After nearly 2 years, I've finally replaced my AOS!

Well at about the 3rd month of ownership 2 years ago, I realized I needed a new Air/Oil Separator because of 2 reason; 1) Puff of blue smoke every month or so. 2) leaking lots of oil from the bellows tube/accordian tube at the rear of the engine.


Between the time i noticed and the day I finally replaced the A/O Separator I've had a bad vacum leak and idle became progressively worse as time went on. So I bought the newest A/O S and J-Tube... Reset the cars computer and started her back up and BAM....... smoothest idle I've heard & felt from this car in over a year. And i can feel alot of lost HP come back in the Hi RPM's that wasnt there due to the vacum leak. I've driven it 98 miles since i did the AOS replacement and no CEL's and idle is still smooth and always just acouple hairs below 800rpm mark on the dash.

I've also noticed that Im not blasting through fuel as quickly.

Replacement took me about 40 minutes counting placing the top in service mode and replacing all the covers when i was finished.... I also pressure washed all the year in a half of oil and dirt stuck to the right-rear side of the engine as a result of the leaky AOS.
