Suggestions?

While doing sparkplugs on the "new" car, I ran into a snag.

Two of the plugs broke off in the holes. Theyre not easy to get to.

I tried an EZ out, but again, theyre not easy to get to, plus it's an alum head.

I'll if I can some pics up.

It has it's advantages to have a 6'6" 290lb nephew.

He got them out with an easyout.

It still wasnt easy... ...

Since they don't make many straight sixes anymore I assume this is a V/6. Are both in the same head? You could try heating the remainder of the plug then hit it with some cold water, might break it loose but you are faced with water in the cylinder and if you end up having to pull the head and drill them out the heat/water may harden them causing that to be more difficult. They do make a Helicoil for spark plugs if the threads are too damaged to use. I have a 16mm tap if the threads just need cleaning. bg

Thanks BG, but my nephew got them out.

Yes, it's a 3. 3 nissan 60 degree V6. One was broke in the front, and one in the back.

Wow I've never seen that before. I would have bet that an ez out would never get them out. Hope ya thanked your nephew.

Must be something about those Nissan engines with aluminum heads. We have had a lot of trouble with the 4. 2L inline 6 used in the Komatsu forklifts. It is an excellent engine but the spark plugs they use in it have the threads stuck too far past the hole, exposing them into the cylinder. They rust and corrode, taking the threads with them as you remove the plug. I have had decent luck using PB Blaster and running it back and forth several times, backing it out a little further each time. I had good luck with a remover too, but mine was a Hanson brand, much stronger than a common "easy out".

i don't think i've seen that out of a ngk plug must be the rust, it's usually bosch that pop like that for me, as you found out a easyout is the fix with a healthy dose of penetrating lube, bet ya put antiseize on the new plugs :-laf

I put neverseize on everything I take apart.

I gave my nephew $100. His 2yo daughters B'day was coming up... . and I'm a pretty nice guy. :-laf He used it on her party.

I'm pretty sure I could have done it, but if it broke I'd never hear the end (the wife), so I figured I'd let him do it.

I gotta see if I can find the time to get a pic up of the removed parts. I've been on a 4 yr vacation, but I dont ever seem to have time.

I "kroiled" them for a few days before trying.

Aluminum heads and steel spark plugs... you NEED anti-sieze on the threads or you will have this problem again.



All of that heat in the combustion chamber tends to "weld" the two disimilar metals together.

I dont think if the previous owner took it literally "105K miles before the tune up" it wouldnt have been this much of a problem. :-laf

I'm a big neverseize believer though. :-laf

I see you used Kroil. I was going to suggest that but you were ahead of me. Why are the plugs so rusty externally?
I had that same thing hapopen to me with a 1972 Porsche 911 flat 6cyl. I about soiled my knickers when that happened. I took another plug apart and checked the fit of the easy-out I was going to use. This easy-out was my Grand dads, probably 60 years old and real chewed up. I torqued on that thing and just when I felt I was cranking too hard on it, it let go and the plug came out.

I cant say why they fused themselves there. Maybe they liked to wash the engine a lot, they are in a bit of a hole. It looked like it's gotten wet in there a number of times over the past 8 years.

After removing my injectors from the 12 valve, I ALWAYS blow off the engine after it gets wet. I dont "wash it" per-say, but if I happen to hit it by mistake.

 

[Dl5treez]

Sweet! Congrats to your nephew for getting them out. I pulled many-a-head back in my dealership days for this problem.



Kroil is awesome... . nuff said.

Man I have never ever seen such rusty plugs before it looked like they had been in there for a 100 years :-laf:-laf:-laf:-laf:-laf
