I am entirely unfamiliar with that stuff. So, I have nothing to add that would be based on knowledge. Jim

I am aware of what B100 is from reading about it - I meant I have no personal experience using it and have never seen any for sale, and have no idea what the fuel lines in my cars would have to "say" about that stuff given they are prone to speaking by leaking with regular Diesel. Yet. I am sure the day is coming when I will have an opportunity learn about it. There are others here with such experience with the OM606 engines.

I'm in luck (at least for a while)......

I tested my glow plugs and relay today... and relay is good and only one glow plug is bad....and it's the #1 plug.

Hooray. !!...I can get to it without pulling the intake manifold.

I really was dreading that job.

Ordered a couple of glow plugs today....

Now ...just hope it will come out with out too much hassle........???? and I won't have to take the manifold off.

Removing teh IM really isn't that difficult. Hardest part is geting enough extensions to get to the bolt holding the intercooler/EGR to the bottom of the IM.

You have much more control using your rachet with the IM off.

You should pre-treat it with penetrating oil each day for a few days prior to attempting to work on it.

Well, luck is running with me....but not all the way home.....

Got to the #1 plug with not much hassle without removing the IM.....but it would barely budge a little back and forth. Sprayed with PB blaster and tried again an hour later...no luck.

So sprayed it after every use...hot engine...for several days and tried again today....got it to turn....it complained and squeeked some...but gradually loosened....

So my luck ran short today......I've got the threads out but the plug won't come out. Since I haven't removed the IM...just the fuel lines going into the filter....access is pretty tight in there..have trouble getting thing on the plug.

I've sprayed it with PB Blaster a couple more times and given up for the night. Tomorrow AM I'll try one suggestion to try turning with the socket back and forth.....I've just been turning counterclockwise...

May have to take the IM off yet......

Do you have to access the 5mm Allen bolt from underneath the car??

If your Glow Plug has all of the threads showing; it must be trapped by carbon around the Electrode of the Plug (unless for some reason Carbon got past the tapered sealing edge and carboned up the body of the plug).
As far as I know no one has tried removing the Injector and spraying the PB Blaster on the GP Electrode inside of the Precombustion Chamber to soften up the Carbon and lube up the Electrode. You may be in a position where this would help.
Also you should ream or otherwise clean out the GP holes to clean out the Carbon; as well as a Never-Seez type compound on the GP threads
before putting in the New Plugs.

Anyone tried this ??

Sure is tempting to just spin it over a few times and see if the compression would blow that thing out of there......

There was a time when I would have considered that option untenable. Not anymore. I would definitely give that a shot, with a towel or something wrapped around it, before I continued to subject the thing to torque that might break the plug off. If soaking with penetrant doesn't loosen the plug noticeably, I would fire up the engine and see what happens.

People have done it and it works. One guy drove around for quite a while before it finally blew out. Obviously one should use extreme caution because it could shoot out like a bullet, but it sure beats having to remove the cylinder head to extract it.

I am "one guy who drove around" with a partially drilled-out #6 GP in my '99 E300 until it blew out. It took about 1000 miles and happened when my wife and son had the car a few hundred miles from home. You can read the whole story by searching my posts in the archive. It was repaired with a Time-sert by a shop in Costa Mesa; the threads in the head had been damaged by my local indy's drilling. He stopped when he realized he was off center.
In the case of your #1 plug, I think it might be a good thing to try. If I did this with a plug that was out past the threads like yours, I would place some kind of "diaper" to catch the plug to prevent damaging anything in the line of fire, and carry a new plug and tools to install it, and some Nevr-seez. Drive the car and listen for some sudden loud noises that would be very distressing if you didn't know what it was. According to my wife, you will definitely know when it happens.... Steve

Well, it wasn't necessary to "blow it out", although I'm kinda curious what might have happened.

Last night I gave the plug a liberal dousing with PB blaster and gave up for the evening. This AM I grabbed the end of the plug with some vice grips and then slid some long needle nose pliers just behind the tightening wheel of the vice grips and used a hammer on the side of the needle nose pliers. It came out with a few taps.

It was clear that the PB Blaster had done some work overnight. The plug was slimy and black along it's whole length. It was a Bosch plug so not the original.

I didn't have a reamer or any never-seize....and needed to get going today, so just put the new plug in and went on my way. I did start the engine and run it briefly to blow out whatever could come out.

Guess I could get the reamer and go through the process again.... but .....(sigh)...chances are...probably not ????? Even though I though I was lucky with the problem being the #1, and I didn't have to take the IM off...it was a PITA to get in there and I had to disconnect the three fuel lines from the fuel filter for better access. The car has 185K miles and I expect I'll probably need to do some others soon, so will order a reamer and be ready with the needed stuff and redo #1 at the same time.

All in all....I'm hugely relieved to just have the old plug out and new one in and nothing broken.
