Poor man's compression test question
I'm having issues with my car that led me to do a compression test on my car. I bought a regular tester which does not fit in my engine, so I decided to do the poor man's compression test detailed by aaroncake. I have the lower spark plug removed from the rotor chamber closest to the fire wall. I turn the engine and I don't hear ANY "psst" sounds at ALL. I'm not sure if it's because my battery is slightly low (although I plugged in an electric battery jumper pack) or because ALL my rear rotor seals are blown.
We first tested the rotor closest to the front of the car, although we stupidly removed the top spark plug instead of the first, we did the test and we had steady "psst..psst..psst" sounds of good compression.
I need help, fast!

Compression tester for some reason wouldn't fit in the hole. I don't really know lol. Thanks for responding though. I know you're super knowledgeable. Thanks for trying to help :/ I appreciate it a lot.

no sound is a pretty definite conclusion of no compression. no compression is due to carbon stuck seals or broken seals ejected from the engine.
you can try some lubricant in there to unstick the seals or use a mirror and look through the lower plug hole and see if the apex seals look chunked.
