If you are going down the route of a compression test try to get an adapter to fit to the glow plug hole(s)


Take out all of the glow plugs rather than the injectors and save yourself the cost of new heat shields that are fit only once items.


It is unlikely the cheapest compression tester kits come with the correct fitting for the glow plugs but most leak down tester kits do...
