Throttle Response and Failing AOS

Oddly, last time I checked I had very little suction on the oil filler cap. No smoke. The things seems to be stealthily failing..

Would this situation affect proper throttle response from 3-4K ? I would think it would if you trying to combust too much oil/vapour. I have been chasing this problem and I think this maybe it.

Is there currently a better motorsports AOS that can go in a 2000 S ?

No MS AOS is made for the 2003 up style AOS engines.

AOS diaphram degrades & begins to tear. Oil in cylinders begins to foul the spark-plugs.

Check your plugs starting on Passenger side.

Okay I have just finished about three hours running time: highway, country and gridlock......yah TO has it really bad right now

I pulled the oil filler cap to check for suction and there is enough to hold the spring loaded oil filler funnel until I knocked it against its upward stop....so perhaps approaching the suction force of an old worn out vacum cleaner and I can get a hissing noise happening by hold the cap close. Is this normal suction? I would say no myself...

Also covering and uncovering the the filler funnel a few times disrupts the idle of the engine and one can feel the engine react to the vacum change. Again, not knowing the inner workings of the AOS, it feels like the AOS is packing up. Anyway it's odd that most only see the smoke screen and then they know

How would this AOS condition affect throttle response??

It would appear that a high performance AOS is available for from Pelican and if you check it out the listing seems to indicate that it will fit the above. Is this correct??
