Hi,

There are a few good threads on testing and working on glow plugs, but I haven't seen much on the best tools. I saw one thread where a drillbit was welded into an old glowplug...

But what is best practice? Just a drillbit? What size, should I get some sort of brush to work the holes like the site from up in Washington sells?

Is it smart to get grease in the prechambers, or am I better off maybe dipping the tool into oil which might have fewer ramifications?

Should I blow compressed air in or such vacuum on the hole before cranking to blow them out?

Thanks!
