[QUOTE="JAJ, post: 15730067, member: 131874"] There's a pretty extensive bulletin on the Motorcraft service website that Ford techs use that outlines how to identify modifications and what symptoms they may cause. For instance, "if you have damaged pistons in an engine, then look for the following things...". They show pictures of headers, CAI's, blowers and other non-OEM stuff. They also go into considerable detail on how to detect non-standard software ECU tunes, even if the software on the system the day they test is stock. There are counters and switches in the ECU that will reveal that non-standard software was installed, even if it's now long-gone. They don't say to reject warranty repairs outright, but they do explain when to raise questions with Ford directly. If a tech sees burned pistons on a car with a blower, it's likely that they'll reject warranty coverage. However if there's a [LEFT][SIZE=4][FONT=Verdana][COLOR=rgb(204, 204, 204)] leaking water pump on a car with a[/COLOR][/FONT][/SIZE]n aftermarket exhaust, they'll probably say fix it.[/LEFT] [/QUOTE]
