Lost all compression on second rotor?

Alright I did a compression test and one the first rotor read great bouncing 3 times to like 100 maybe a little past. The second rotor gave nothing at all. This is a result of bad apex seals right? wouldn't it take all three seals going bad to register nothing? wtf!-

usually two are bad if you get nothing - do your self a favor and dont crak it anymore. If any pieces of apex are loose you could wipe out the rotor housing if its not already toast.

or if your creative you could have lost one apex and one side seal

odds are though the seals are stuck.

i have a motor on my bench that none of the seals are broken but 0's across the board on back and 30's on front.

rebuild?

Sess- How ya tell if they are stuck? If they are what is a good way (if any) to get them "unstuck"? I don't think they are stuck though. The problem occurred outta the blue one day, not like the car was sitting for a long period of time.

see the engine that I got was sitting for awhile -

some ppl try ATF but that's usually for carbon lock.

just go with a full rebuild and get a cherry engine again.

My friend, your looking for a shortcut when you possibly have major engine damage. When the engine has sat for a LOOOOOOOg time, unsticking them is an option. If this failure has happend during a peroid where the engine has been running, well, its not a pretty site.

Well, my engine did roughly the same thing, and is currently in pieces on the floor of the basement awaiting the rebuild kit to come on.

Rear rotor & housing are toast, front housing is questionable at best.
