If you're burning oil your plugs will be partially fouled and will throw off other tests. Change the plugs and coil packs while you're doing the AOS work.

Those 997.2 manometer readings for the normal scale are about 3x what a 997.1 is so that engine runs with a lot more vacuum for whatever reason.

 

just looked up the kit for the .2 its 744 compared to the kit for a .1 just under 300. Think I will go with the AOS it self and if a hose breaks ill change it.
