Hi all, I gave my fuel injectors a clean recently and after a couple of days I started having misfires in cylinder 1 with an error code stating it wasn't getting fuel. So I took the fuel rail off again but this time the injector in cylinder 1 stayed in the hole. I managed to coax it out but the black plastic cap and the brown rubber O-ring fell into the chamber. I have used an endoscope and can see the cap but not the O-ring, unfortunately I can't get the cap out yet. The piston is near TDC. I've taken the spark plug out and can't see anything. What is the likelihood that the O-ring has gone under the piston and what is the worst that can happen? TIA.
