I've got a gunston compression tester but will not screw into the plug hole on a Zetec, it appears that the Zetec plugs are a deep seated type where the thread doesn't start at the top of the hole so thread on tester is to short, any ideas or do I need to buy another tester specific for a Zetec"
Loads of places online like ebay and amazon to name a couple
