Thanks for the leak warning Tom...I will wrap the soldered line and wear safety goggles & gloves....Greetings from Mississippi USA....Are you reading the glowplugs unconnected from the relay ? Have you tried another glowplug in #3 ?... My friend here owns a diesel injection shop..he says after the elements are set it is best to leave them where they were set at the factory....You might try adjusting the valves again on #3...How are you reading the glow plugs ? what kind of meter ? Your English is much better than my German.....kevin
