Glowplug tip burnt off.....now what

[Profister]

I have the same experience with Hyundai glow plugs as everyone else in this thread. I got them installed at CVI in October 2011 and as the mornings are getting cooler this fall I realized that it was time to replace them again. I went with NGK CY55's for the same price as Hyundai ones this time.

OUCH!

I hope your heads are ok!

You have run your delica under abnormal glow plug relay system for a long time as power continuously went into glow plug.
This one could happen to all kind of glow plugs when your glow plug relay has failed , but you tried to start the van in certain period without fixing.

I only replace with NGK plugs. Butch at CVI worked on my L400 last week and two of my plugs needed to be replaced (note: this cured rough starts, which makes sense). Butch specifically called me to confirm that I was okay paying extra for the NGK, which he recommended.

For all 4 to be burnt off like that, definitely something wrong with the system. Once in a while, a tip may burn off, but for all 4, I suspect your relay stuck on at one point, or the ecu is starting to malfunction causing them to stay on too long. If one tip was burnt off, and a couple others burnt out, I would say could be because of cheap plugs. All 4 burnt off= system problem. Or you had some wickedly hot burning fuel.

Relays don't get "stuck on." There needs to be power to a relay to move the armature and close the circuit. Without power the armature will spring back.

[Manitoba deli]

Relay's do stick on, when they get older, and the contacts get dirtier, when they are activated by the signal voltage, arcing can occur between the main contacts, essentially welding them together, keeping the voltage flowing. If your lucky, when it gets hot enough, the contacts will let go. If your not so lucky, the relay eventually gets so hot it catches fire. Either way, relays can and do stick on. If you are changing your glowplug relay, make sure you replace it with one that can handle the amperage draw of the glow plugs. Minimum of 60amps. 80amps would be better.

What? Where did you get this from? It looks like you are talking about someone else; I have never had any problems like that.
The reason for my post was to confirm what the OP and other drivers were telling about Hyundai glow plugs floating around. That's it. Somehow I am the only one to blame on doing something wrong.

I checked my system by Installing a light so I know when they are on and when they turn off and everything seems good and never had any other glow plug tips burn off before..... I just had the one tip burn off but the others were not far off.

my suggestion would be to check them out to see any signs of wear if you have these plugs just to be safe

Here is how 10-month old Hyundai glow plugs look like. Installed at CVI in October 2011, replaced by myself with NGK CY55 for the same price and no labor cost. Do your math.

Hi,
I am forced to express my thought.

1. Profister has been well known for anti RSI and Hyundai part for a long time in this forum.
It is very strange he has used Hyundai parts, so I strongly suspect all claims are artificially fabricated to harm our business as usual.
And I noticed all happenings has occurred in enemy’s camp, not in neutral zone.
Glow plugs were replaced by CVI at 2011, and replaced again by himself this time, so you got any witness?

2. As Manitobadeli noted, all 4 glows plugs can’t be burnt off at the same time if your glow plug control system is in good working order.

So Here’s my suggetstion.
1. Take those glow plugs to CVI and ask for Butch’s opinion.
Ask if CVI checked your control system a few times before installation under cold weather to figure out what was wrong at that time.
Butch has installed too many Hyundai glow plugs for his customers, so I am very nervous of his installation pattern/practice.

He gave power to glow plugs continuously without self control due to some other reason.
so, could be a control system problem.Steven

You have no idea what you are talking about as usual. All systems in my L400 work top notch including a glow plug one. Speculations like yours do not contribute to this thread. Stop it. I am done here.

2. Check your engine by opening the cylinder head for damages.
I do not believe your L400 is in top notch status as your engine has eaten up numerous debris since 2011.
If you claim no damage at all after inspection, this will be a strong evidence you has fabricated all claims here.
If this case is a fake , pls stop and get out of here.
Remember lots of delica owners here have Hyundai glow plugs installed ( over 300 ), and they are very stressed from your claim.

3. If Butch says everything was okay, take this case to Hyundai Motors.
You will get a call from their technician and lawyer. Who knows you get a compensation from Hyundai Motors?
You will get paid what you have done.

Steven

I would stay away from suggesting that anyone is fabricating information. State your case and leave personal/business attacks out of posts.

That is just bad form in my opinion.

cheers

WOW! Interesting observation. You really hate me! I wonder why? My post has nothing to do with you personally or your business; I just don't care.
These 2 threads were dedicated to sharing experience with using different kinds of glow plugs and I posted mine. Then you claimed that my vehicle had some kind of malfunction which caused the glow plugs failure. This is how it started. Your claim along with other accusations has no ground and leads to unnecessary tension on the forum.
I do not need to explain this but here you go. The only reason why I stopped by CVI on that October morning (I can provide the date if you want) because I was going out of town and I needed to replace the valve cover gasket. I was short on time, otherwise I would do it myself. When Butch was replacing the the valve cover I asked him to replace glow plugs; I experienced rough starts as the mornings were getting colder. I just thought it was a good time to replace glow plugs to have a safe trip. I did not ask for installing Hyundai parts. If you want to know why I got them you have to ask Butch. This is all irrelevant to the subject.
Now, as for a fellow diesel mechanic saying that all 4 pieces cannot go bad if the control system is in a good working condition. Does this mean that 4 glow plugs cannot be of poor quality or just inappropriate for this application? Sorry I don't understand this logic.

I am too old to play games like yours and make fake claims. I have learned my life lessons when you were a kid; you are still learning. I provide facts and share my experience which is always positive if you are willing to learn from it.
The glow plugs on the picture did not brake down at once; they were slowly burning over time. Don't you get it? What damage do you expect to see because of that?
Oh, you want a witness? Ask our new Jasper owner whatthejeez. I was changing oil and filter and replacing glow plugs upon his eyes in my friend's shop to teach him a few tricks.
Are you happy now?
To other fellow Delica owners: this is your choice which parts to use. I do my research most of the time, sometimes I make the wrong decision and I learn from it later. Post your experience with glow plugs and we all learn together. As for me I went with NGK CY-55 ones this time because they were well known to the Delica and Pajero community worldwide and cost less than Hyundai parts if you know where to buy them. I don't expect any surprises this time and can post another report in a year from now if I still drive the same Delica (and if I will be willing to go under fire again).
Cheers,
Sergiy

Hmm... Perhaps instead of slinging pointed words at each other we could take the "Courtesy" approach. It doesn't cost much and it tends to resolve many issues. One can always agree to politely disagree and leave it at that, no? Just a thought.

Been some time since I posted this image:

FWIW Here's a voice from the other side of the Hyundai fence...

I've heard good things about the NGK CY-55 plugs too, but I have just passed my 2 year anniversary since installing Hyundai glow plugs, and they have performed perfectly (Hyundai part number in the thread below):

http://www.delica.ca/forum/glow-plugs-a ... tml#p71563

Do you remember if you were using the same Hyundai part number on your vehicle? The pictures of those four tips all being severely and quite uniformly degraded looks to me like a systemic problem i.e. bad batch of plugs, incorrect voltage rating, excessive on-time, ...?

No doubt the NGK's will work well but like I said - knock on wood for me, 24 months, still starts first crank every time, even below -10 degC for the Hyundai plugs.
