Plastic pieces went into the intake manifold what can I use to remove it
I know it’s a pain in the arse, but I would remove the intake, and recover that bit of plastic, for peace of mind, if nothing else.
A powerful shop vac might work but to be sure, pull the manifold AND vacuum the intake ports.
This is what I would be worrying about . . .
Just where did the plastic come from . . . ?!
What is breaking apart . . . ?!
