I've got a 2014 1200 Renegade X with a spark plug that is broken off in the cylinder head. It broke right where the crush washer meets the body of the plug. There is still some of the porcelain inside the threaded part that is still in the cylinder head .If we use an easy out the porcelain part might end up inside the cylinder.

If the cylinder head has to come off, can it be done in the sled????? I'm thinking torquing the cylinder head bolts will be a real bear with the motor sitting on the bench.

Any body done a head removable on there sled ??

Look up Ford 5.4 spark plug removal. Been breaking them off for more than 10 years in them POS motors.
They're like porcelain recyclers.

You Can get the head off. With motor in sled. The hardest part is the valvecover removal.
But move youre stearing post Will make it a bit easyer.

If you look back a7 did his ported head build with engine in the sled just removing the head. It is also not that hard to torque the bolts with the motor on the bench.

Here's a thought, kinda shade tree, ******* engineering, McGivering, call it what you will, Does anyone think its possible to avoid removing the head by using a shop vac to get what ever porcelain, metal etc that may fall into the cylinder during plug removal. Never heard back of anyone trying it. I would think taking a peek inside the cylinder with a borescope would be in order before feeling comfy nothing was left in the cylinder

is it possible to roll it over to make sure that piston is at the top use an easy out if possible and do what killer said,,use the vac to suck out debris

Not sure if I would want to bring the piston to the top. The plug is broke off at the crush ring there may already be porcelain and the electrode laying on top of the piston. Gotta leave some room for the tip if the easy out too.

i wouldnt take the chance of risking a piece being left behind by doing it on the motor

but seeing you are in ontario if you need the cam and crank locking tools to borrow i have them

Any seasoned Ford tech can definitely help you. Any porcelain left behind in the cylinder will blow out when you crank it over without the spark plug in it. The porcelain won't hurt a thing. You would need the Ford tool to get the left over spark plug out though. Do you have tons of miles on this sled. Normally these plugs are good for 15 or 20 k.

I've removed many broken Ford spark plugs. Unfortunately, the Ford tool won't be much help in this case as the threaded part of the plug is still in the head. But the initial approach to deal with the porcelain would be similar. Use a punch to drive the porcelain downwards until you have room to bite into the plug with an easy out. The ground strap in the plug should bend but hold the porcelain from dropping into the cylinder. Cut the easy out so it isn't any longer than it has to be. Maybe cut an old spark plug at the break point to allow you to size up your easy out on the bench. Make sure you get the centre electrode out if it drops into the cylinder, small pieces of porcelain I would not be so worried about. A shop vac adapted down to a small hose could be used to suck out any debris. Check with a bore scope. Fire it up first with he plug out. Good luck.

Killer-Beez doesn't have a bad idea....

You could also take a fitting from a compression gauge and see if I could take some tubing and seal one end to the fitting and the other end to the shop vac to create as tight a vacuum as possible after your are done to get any small particles sucked out of there. Then I would use the scope to check for debris.

OK , thanks for the different tips, these plugs are small in diameter so I'm not sure a bore scope would fit through the opening.

How did the spark plug break off? That's not a common occurrence with the 1200, or so it seems.

Lot's miles between changes?

Just curious.
