I'm supposed to get my broken plug pulled tomorrow by the indy down the road. He has a tool he got from Baum that another Indy swears has worked every time. The tool cost $400, thats a lot less then pulling the head. I'll post tomorrow night with the results. Wish me luck...

Did the glows on Sun. 1.5 hrs from shutdown to plugs done, we took our time buttoning it up and replacing all the high pressure fuel line guides/supports (clips and rubber, reused sturdy steel brackets). I HIGHLY recommend you do this BTW.

My brother removed the plugs with a 1/4" drive snap-on swivel-head ratchet - he has more patience than I AND has more experience with the 'feel' of certain fasteners.

Plugs #2-5 came out without a hitch, #1 and 6 were snug, so re ran the car without the intake to heat the engine back up. With a tad more elbow grease than was needed for the first 4, the last 2 were freed.

In the pic the plugs are in no particular order but the one most corroded is #1. Plugs were original, replace on the 27th at 102,200 miles

Excellent find and excellent article.

Those are Beru plugs, you can tell by the thicker/longer section of the nut.

May well have been OEM plugs at that tender mileage.

Congrats on a successful project.

*edit* in ref to post prior to above post.

You are being modest Jake; I don't think anyone has dealt with a broken GP with the ease and workmanlike manner that you did.

Ha! Thanks! But I think you give me too much credit. Ease? I cried myself to sleep the night it broke off!

As for workmanlike manner, well I was terrified of drilling into the head. I took my time and stopped frequently... like, neurotically... to make sure I was going in at the right angle. I even drilled & tapped a GP in my vice just to get a feel for it.

Just the same, there is NO WAY I would have even tried it if I hadn't found Alan's fantastic write-up. It laid it out step-by-step in a way I could understand, and made it seem like something a DIYer could do so long as they do it CAREFULLY. Hats off, Alan!

If it's helpful to anyone, I did these "crude" drawings to illustrate the process:

Excellent write up... Was very helpful....

I have 1995 E300, is the procedure much different than this? I will probably do it before winter. Thanks to lightman for the writeup!

Same engine..........identical procedure.

Matt L · #**164** 08-21-2008, 12:02 AM

Nearly identical. The pipe on top of the valve cover must be removed on the non-turbo 606.

Hey guys,
I followed the instructions to remove the glowplugs and now that I got to plug number 6, the threads cleared the block, but it will not pull out. I've sprayed it with PB Blaster to no avail. The threads are about 1/4 inch clear of the block, but the body is stuck in the chamber. Any ideas? Would cranking the engine blow it free?
