how could i tell if my motor is original or been replaced?
does anyone know how to check the engine numbers or where? My dads mech, if thats what he calls himself, supposedly put a "low mileage" motor in his 97 F-150 5.4L.... but i found some things i rigged, i mean "modified" that says otherwise... any info would be mucho appreciated. the motor mounts look like they have always been there, it just looks like someone changed the valve cover gaskets is all. plus it had a "misfire" which was still there with the "new motor", he said it needed a cat is why it ran like that! thought you were supposed to fix the problem first, then repair the damage it cased! but whatta i know... I cleaned the dpfe thingy like everyone here says and so far it runs like new... didn't cost me much compared to the couple grand his mechanic charged! hope I'm wrong, but if not pops should get his dough back! plus, this dude is my dads friend! Think the right thing to do here is ta kick his A@#$! after court, of course.... thanks in advance, this site has already helped me soo much!
