Replacement of Swollen Glow Plugs
Hi Guys,
Well I lent my truck to someone who did not know about the starting procedure and turned on and off the ignition switch over and over again. The truck will not start unless I shoot a little ether into the stack. I ordered a new type controller and plugs. The question is that I have heard that it is hard to remove the swollen plugs.
Is there a secret to it and what should I look for or do?
Thanks,

replacemant of swollen glow plugs
They can fail and not be swollen and removing swollen ones with a home made thread extender is really easy so don't get worried.

Allan,
I had a mechanic do exactly the same thing to my truck.
I my case all the plugs failed.
The mode of failure was 4 unswollen, 1 swollen but intact and 3 swollen and ruptured. The ruptured ones had dropped the head of the glow plugs in the prechamber and I had to get the bits out using a magnet!!!
I would not suggest driving the truck until you have determined the state of the plugs and retrieved any debris that may be inside the combustion chamber....
The diesl is high compression so there's not a lot of room in there and a bent valve is a possible outcome of fragments in the cylinder
You probably don't have ruptured plugs, but I thought I'd share my experience
Cheers

glowplug
hello
i did this with two marine powered 6.2 l v8 diesels
all plugs were muchroom'd and blown
if it is a side chamber diesel try this
it is not so difficult
take the diesel injecters out
look in the hole and you can see the exploded piece
try to screw the plugs out till they stuck
the plug is as a muchroom exploded the tread wil come out
take a pipewrench and braek the plug off
the little piece inside the engine can not fall on top off the piston
you can take that out with a magnet through the injecter hole
greetings george

If you HAVE started the engine after this and there WAS debris... then you can count on the piston being just that much taller now as the "debris" is now part of the piston which can cause other problems... such as creating a "hot" spot on the piston face which can cause piston failure....dunsbr wrote:I would not suggest driving the truck until you have determined the state of the plugs and retrieved any debris that may be inside the combustion chamber....

Guys I have found the ultimate glow plug removal tool you do not even have to remove the heat shield. I removed seven badly swolen plugs today in the matter of 2.5 hours. I will be offering the tool from my website. This is not a tool I manufacture but It is a must have if you do your own maintinance. The price I believe is around 75.00 but is well worth the time and frustration saved. I bought the tool about 8 months ago and never used it until today. I was very happy with results. I will Hopefully have them availiable by Monday. This thing is cool! simple and easy to use.

I think that it is time for me to purchase such a tool as at least one of my plugs is swollen and will not come out.
Please tell me more about the tool.
Thank you,

Hi Pat,
Here's a link to a pic of the tool at shawn's site:
http://www.angryironoffroadgear.com/Puller_Assy.jpg
and heres the page with the ordering info:
http://www.angryironoffroadgear.com/garage_gadgets.htm
I have one of these tools and they work a treat.
It's almost as easy to pull a swollen plug as normal plug!
I got mine from Steve K at Owens Export 4 years ago/
Cheers

Pat,
Here's a picture of the plug removal tool I got from Steve at Owens Export in LA. It's the same tool as Shawns but is in it's basic stainless finish. It'll go out to you this week.
The plug is from a 1009 instead of a HMMWV but you get the idea how it fits into the tool.
You hold the smaller hex section with a wrench and then back out the larger one and it draws the swollen plug out with it as it comes. If you lose a section of the plug you will have to remove the injector and fish around inside to recover the broken bits.
If that doesn't work then the head needs to come off. Hopefully anything left in the cylinder either blew out or didn't imbed itself in the top of the piston.
Good luck
