Same year simple exchange... misc brackets or accessory might need indexing. as long as engine series is not different OF, course replace the awful Ford design 2 piece spark plugs when the engine is out, all these 5.4 3valve engines (photo in my garage) have the issue (breaking plugs) until 2008 correction.

@ Auto_Centric Is there any difference in the cam phaser? My sons is a 2004.5 F150. The guy doing my swap is giving us the run around saying he has to get new timing chains and cam phaser before he can finish Had the truck for two weeks...


Did he mention the plug problem or VCT's too. Possibly just doing a through job replacing the cam chain and phasers? They DO FAIL..did the pin shear from the cam are they "loose" even on a lower mileage engines.. ask him lots of questions, I can purchase a complete chain kit and phasers Vct's like now one call done! two weeks no excuses the guys slow..I never wait for parts even if it means $100 overnight shipping fee, my clients don't wait no need when scheduled this engine exchange is a two day service not two week unless he's doing it for a few hundred dollars, if you're willing to wait.

No just wanting to charge me an extra $500 to change cam phaser and chain


It's actually a good idea cause these phasers tend to fail rather quick. I've seen it as early as 60k miles. $500 is a good deal but if it's OEM
