It's off to go to the machine shop that the local dealers send them to. It is my understanding that if they break, it is just above the threads due to the 2+" long annular space between the seating surface and the threads filling with hard-pack carbon.
Additionally, the reamers do not remove carbon in that area, just where the glow tip goes in the prechamber. You need a long 11mm diameter wire brush to get the carbon out of where the body of the plug goes... PB blaster does a good job of loosening the carbon so the brush can work. -- John W Reames jream...@verizon.net Home: +14106646986 Mobile: +14437915905 > On Jun 26, 2014, at 17:25, Meade Dillon <dillonm...@gmail.com> wrote: > > Are you taking the head to a machine shop? > > Did the plugs break leaving threads in the head, or did the threaded parts > of the plugs come out? > > Max Dillon, > Charleston SC >> On Jun 26, 2014 3:03 PM, "John Reames" <jwrea...@comcast.net> wrote: >> >> I have not changed them before in this car; I put over 80k on it highway >> driving, and since then it has been a mix of city and highway. >> >> Disabling EGR in a turbo is a little more complicated, and I haven't >> messed with it. >> >> I believe that anti-sieze on the bodies of the plugs is likely the second >> best way to prevent break-offs. >> >> The best way would to have a head and glow plugs where the threads were >> closer to the seating surface... >> >> Mercedes sells an expensive tool set to deal with the plugs, but it's a >> combination of pichler 6041760+60419050+6049031... >> >> Good luck in getting prices! >> >> -- >> John W Reames >> jream...@verizon.net >> Home: +14106646986 >> Mobile: +14437915905 >> >>> On Jun 26, 2014, at 12:32, Meade Dillon <dillonm...@gmail.com> wrote: >>> >>> John, >>> >>> Is this car mostly driven in the city? >>> >>> Is the EGR still working? >>> >>> I'm wondering if measures can be taken to reduce carbon buddy build-up, >>> reducing the risk of glow plugs breaking off. >>> >>> Max Dillon, >>> Charleston SC >>> _______________________________________ >>> http://www.okiebenz.com >>> >>> To search list archives http://www.okiebenz.com/archive/ >>> >>> To Unsubscribe or change delivery options go to: >>> http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com >>> >>> All posts are the result of individual contributors and as such, those >> individuals are responsible for the content of the post.
