I just purchased a 2001 Land Rover Discovery Series II. A friend of mine said he could do a tune up for me and i trusted him. I left my truck with him and went about my day. I picked up my truck and drove home. As i was driving, the truck started shaking and bad electrical smell came out of the engine. I made it home (30 min drive) and at this point the truck was in terrible condition. Horrible Smell, bad noise, shaking, etc.. I popped open the hood and checked the spark plug wires to find that 4 of them hadn't even been put in and that 1 spark plug was broken in the head. I spent the whole day today trying to take it out and replace it, but it's not even budging. I tried all tools i can find from "Grip Tite to Needle nose pliers". PLEASE, PLEASE im freaking out..can someone help me. I took a picture of the broken plug in the head.

 

You need a spark plug socket and a ratchet to remove the spark plug.
Go to AutoZone, bum a ride, take your other car, whatever and buy a cheap socket set, remove that spark plug and take it to them and buy another one, you want the exact same one.
If you still have the other part take it with you as it has the part number on it.
Then put it back in.

 

Maybe it's just the picture, but I don't see any wrench flats on that plug. I was thinking one of those "universal" sockets that look like a honeycomb with tines that retract as you push it onto a nut, allowing it to grip from many sides. I've used one of those to remove a badly rounded but before.

 

Maybe one of those special sockets used for removing locking lug nuts when you've lost the "key" would work.

 

I'm thinking one of those locking lug nut sockets is going to be too big in diameter to fit the recess in the head. This is what I was thinking of:

Gator Grip Universal Socket 3/8" 2121804

It has an outside diameter small enough to fit into the spark plug recess in the head, and is large enough to fit the 5/8" spark plug.

 

I cant tell 100% either.

 

the problem is that its rounded off..i went out and got these Grip Tite Scokets that supposedly are made for this kind of jobs, but still nothing. I even went to autozone for the hell of it and used Spike555 advice in buying the spark plug socket, but nothing seemse to work..I did every possible thing i can..I hammered it to loosen it up, i greased it, used a bunch of tools , but nothing


I bought these tools, but they didnt help

 

i'll give that Gator Grip a chance tomorrow and see how that works out

 

Wow man I wonder how that engine was even operable with only 3 plugs, I am amazed it even moved. Crazy!

 

Craftsman makes some sockets that have a spiral groove in them that will "grab" as you try and loosen. They worked pretty well for me. Try and use a breaker bar or long pipe if it grabs and use constant pressure.

I would PB Blast A LOT (let is soak in and repeat many times) or take a torch to it. Not much a little heat can't fix.

And by the looks of that picture, your engine needs a bath! Go to the car wash and power wash that thing to get all that oil off the valve covers so you can check for leaks.

Oh, and don't let your friends work on your truck!
