Help me diagnose, with compression results.

Help me diagnose, with compression results.
So I was driving to work the other day and cruising and had a few stutters then lost power. Got the car to start again but would only run if I was fluctuating the throttle. If I held steady anywhere it would die. Got the car towed home, charged the battery and it started like nothing was wrong. A couple days later started it and moved it with no problems. Since then I can't get it to run without the same revving of the engine, any static throttle and it will die. Took a compression test and it looks really good, except for one chamber on the rear housing. Front rotor looks the same except all the are good. Seems like a bad apex seal would reduce two cycles wouldn't it?

I am curious if anyone has any idea with a result of 0, would this likely be stuck side seal, flattened spring or broken side seal. Also, I've never lost a side seal before. How does damage of side seal compare to apex seal? Can the side seal actually work its way out like the apex seal can?

Yep, side seal issue. Impossible to know exactly what until you open the motor up, but that's the only way you can have zero compression on just one face.
No amount of trickery, chemicals, or good wishes will fix it. You will have to open the motor up. With any luck you have everything else in the motor happy so you just need to fix whatever is up with that side seal.

might as well. its a lot of work, but if you know everything is right there is some peace of mind there (along with some reliability)

Once you start un-stacking the motor you are committed. You can't just fix the rear and put it back together. Pull apart, clean, re-stack. Also the sealant all has to be re-applied - once you open it up the seal is broken.
