Spark plug wire tool?
Posted: Mon Dec 07, 2020 9:45 pm
Has anyone come across a good tool for removing the spark plug wire retention 19mm nuts on the spark plugs?
The right size crow's foot wrench may work, but things are pretty tight (very few degrees of swing) in between the valve covers. They make special sockets for oxygen sensors that have slots on the sides -- that's the kind of thing I'm looking for. Or even better, something like the tool used for lawn sprinkler insert removal.
Yes, of course I could fabricate a tool, but I first want to see if there's one off-the-shelf. I've looked quite a bit, and not found anything.
I was able to remove mine, but just barely by using a collection of different wrenches that had slightly different angles. And even then, the plugs came loose before the wire-to-plug nut did, so that added a few complications. I'm simply looking for a better solution, and an excuse to buy a new tool.
PS: Please don't drag this off-topic on why one should just convert to non-OEM plugs and wires. That's another thread...and as one who owns and works on aircraft engines that use the same wire and plug system, you're unlikely to convert me.
