Hey all, I've got an '88 rx7 t2 with an s5 engine that I'm troubleshooting currently. It's my first rotary and I'm trying to figure out what's up with it. I followed others' instructions on how to compression test (remove the valve and check for even pulses) and here are my results, please let me know if they seem good.
There are two videos, one for each rotor.

Please let me know what you think, if it's good it's just one more thing to cross off the check list!

The gauge is impossible to read in the video.

What you are looking for are three even pulses above about 80 PSI on each rotor.

 

The marks are at 30/60/90/120, try full screening it at higher resolution. It appears to be be slightly over 105 peak. It doesn't look like the other videos I've seen of a blown seal.

 

compression looks and sounds fine, start looking elsewhere.
