Maybe I should have been more specific, but I was comparing the modulars to other aluminum-head motors. Not iron-head production slugs
GM doesn't have a problem. Dodge, Toyota, Honda and the list goes on, don't have problems. The new V-10 doesn't shoot out plugs either. Sounds like VW and 2v V-10 are related somehow.

I was comparing the modulars to every ford small block v8 from 1962 until 1996/97. That's 35 years of trouble free spark plugs. What's the modular on now, 13 years(with some limited production starting in 91)? 9 years that couldn't keep the plugs in and 4 years you can't get the plugs out?
They haven't been production, but I've owned several aluminum headed mustangs and have yet to blow a plug out of them. The other brands haven't had any problems with their aluminum heads either. So it must not be the aluminum that's causing the problem. It's probably the combination of the aluminum and the lack of threads. Or in other words, a design flaw
But that is in the past. Now we move on to newer smog laws and restrictions. Yippee

Using the logic of previous posters in this thread, there would be no spark plug insert kits available if there wasn't a problem.
I was using a VW tech's experiences as an example of how other manufacturers also have spark plug problems. They do exist.

Thread inserts were developed a long time ago and are also used in cast iron heads. Sometimes mechanics screw up and cause problems like this. Thread inserts or helicoil's are used in many areas not just on spark plug holes.
This is pretty funny how the factory heads blowing sparkplugs and people stripping or cross threading bolts or sparkplugs are the same issue. I don't know.............
EDIT: I have not heard of any other motor launching sparkplugs except for VW which I just learned today.LOL

Like it was mentioned, blowing plugs is not a characteristic of aluminum heads, its a characteristic of poorly designed aluminum heads.
Virtually every small engine since the mid 50s has had aluminum heads, and I don't hear about them blowing sparkplugs out. I've seen lawnmowers with less-then-finger-tight sparkplugs still running happily and no sign of the threads being stripped out. All of the new fancy OHV V-Twin small engines running 9:1 compression don't eject plugs. I don't see tons of dirt-bikes, four wheelers and motor cycles shooting plugs either. My Honda XR200 has about 12 "threads" on both the plug and the head to hold it in, the original 2 valves had what? 4-5?

No one is saying that no other car on the road besides the triton has ever blown a plug. Sometimes people who should never even open the hood of their vehicle try to change plugs and cross thread them, don't tighten them good enough, etc, and they blow a plug. I said the modular is just MORE PRONE to shooting plugs and that even factory trained technicians have problems getting the plugs in correctly(if the plug shooting is caused by improper installation). Go to the modular forum and look up blown spark plugs and see what you get. Dozens of threads with hundreds of people complaining about it happening to them. Go to yahoo and a search for blown plugs. 9 out of 10 sites that come up are about the modular. Consumer affairs has over 300 pages of people saying it happened to them. You can search the entire forum here and you won't find as many blown plugs in every group combined as you'll fine in ONE thread in the modular forum alone.
In the 4.6/5.4 section someone posted a poll wanting to know how many have had a plug blow out. 52 of the 159(32%) people responding said they have had it happen, and that was just 4.6 and 5.4 owners and didn't count multiple blown plugs. That's a very high percentage for that many of voters. Some of those people have had 3 or 4 plugs shoot out on the same engine. It's not something that's going to happen to every single engine or anything, but it is something that happens at a much higher frequency than on other engines.

The same can be said about the 6.0L and head gaskets,yet the diesel guys all argue that it's not a problem,and it's isolated to certain years,etc.
