Does anyone have a picture of this valve and pictures showing the removal of the valve. Lexus first told me 9 months back I needed a battery when it wouldnt start. I replaced it. 4 months later Lexus told me I needed a Alternater when it wouldnt start. I replaced it. Now 3 months later I'm told it is the ISAC valve. I only have 44,000 miles on this car. Thank you!
