Ok, my car only seems to be running on 1 rotor. So, I took out the top plug one at a time. With the throttle all the way down, and i turn the engine over the engine has NO compression on the rear upper plug. No pulses whatsoever. If i take my finger off the plug hole i can faintly hear a light flub flub flub noise.

The front has good compression with 3 equal pulses.

Now, does this still sound like an apex seal? From what i gathered, if an apex seal
went bad i should have 2 pulses and one dead. Mine would have to have all 3 apex seals out correct? How could they all go out at the same time? Is there ANYTHING else that would make this happen? Thanks for the help!

Sounds like a gouged rotor housing. Happy trails.

flying metal in an engine can do extensive damage, 3 broken apex seals is not totally uncommon but it is more likely that the housing is just so worn that the 3rd apex seal just can't build compression anymore like blackplague said.

yeah, start rotor housing shopping.

Ok, My car is a S5 TII. What all rotor housings will work in my motor?

i had the same problem as you and it turns out i spun a bearing and fudged up both the center plate and rear iron.
