[Boss 5.4]

I have full exhaust inc Extractors and a cold air mod. My car went on Oil watch and about 4 months ago Ford rebuild my engine to fix the problem. Not once was any of my mods mentioned. The issue had arrisen prior to the extractors etc, and I had the paperwork on hand to prove that the oil issue had been raised before the mods went on. They were good on this issue as I expected it to be mentioned.
