV inlet on the intake manifold and maneuver it around to see the intake valves? Or do I have to remove my intake manifold? I’m trying to avoid doing so because I don’t want to have to replace the gasket. I’ve heard you should replace your gasket every time you remove the manifold, even if it’s not leaking?
Does anyone have like a video showing how you inspect your intake valves with a borescope camera. Like not footage of the valves, but actually showing how to move the camera around without taking the manifold off.
