Hi im interested in learning to ream out the gp hole.
Dont mean to sound nasty but thats what id like to learn to do.
Also does anybody recommend any particular type or brand of reamer out there?
I have seen so far Mb brand and a kit form mercedes source with a little brush etc.

Winter will be here, i plan on removing testing and cleaning rather than just replacing gp's , just to be thrifty at this moment.
If i can learn to clean out carbon deposits as much as possible that may be a good way to save, normally i just do all new glow plugs but that can get expensive, especially since my parts supplier has risen prices at least 30%, according to them the dollar is in such devauation and the euro has not so our parts are now worth so much more.
