Aerokroil penetrant works well too, much better than pb blaster

Hey all! 98 e309td here. Was able to get out all my glow plugs except #4.

It turns a little, so be spraying PB Blaster on it every few minutes and tapping it to set up a vibration to hope fully get that stuff down in there.

Well, it finally started turning, although very hard.

Now, the corners are rounded and the socket just spins on it.

I thought of trying to get vice grips in it but it's hard to get in there.

Then I thought of sacrificing a socket by filling it with JB Weld and pushing it over the glowplug, letting it dry and then trying to turn it.

Could use some advice.

Can y'all chime in with suggestions?

Thanks!

Did you mark the glow plug to be sure that it was actually turning? If not I'm going to assume that rather than it turning, the nut was simply rounding off. Gluing to it is probably your only chance at twisting it out. Most likely it will twist off and then you can go about pulling the remainder of the electrode and drilling the plug out.

Yes it was actually turning. I rounded it off after a few quarter turn mostly for the same reason most bolts round off, I didn't have the socket on well enough. My fault and now I get to pay the penalty

I vote for the JB Weld, but first be sure to clean the plug so the epoxy can stick well.

Well, that looks like the plan. That "deep well" Gator Grip I bought won't bite because the nipple on the plug is too long. So, gonna try my method tomorrow after work.

Already sanded the plug and the inside of the socket with 60 grit and wiped em good to give the JB something to stick to.

Running the engine to heat it up was great thinking and it turned a little until the socket slipped again so we will see tomorrow.

Maybe try lining the socket with foil before loading with JB, like one of the suggestions before loading that socket up with JB...😀

No, either JB Weld or foil, don't try to mix them.

There is a special socket available specifically for 606 GP's. It's not too spendy and totally worth it. It has a swivel, and extension, and a captive socket all in one. I've done it both ways, and it's a big improvement faster and easier with the special socket. Not sure if our host stocks it, but samstag and baum do. It looks something like this:

Lol, I wasn't planning on doing both at the same time

One problem I recently encountered with 606 gp change is the plastic electrical connectors. They become brittle and break when removing them, and then no longer securely snap onto the new glow plugs.

Thankfully, the plastic portion of this connector is its own part and is easy to replace. Mercedes part number 019-545-54-28 available from Pelican. Current pricing is $2.50 each, very reasonable. I just replaced all of mine. Once you have the new ones in hand, you'll get how they work. It's two pieces that snap together, easy.

Hello everyone. I have been reading the forums on changing the GP and just want to say thanks for all the great advice. Last night I took out all my GP successfully. I guess I got lucky. Only #1 and #5 put up a bit of a fight but nothing serious. I did it with the engine very hot. When it was time to take the IM off I had to use gloves to handle it. I think the hot engine was key in getting the GP out in one piece.
Also my car only has 117k miles and I have no service record of anyone changing them before. The plugs that came out were original Beru.

Today I will clean the IM and put everything back. I see people give two different torque values for the GP 20NM and 27NM. Which one is the correct torque spec for the GP?
