Glow plug breakage

If a compression test has been performed, then the pistons have travelled their full upward, toward the head, ie TDC.
Since there is very little clearance between piston and head on a diesel, any foreign objects will be either broken or imbedded into piston crown or cylinder head. If only small bits, it may exit through the exhaust valves if it has been started. Only way to see, is to remove the injector and inspect the piston with a small dia bore scope. ie, digital image device. That won't tell you if the valves have been damaged and if the rubbish/broken piece isn't there it could have bent one of the valves, and it is that which is not sealing on it's seat and causing compression loss. If so it is head OFF to repair it all.

A few years ago I had to diagnose the a John Deere tractor. An object had entered through the inlet valve, a mechanics fault, and broke the nozzle of the injector. Only dribble was injected and no spray of diesel, causing a misfire every time and on a couple of other cylinders because of it being a rotary pump.
If a dealer is repairing it, they may only do the minimum to make it seem ok, so be careful.

To me, it has to have the head off and make sure all components are serviceable and fit for duty.
If it was OK beforehand, then the compression test man has allowed something to enter the cylinder.

Sometimes the offending piece of material gets stuck between an exhaust valve and it's seat and simply stays there.
The dealer should know if one of the glow plug ends is missing when they removed it. That will not come out through the glow plug hole and might be able to be removed through the injector hole, if not then head off.

If the mechanic is at fault he will be covered by insurance for accidents like this and getting a proper appraisal and repair (if required) should be no problem at all.
Speaking from experience from 40 years ago when the wing nut from the air cleaner fell off and went into the engine of a 6 cylinder Cortina we had during a dyno tune (at red line RPM). It bent a valve, punched a hole in the piston and cracked the block. The motor was completely rebuilt to new condition.

I'd be walking away from this one.. its likely the head will need to come off.

Now we find it is a V8 LC and anything dropped into the cylinder will fall to one side if gravity is working in that area. So, the item will be at one side. I would like to know how they are going to get it out from over one side. If a 6 cylinder it would be simpler because the piston will be horizontal.
Because it is a V8, the dealer WILL NOT BE WANTING to remove the cylinder head at all costs, mainly due to costs.

A refund might be a prudent decision as above.

The breakage points to a larger problem, does this 1hz have a turbo? If it does, walk away, it has had lots of heat errode that glow plug, and thats not good. It will have been starting on 5 cylinders for a while, unless its cheap enough to factor in a rebuild, at least you know why its been traded

VDJ engine doesn't have glow plugs.

Are you sure anything actually fell into the cylinder, or did the compression tool just snap off in the head?

Attached is the report (that has been like pulling teeth to get)

Firstly nil information on the methods used to remove the broken tip.

But more importantly blaming it as already broken prior to removal - what could cause the tip of a glow plug to be broken?

Thanks for coming along on this journey!

It's quite simple...
Don't Walk, Run..and don't look back because with a dealer attitude like this...they will throw you under the bus the first opportunity they get..
Keep your hard earned in the pocket, for there will be a few 200 Landcruisers floating around as owners will be looking to purchase a 300..(why? I do not know)..

Took the high road and politely put my views forward by email this morning - basically radio silence since from the same dealer who text 3 times to see if I had received an email yesterday afternoon.

An off topic question but being a GLX model it was registered for 8 seats, but has drawers in the back currently. Nothing has ever been mentioned about the rear seats being supplied. If they have been silly enough to change the registration from QLD to NSW without getting a modification certificate would this make the safety certificate invalid? Out of interest would that have become a possible issue if I'd try to sell the vehicle down the line and not had the seats? (Yes I know I could buy them but in theory)

Finally reached a resolution and getting the deposit returned. Thanks for the advice given - avoid a 2010 LandCruiser GLX being sold in Tweed Heads at the Toyota dealer! ??

The search continues!??
