    98 expedition 4.6 engine swap

    I know what you mean. I think it was about $900 for for me to rebuild mine but that was with a new crankshaft with matched bearings, all new cloyes timing components, new oil pump, all new gaskets and seals, one new connecting rod, new piston rings for all pistons. I got all this from the dealer...

    98 expedition 4.6 engine swap

    I can say also that rebuilding a 4.6 or 5.4 is not that difficult either if you wanted to go that route. I bought our 02 Expy with 200k miles with a rod knocking for $1200. Got the motor out and rebuilt it in my carport. Have put 100k miles on it since then. Or ya know you could do the swap and...

    98 expedition 4.6 engine swap

    Yea all 02 models should have been PI equipped. Was just looking and reading and I think the sensors won't be a problem other than maybe their location vs locations of where yours are currently and if there is any extra sensors that the 98 doesn't have you could leave them unhooked and use your...

    98 expedition 4.6 engine swap

    Ok. So apparently in 2001 some but not all truck had the updated PI heads and intakes. Best way to tell is to pull the intake and see the port shapes or find the casting numbers on the head. A PI should say PI. Pic shows non PI on left and PI on right.

    98 expedition 4.6 engine swap

    Did a little reading and with the difference in the ports the intakes are not interchangeable. They make an adapter to put a PI intake on non PI heads but not the other way around. Let me look into this a little more to see if I can help you out.

    The updated heads to my understanding was an improvement in the ports to flow more freely. As I stated earlier you can put the PI heads on an earlier engine. I may be wrong best way to know is look at the ports and bolt locations on both heads.

    98 expedition 4.6 engine swap

    I would use your current intake, fuel rail/injectors, air cleaner assembly, basically everything from the air filter to the intake. That should will keep all your top end sensors the same. 98 and 01 are essentially the same except for the intake and being COP vs a waste spark style ignition and...

    4.6 timing question

    To clarify my 98 f150 with the 4.6 does have the imrc valve. Or at least something stuck of the front of the lower portion of the intake lol.

    4.6 timing question

    It may not. I know my 98 f150 with aluminum upper intake and plastic lower portion does have one. But on a brighter note I decided to do the carb cleaner trick one more time and did find a leak on the gasket between the upper and lower portion of the intake! I guess maybe with the clogged cats...

    4.6 timing question

    Would a bad or stuck/broken IMRC valve cause lean codes only with no other codes and cause the rough running drivability issues?

    4.6 timing question

    This one has 170k. My truck with 4.6 has 201k and my wife's expy with the 5.4 has 300k. I rebuilt it at 200k. That was the first time I've rebuilt a ford modular.

    4.6 timing question

    Eh. I always buy cheap broken stuff (often to my wife's dismay lmao). I did mean to mention I did do a compression test and all cylinders were within a few psi of each other, can't remember the exact numbers but we're well over 100 and from what I've read anything over 110 is acceptable on...

    4.6 timing question

    The thing is though if they were not firing should that not give me mis fire code?

    4.6 timing question

    I may be over thinking everything just being frustrated lol. Luckily no inspections required at all where I live! The times I've heard of people loosing a tensioner or guide they had a lot of noise from the chains and valve train which I do not have. It's gotta be something I'm over looking. I...
