Need help with a DM8 - Massive leak coming from front on/off INTERNAL BODY

I recently picked up an old DM8 from a friend that has been sitting in a closet for the last 4 years. I replaced every single o-ring that I could find on the gun (bolt, LPR, HPR, on/off) with brand new o-rings but I am still getting a MASSIVE leak from the front on/off. The gun airs up fine when the knob is off, but when the knob is turned on all the air pours out of the passage holding the internal body and into the solenoid tray. I'm not even sure if air is getting to the LPR at this point, it is all venting out of the on/off. As I said before I replaced the 3 o-rings on the knob itself. I haven't been able to change the o-rings on the body because the manual doesn't list the correct sizes. I know these on/offs have always caused problems with these guns, but I never really had this issue with the 3 8's I had in the past. My questions:

1. Does anyone know the size of the 3 o-rings on the internal body for the on/off?
2. Is there anything else that seals the internal body besides these 3 o-rings? It seems like a flimsy seal to hold all that air back...

I'm hoping someone on here might be able to help me out to avoid sending the gun to Dye.

no need to send the gun away. purchase a CP continous flow plug and replace the front on/off with it. the more you turn that retarded *** thing the worse your dm8 is going to get. not sure how to get to it on a dm8 but on a dm4 i can

I probably will end up going that route, but I'm not sure if that plug will really fix the issue. It seems like a LOT of air coming out of it.

the o rings for the on/off housing of the dm8 are 2 012's and a 014. if the gun is not leaking when the on off knob is turned to the off position, its more than likely something in the bolt or elsewhere in the gun.

As bryan said, I'd also just buy a CP flow plug as well.
