Head removal 99 expedition 5.4
I've got a 99 expedition 4x4 with the 5.4. I need to have the pass side head replaced because of a spark plug blowing out, and the helicoil fix not working. I've talked to two different mechanics, one says you have to either pull the motor out, or unbolt the body and lift it up to get the heads off, which obviously would be a ton of work. The other mechanic says he can do both heads no problem without removing the motor or lifting the body. Who's being truthful here? Obviously the first guy is wanting a lot more money for the job than the second. Any advice would be appreciated.

Lifting the body off isn't that hard. The downside is you need a lift to do it, which most don't have at home.

But like fordno1 said, it can be done without removing the body and without pulling the engine. Due to uneven wear and tear issues, I recommend that you replace both heads, not just one.

Thanks for the fast responses guys!
It's good to know that this can be done without pulling the motor or lifting the body. I'll go with the second guy, his quote is significantly cheaper, plus he's done good work for me in the past. Alloro, I'm going to have the driver side head removed too and machined along with the replacement head so they should be equal, and this way I (hopefully) won't have to worry about the head gasket failing on the driver's side in the future either.
Thanks again.

You won't have to worry about the head gasket but you will still have to worry about another spark plug blowing out. Replacing the head with one that has the extra spark plug hole threads would eliminate that possibility.

Well, to be specific, the helicoil is actually working as far as holding the plug in, but I now have a missfire on that cylinder. So the head has to come off to investigate, and I'd rather not mess with this head anymore.
