Spark Plug Sank
Hi all,
Tonight, I was changing my spark plugs.
I managed to change 5 out of the 6, but the rear middle one looks like it "sank" into the engine, and I cannot cover it with the spark plug socket in order to twist it to take it out.
Did anyone experience this kind of issue before?
Thanks

Never had that happen to me. With a mirror, look down into the spark plug hole and see if something is keeping the socket from going onto the plug. A plug cannot sink into the head unless your head was ruined.

That's the thing - the metal part that the spark plug socket should connect to is too low to reach.
Actually, the spark plug itself is too low to reach.
Just to mention - car runs fine with no issues/check engine light on.

I can’t imagine that what you’ve described can actually happen.
If the plug has physically somehow displaced lower into the combustion chamber I’d imagine that there’d be piston to electrode collision, terrible noise and engine damage.
I think more likely what’s happening is that something has either broken off (coil boot), shifted (valve cover gasket O) or fallen into (debris) the plug recess.
If you haven’t, try to get a visual as has been suggested.
Honestly, you might not have an issue at all. Be patient and be sure that the angle at which you’re meeting the plug with the socket is correct. The space in the plug hole is tight and the angle has to be correct. Be patient and spend some time finessing the socket down over the plug.
