Glow Plug Delete Pic

[JD Dave]

Got these today from DPR. What should I use on the threads for install?

 

[jdlover1]

I would use anti-seize or spray penetrating oil on them.

 

[emiller3]

Does it really need any thing on the treads?Would it hurt to leave them dry?

 

[JD Dave]

My thoughts were copper antiseize.

 

[SIKDMAX]

Nice piece.

 

[bullfrogjohnson]

Definitely use copper anti seize. It will definitely save you some headaches in the long run. I use copper anti seize on all bolts that go through a bunch of heat cycles.

x3 on the copper anti seize I put on my glow plugs don't want one breaking off in there

 

[JD Dave]

Thanks guys, copper anti seize it is.

 

[bullfrogjohnson]

also put it on your exhaust manifold bolts, up pipe bolts and all the turbo to pedistal bolts

where can i get them?

Use some sort of anti seize or ARP moly.


Your going to want to pull them out in put the glow plugs back in. Trust Me.:thumb:

Why do you say that John? I've been having problems with my glow plug controller and was thinking about getting rid of the whole setup as I have gotten used to plugging it in when its cold out, but if there's a good reason I might have to figure out the problem.

I ran no glow plugs all last year, but my crank broke before it got too cold, i think at scheids it got down to the 50s early in the morning, i might have had a upper 40s start but thats about it. It always started fine, but i can imagine it wouldnt have if it got much colder.

I don't get it why is there a tip on it

I wondered that also. I thought they would just be a plug.

I would say to block off the area in the head so combustion heat could not travel up the empty hole and erode away at the ledge where the tip used to be. Just a guess though.

My truck starts OK with out the glow plugs down to about 50. Below that it gets cranky. Using the glow plugs cures that. Even on warmer days the glow plugs help smooth out the idle right after starting. Plugging is great if you can. My truck is track/trailer queen. I tow it to pulls sometimes a days drive away. So I would need lots of extension cords to keep it plugged in. It has been as cold as in the 30s and with the glow plugs it fires right up.

I know that even a small change in a duramax combustion chamber can effect compression ratio.

I don't know if this is the reason why or not but it seems to make sense that if you remove the tip from the "dummy" glowplug, you could end up lowering your compression a little. Combine a little lower compression with no glow plug and you just made starting that much harder. Keeping a tip on the "dummy" plug will keep you from affecting your CR. Since it does not heat up, there shouldn't be any issue of it breaking off inside the chamber...

Again, this is speculation. DPR would be the best source for the answer.

Is that basically a grade 8 bolt turned in a lathe??
