Yep that is the way to do it. I had ford racing gears put in mine instead of stockers. To go with better parts is always nice. Do not go in with any aftermarket parts on the car or tune.You can be sure if it happened to 5 people on the planet it would be considered a “common problem”. A big downside to forums is that any issue with any consumer product will get blown WAY out of proportion. I the “old days” 50 cars could have the same problem and it would never make it to the level of “common problem” because firstly 50 incidents don’t make for a common problem and secondly there were no forums for all 50 people (an incredibly small percentage of the market considering the 5.4L 3v F-150 motors are the same) to get on and complain about it.
Rest assured something strange happened. If it was a weak point in the engine design there would be an endless amount of information about it.
If you play your cards right (I.E. don’t be a **** about anything regarding the repair, timetable, Ford rep, etc) and there is enough damage done to require the head and or cam be replaced you may be able to talk the Service Manager into replacing the OEM parts with FRPP stuff if you pick up the difference (for the other bank of cylinders). When I owned my dealership (a motorcycle dealership) and something in a motor let go and it was a warranty job the motors ALWAYS went back together with the “good stuff” and the customer in most cases didn’t need to come out of pocket very much to make up the difference and came away with a massive performance upgrade.
More than likely there isn't a difinitive answear for this.:headscratch: When you consider that there are 24 rollers in every 3 valve engine built since its inception in 04 (something like 100000 engines?) Thats only like 2 million or so. There is bound to be a failure or two. Yours is the first I have heard about. I know this doesn't make you feel any better but at least Ford is picking up the bill. Did they give you something cool to drive while they fix it?any ideas on what causes this, dealer is uncertain:headscratch:
