OT- 98 F-150 5.4 removal/replacement

Dad has a 98 F-150 and his 5.4 has crapped out with only around 135k on it - 40 psi on #3 cylinder and missing/fouling the spark plug in only a few miles.

Looking at either junk yard engine or a short block (it had new heads put on 5k ago due to pulling a valve and blowing a spark plug) that is reman. I'm going to be home in November for a couple weeks and thought I could do it at that time, but have questions on how hard the engine is to pull...

Anyway, how hard is it to pull the engine? I've had some people tell me you have to remove the whole front clip to get it out, some say just the grille. Anyone done this before?

Thanks for any help or experience you can offer with F-150 or Expedition engine pulling!

I'm actually in AZ, had to move a few years ago for a job!
96 Thunderbird LX 4.6 SOLD!
94 del Sol S 124k - 42 mpg
01 Accord LX 89k
I was once against imports, then I drove one...

I have never done it, but I would assume it could be pulled by just removing the radiator. In my '97 it seems like there would be plenty of room. Maybe a '98 is a little smaller of an engine compartment?

Currently In the Short Bus Garage:
2 - '94 T-bird LX's 4.6L (one with 300,000+ miles and one with 200,000+ miles)
1 - '97 Mark VIII LSC - INTECH V8 (120,000+ miles)
1 - '97 F150 XLT 4x4 Flareside, 4.6L (130,000+ miles) - Currently being dismantled and rebuilt with upgrades!
1 - '00 Mustang GT (likes to accelerate with the brake on!), 4.6L (60,000+ miles - only comes out when I need to get somewhere fast.)

oh yeah, and they all have 4R70W's

Yes removing the cab is the easiest way. But you can do it the other way if you want.

Any way you pull it, stay away from the late 90's 5.4 SOHC motors...everyone I know that has had one ended up with more work than owning an early 90's explorer. For some reason those motors were just junk.

Now a Navigator motor would be worth having. And the Late 90's Navi motor came with a Forged crank.

I dunno where these people you know are from,but every 5.4L I've ever dealt with has been relatively trouble-free...even in fleet towing/hauling applications. I deal with 10-12 different trucks with that engine on a regular basis-several of them are over 150K miles,with one of them right at 200K miles now with no mechanical problems. And the 97-98 5.4L's all had the forged crank you're referring to.
