yes it's a serious question. I was hoping for some more concrete reasons than those listed.

my wiring harness has 230k on it with out any issues
and not all HGs fail at the #6 cylinder.
Blame the EGR if you want but I'd more likely blame the dead spot in the temp gauge and an engine running for long periods of time at an elevated temp without the driver realizing it.
This happened to me this spring. I was running down to NC for a trip and my modded gauge was running a little warm in the mountains. Turns out that the radiator was shot. When I am saying warm it was probably around 210*. well within the dead zone of the stock gauge. With the stock gauge things would have needed to get a lot worse before I would have been made aware of it.
Justify this mod any way you want but selling it as a HG or harness deterrent to failure seems like a stretch to me.
You know better than that, Rick. A vast majority we've seen on this forum fail at that spot.not all HGs fail at the #6 cylinder.
From prior discussions on the board, it seems that head gasket failure is not nearly as common in Australia, where they have no EGR. The fact that the failure most often occurs at #6 and the location of the EGR is simply a coincidence to you, I take it?Blame the EGR if you want but I'd more likely blame the dead spot in the temp gauge and an engine running for long periods of time at an elevated temp without the driver realizing it.
IdahoDoug's rigs and many other have failed with meticulous maintenance. While I'm sure overheating will accelerate HG failure, I'm not convinced that every case, or even most cases, are due to this.This happened to me this spring.

Personally, I don't find the harness or especially the HG deterrent to be a stretch at all.Justify this mod any way you want but selling it as a HG or harness deterrent to failure seems like a stretch to me.
most everyone who has replaced their HG has also left their EGR system in place and haven't had another problem. It would seem to me if the demon EGR was the culprit of HG failures it would continue to do so.
I tore down a 1994 engine with 280k on it and the original HG was in perfect shape. So what does that tell you?

I suppose you have to wait another 10 years or so to see if the same engines blow HG in the same spot
Rick is just annoyed because HE didn't come up with this idea in the first place, is my guess and now he is going to argue for the sake of arguing.
Basically if you take the terminals out of the connectors, and hold them side by side, you will see what I'm talking about.
Pics will come when I get my truck back from getting the new exhaust.
Don't need a blockoff plate. The JB weld will do the trick.
then simply leave all the parts in place and and disable them by taking the vacuum lines off and cap off the ports on the throttle body.
no pics....just pull the 2 lines off the TB that go to the modulator and cap off the nipples on the TB...thats it..or you could loop a 3" line from one nipple to the other like I did essentially capping them off.
The egr system recieves it vacuum from these 2 ports on the TB so you have disabled the system by doing this and the egr valve can no longer recieve any vacuum required to open it..
you can leave everything in place if you want..even all the lines its up to you...
of course you will be getting that dreaded CEL shortly after doing this....thats where the resistor mod or something to trick the ECM comes into play..
