Compression test gone wrong!!!!

[import93_123]

I just got a 95' 240sx. When I went to do my compression test, I screwed on the 14mm adapter to the compression tester tube, screwed it in to the first spark plug hole and did my test(it came out around 180psi). When I went to unscrew the tube it left the 14mm adapter in the spark plug hole ! I don't know how to get it out, am I screwed or is there a way to get it out. There is a 11/16 bolt around the adapter and I thought I could just take a socket and get it out but it won't fit. My friend told me I need a thin wall socket. Is there a such thing and If there is do you think It will work. Thank You

yes, or just try reattaching the compression tester hose to the fitting, be patient, and then unscrew it

I did the same thing this weekend. did a compression test and the adaptor didn't come out.

I went to the hardware store and bought blue thread lock (Red one was more expensive). Put the thread lock on the hose threads, screw it back in, let it sit for an hour and go back and unscrew it.
