How do I remove a broken spark plug from a 2004 Toyota Tacoma?
What’s still stuck to the engine? Getting a glow plug from a diesel engine is not trivial (not that removing a spark plug is…) but glow plugs are smaller and you’ll either have to break down the engine and have the head sent out for a shop to remove that clump of metal from it or you’ll have to have a very steady hand to drill threads into the inside in order to create a base to secure a bolt head to unscrew the hole thing out. It is not a simple task.
The metal nut should still be intact. Just use a spark plug socket to unscrew it
Any auto store should have the tool or a spark plug socket https://www.grainger.com/product/1UBG1?g…!
