Hello, I’m looking for a compression tester with a suitable light plug adapter for the Opel 170PS 2.0 CDTI / B20DTH engine. The light plug has M10x1 with a total of 171mm length, or X2= 95mm. I don’t find any tester with a suitable adapter. Should be possible in a private user compatible price range up to max. 150€, actually rather less parts but with quality instead of full equipment f. 20€ and then broken with the first use. LG Eddie
