How To Do A Compression Test On An FC?
My car has bluish/white smoke coming from it at high rpms so I'm planning on doing a compression test on my n/a sometime after Christmas and I'm not sure on what to do. (This will be my first compression test)
Do I take out all the plugs at once, take only one out and do the test one by one, or is there something different?
What am I looking for/how many engine rotations do I do to get the results to be accurate?
What numbers am I looking for?

Except this part:
Remove the schraeder valve from the end of the gauge, and the numbers will be much more meaningful. FSM spec is ~85 psi minimum.
8) observe the needle bounces. You should see 3 in succession without skips, even bounces, in roughly the 30-35psi range.

How Do I perform Compression Test on Rx7 1991?
I currently purchased an Rx7 2nd gen fc 91 and was wondering how to do a compression test. I've look at many forums and videos and can only seem to find information on Rotarys that have 1 trailing plug and 1 leading plug; my rotary engine on the other hand has 2 trailing and 2 leading. How would I perform the compression test? PLEASE HELP!

there is a front half and a rear half to a 2 rotor Wankle. Each rotor has its own trailing (top) and leading (lower)
good luck, lots of good info out there.
