So I have noticed for quite some time that my ADBV seems to quit working after a track day. I would think that higher oil temps are what does it but i was curious if anyone else had this issue? I can put a new filter on and the oil light goes out instantly when I start the car. But if I do a ~20min track session, it will take a second after I start the car for the oil light to go out. Was curious if anyone else has noticed this?

I'm gonna try a Purolator filter to see if those hold up any better.

Whenever I change my oil filter there is always a lot of oil left in it so I assume my ADBV has never failed. I use a WIX 51344

 

Oh wow. That cleared things up a lot. Thank you!

 

My Google-fu is strong.
