      Great tool worth every penny.

      I was very worried I would need to dismantle my engine and be faced with a costly machining bill but then I saw the thread chaser on ebay and decided to give it a go. The chaser worked excellently and it was also very easy to use. so for a small outlay and a few minutes of time it saved me a lot of money and stress.

      Snapped in head.

      This tool snapped in the head, so I’m left with a much harder job to fix the thread now. Should’ve just helicoiled it in the first place, but thought this would save me time. I was really wrong. I suspect the bottom of the thread beyond the spark plug had some carbon build up and so it’s not so easy to engage and reverse out as stated. Having said all that, this sealey tool is better quality than the cheaper versions on eBay that don’t close up when the plunger is screwed out, so at least it can be inserted into the combustion chamber. All in all, I would not recommend this tool. Helicoil is the correct way to fix a cross threaded spark plug.

      Good tool, but very delicate

      I’m a mechanic by trade and had a few Rover V8 engines that have alloy heads, two of which had some stripped threads for the spark plugs. I saw these on EBay and thought I would give it a go, what I did notice is how the price varies for the tool, you can find them between £14 to £40!! All Sealey branded. The first one I brought did the job ok, but remember it is a cheap tool, halfway on recutting the thread it started to struggle and upon removing it I saw that one of the threaded legs had slightly twisted which meant the remaining threaded legs would not align with the other threads, there seems to be quite a bit of flex in the tool, probably poor quality steel? Despite this, the spark plug went in and all was well, but the tool was now useless. A few months ago I had to do another ...

      A useful, well-made tool!

      This is a useful product and works well. It can be used without any fear that any swarf or dirt from the plug threads will fall into the combustion chamber. When this tool is used the waste matter is drawn out as the tool is wound out of the plug hole. It just about pays for itself in that you save on the cost of a new cylinder head gasket which would be needed if you removed the head to use a tap or similar thread chaser to clean up or repair the threads. I used it on a Stuart Turner marine two-stroke and it fixed the problem of the plugs not screwing up properly. All you need is a small adjustable spanner with which to wind out the tool.

      Reverse Actio Spark Plug Threas Chaser

      The starting thread for the spark plug on the alloy cylinder head had become difficult to start when fitting the spark pug. Watched several youtube videos on using the tool. It worked well and quickly "trued" the thread and the spark plug easily fitted. Very pleased with the result.
