Swollen glow plug tip

For those who have never seen what a swollen glow plug tip looks like. Here is an example. These 2 came out of the passenger's side of my truck. They were supposed to have been changed in 2004 just before I bought the truck. The swollen one is an 11g, the non-swollen one is a 12g, the 2 others that I removed weren't swollen and they were both different brands, AC Delco, but I couldn't find anywhere that said what "g" they were.

Moral of the story. Don't ever trust what you've been told. The only way you will know for sure what is going on in your truck is to inspect it for yourself. If you're going to go through the trouble of getting at the passenger's side glow plugs, you might as well replace them. Afterall, it's only about $65 for a set of 8.

The pic of the 2 plugs is the other 2 from the passengers side. I can't see anywhere what "g" they are. They are AC Delco 771 107. The pic of the 4 plugs are from the driver's side. They are all the same, AC Delco 11g.

I hope you don't mind me adding this Dave.

This is what you don't want to see when you change your glow plugs, lol.

If this pic doesn't work you can see it in my garage.

I don't mind at all....and you're right. I think I would $hit my pants if I pulled that out. I was starting to pucker a little when the one with the swollen tip didn't slide right out.

The last time I changed glows, the 9 g's were mushroomed to about twice that size and one broke off in the head requiring the injector to be removed to blow it out with compressed air.

I was able to jiggle and finesse that one out. Any more swelling and I think I would have been screwed!

Removing GP tip with compressed air

quantum mechanic The last time I changed glows, the 9 g's were mushroomed to about twice that size and one broke off in the head requiring the injector to be removed to blow it out with compressed air.

To blow the tip out with compressed air would you bring the piston to TDC for that cylinder and use a special air nozzle or what?
