So it looks like one of my frost plugs in the head of my 4.0L has given up the ghost. Ive taken it to a couple of local mechanics and theyll either not do it or have quoted $2K. Its the one on the back of the head between the firewall.
Does anyone know how I could fix this without pulling the head, or should i drop my spare engine in it cause this ones been neglected quite badly it seems.

They are called "Freeze Plugs" not frost plugs. also pulling the head is not that difficult. also you could throw some new lifters in there and new head gasket if you do pull the head if this motor has indeed been neglected. if you took the head to a machine shop they would pop it out, clean it up and replace it, also have then surface the head to make it nice and flat!
Sweet as frost plugs is just the term the mechanics use on this side of the world, dont know why they always call **** by the wrong name.
Ive been talked into dropping my newer engine into it now

$2000 to pull the head and replace the freeze plug? That is easily a 4-5 hour job if you are mechanically inclined and $100-$150 in parts..
So Im looking at the ones in the 50mm range???
Gota love those 4.0L though

Ah...So your up side down...and can hear us all the way over here. I don't know the size but recently used clay to get an imprint of a hard to reach gap I needed to cut a shim for. 50mm sounds big for a head, but don't know. There are only so many EXPANSION plugs.
(Ok, I made that up)
(calipers here can be under $25)(slave labor)

Old school spoon man, doesnt think it really matters anymore. BUT I wouldnt bother replacing the lifters if they seem to be pumping up good.
Im gana rip the engine outa the parts Jeep I have this weekend and start making it shiny n stuff ready for a transplant. Just really want to get as much life outa this engine as I can before swapping them.

I just put new lifters on an old cam and no problems. One of my lifters collapsed after head replacement. So I replaced them all with new push rods. runs awesome!
U can put new lifters on an old cam, not old lifters on a new cam. As for the frosy freeze plugs, can also acces with trans pull and engine in. A good write up with pics on the gojeep-xj-info site. Mute point is your puttin in a fresh engine, new plugs in the swap in engine? Good luck with the swap.
