Another glow plug thread

[lopar]

I tested mine the other day and it seems to work fine cuts out after you hear the click, but I noticed when it was running it was powered up again until the motor was warm, Is this normal?

yes, this is suppose to help with emissions, 2-3 minutes "ish" after start-up is normal, this is the reason the correct glow plugs are so important. Many, if not most, diesels of this vintage do not have this long after burn requiring special ceramic self regulating plugs to handle such a long burn time.

Thanks for the tips psilosin... will try that this week and see if I can isolate where it's happening.

Sent a price question out to a supplier and got the following response if anyone thinks that they want to pick up the reigns for a L400 plug group buy, let me know, and I will give you contact e-mail.

First I have heard about the Denso plugs............

I will not be getting involved in this as I sold my delica 1.5 months ago

"Good morning.

Best we can offer is a 10% discount for 100 pieces of CY55, £18.31 (+vat)
each. You may wish to consider Denso ceramic equivalent part DG-306, where
we can apply a 15% discount and the list price is lower making price £15.08
(+vat) per plug. The quality of the Denso part is as good as the NGK part, I
have been using them in my own Delica for the last year and a half.

We would need to try a few options for least expensive ship method, let us
know if you want us to check."

Cheers!

We have tried many different brands of glow plugs for the 4M40 with most aftermarket brands failing remarkably soon after installation. These failures include the ADL Blueprint, HKT, Hyundai and a german brand that are being sold locally. We warranty our work and have replaced many sets due to premature failure. Better to buy good once than two or three sets of cheap. The key seems to be that the glow plugs will be glowing for up to three minutes after the engine starts and unless they are the true ceramic glow plugs (Mitsubishi or NGK) they cannot withstand the long cycle time and so fail. Mitsubishi charge an arm and a leg for theirs but the NGK are far more reasonable as you can almost buy a set of four for the price of one genuine. Looking at the NGK glow plug they are identical to the genuine and are one of the same thing. I have had discussions with NGK canada and USA to see if they were willing to import them to North America but as this market is very limited they say it is not economically viable. I currently import them 100 at a time direct from the UK and retail them for $52 each.

Well, I am supplying Hyundai 11V glow plugs .

Hyundai 11V glow plugs have 'built-in resistor' (variable resistance versus engine temperature) to prevent overheating as Glen noted.

As far as I know,all NGK glow plugs that are identical to Mitsubishi OEM cannot be sold based on contract.
So any cheaper NGK GPs are just similar ones or copies.(one piece of Mitsubishi OEM glow plug costs $100 from shelf. )

[quote=]So who is the manufacturer of these plugs? I know for the l400, the factory Mitsubishi glow plugs are made by NGK exclusively for Mitsubishi. I would think the same would be true for the other glow plugs sold by Mitsubishi, made by one of the major companies for Mitsubishi. The Japanese auto makers are famous for reverse engineering, finding the best product and using it for their application rather than trying to reinvent something and build it themselves. I don't know if this is true of the 6V glow plugs, but it would stand to reason. Any idea who makes them? [/quote]

Here are some discussion threads we already had.

We are selling Hyundai 11V glow plugs at $120 for box ( 4 pieces ), $35 each.
Same price will be applied to jobbers.

I am not stating where they were purchased. The customer that came into our shop with starting issues told us that they were Hyundai glow plugs installed in his van and upon inspection they had all failed. I am also not stating that the NGK plugs are better than anyone else, just that they are tried and tested way of insuring good quality glow plugs. On both the UK and Australia forums the NGK CY55 glow plugs have been used for many years with very good feedback on reliabliity. This is a statement of experience only.

[jessef]

Mitsubishi OEM's last the longest at 10+ years
NGK CY55's a close 2nd

All others, Hyundai's included are a distant last with unknown and inconsistent longevity

This has been discussed, tested and proven on other forums long before Canada saw it's first Delica and this forum even existed. Rehashing it over and over is like reading the same book twice. It's still the same book.

All I know is from personal experience and that being I had the worst luck with the HKT PLugs and the two that failed before I replaced them were HKT plugs and the two that were rusty and old but still worked were OEM plugs. The hyundai are better then the HKT one IMO but now it seems that I have to cycle them 3 times to get a clean start. And everything else in the system is in good shape....now with summer coming up I'm not worried about it so much but come next winter I think I'll give the NGK plugs a go and see what happens.

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.

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.

If his glow plug relay had failed his glow plugs would get 0 power not constant power.

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

We had encountered a similar issue when we serviced newly arrived L400 before selling , we decided to part out.

Nothin like a delica.ca dustup to brighten up a dreary overcast holiday! Here are a couple of nuggets I found poking around my navel lint.

On selecting parts for your vehicle:

A penny saved is a dollar spent.


On selling parts that suck:

You can shear a sheep a long long time but you can only skin 'em once.

OK I understand what you are saying now.

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.
