Idiomaticman,

Now that you have read the responses above, you will understand why I didn't post what I am about to say previously.

I have a life long friend who has worked on diesels for about 30 years. he runs the county shop now with over 1000 vehicles, heavy machines, stationary engines for gen-sets and so forth under his care.

We were talking about glow plugs a while back and he said that it is common for them to expand on the end when they have been left in service for too long. It isn't just a brand issue. (Here is the part that I hesitated to post before) according to him, it is common practice to drive the broken piece down into the cylinder and leave it there. He said that it gets pounded into the top of the piston where it lives for the rest of the million miles or so some of the big engines go. he said that he has never seen a problem arise from doing this. Keep in mind that Power strokes are just one of many types of diesels that he has had experience with, so I couldn't say how often he has seen this or done this with a Power stroke or 444.

Like others here I cringed at the thought of it, so I'm just passing it along, not endorsing it.

I need to replace my own glow plugs. If one breaks off, I don't know if I would do it or not but it sure seems counterintuitive. Let us know if anything develops.

Incredible!! How can the steel glow plug tip mashed into the aluminum piston not create a hot spot? I would think that at the very least it would cause premature piston failure.

I guess if it works it works, but I still don't think I will try it if the situation arises.

I have the Berus in stock, just haven't installed them yet.

They have them at Autozone in Motorcraft packaging for anyone who is looking for them.
