Title: Faark - glow plug broken or thread damaged
Post by: Asterix on June 08, 2016, 19:32:59
Wanted to change the glow plugs. They seem to be very tight, or whatever you say, I don't want to use so much force to unscrew them. The first one I tried just turn in the thread but the glow plug doesn't come up... :sweating:

Anybody aware of a method to get the darn thing out without having to take off the cylinder head... :question:  I'm afraid it's either the glow plug that's broken inside or the threads in the cylinder head that have come loose... :sweating:

Ai! Sorry to hear, Henning :'(

I have no advice for you but is there a way you can tug on it while turning it, maybe it will budge?

No, it's mounted pretty deep, so need to use a deep socket to unscrew the glow plug.

 :Shocked: :disapp:

Can you magnetize the socket or put something sticky on it to help? Say a bit of silicone inside the socket then push it down on the the glowplug and leave it there for say ten minutes to cure/set a bit before pulling it back out?

Oh dear, I warned people to let the dealer do it. :(

"There was an instance mentioned here about a glow plug disintegrating when trying to remove it. It was at a dealership I think and not easy to resolve. Be aware."  :exclaim:

It doesn't sound good Henning.
I cant recommend much more than a bit of WD-40 or equivalent and let it soak. I haven't had it personally but have had very tight threads. I always refit with plenty of copper anti-seize.

It appears that the stuck part in the 2012 post, was drilled through the centre and a screw extractor used to retrieve the part. :exclaim:

All I can think of is what cruiserfied said. Put wd-40 and let it loose things couple of days. I've heard that some have used impact wrenches, but that might be a bit risky. Most diesel shops should have tools to drill and pull those plugs out without removing cylinder head. Costs a little bit, but much cheaper than removing cylinder head.

Post by: Asterix on June 09, 2016, 16:18:55
Thanks guy's

I did use WD40 and I tried both with cold engine and warm engine, no luck. I did grease them with copper grease when I mounted them 4 years / 100,000 km ago.

Now my local ex-Hy dealer have the car and they said they have had the issue before and removed the plugs without removing the cylinder head, so here's me hoping for good news tomorrow...  :Good_luck:  :Good_luck:

Post by: diesel1984 on June 10, 2016, 08:38:24
What you need is penetrating oil not wd40, soak it for a few days and then it should be all fine.
Really cooper grease on threads can make things worse on next plug removal.

Would glow plug grease work better than copper grease? At least febi makes some sort of ceramic assembly grease for glow plugs. It is especially recommended for mercs. I would guess its main purpose is to get the plugs out at some point. Mercs have had lots of issues with stubborn glow plugs what i've heard.

Well, popped in at the workshop after work today and the verdict is the top has to come off... :blubber:

They tried different methods and even have some special tool for this scenario, but all 4 plugs have decided not to leave the threads.. :'(

Life sucks now and then. Hell, I wanted oil & coolant changed anyway.. :crazy1:

Unlucky. The workshop could not do it and now you know that you tried your best and did not fail. Always a positive no matter what. If like me when its all fixed and your car is running well you feel good and the cost becomes history. :goodjob2: :victory:

Could they tell you why they seized? I'm not too familiar with these engines but did the thread inserts (if this engine has them) come loose or did the glow plugs seize inside the threads?

On the positive side, at least you will as you said get new coolant and oil. Maybe you could check out the valve seats and report back on their condition if you wouldn't mind? I'm sure there aren't many teardowns on these engines as they sound like they are super reliable, so see it as an opportunity to remedy anything else you can find while you have the head off.

All the best :goodjob:

Update.

After removing the cylinder head they succeeded removing 2 glow plugs, but the last 2 won't budge. They even send the head to a specialist, who also gave up. The specialist refused to drill them out and insert a new thread (helicoil) because they can't guarantee it will be 100% ok.

Now a second hand cylinder head is ordered from a wrecker arriving late Thursday or Friday morning so won't have the car back for the weekend.

Apparently removing the head on a i30 CRDi is a big job, very time consuming, so before everything is ok again I'm facing a bill of around 4000,- AUD...  :blubber: :blubber: :blubber:  ( which is ca half the car's sales value)

whats the cost of a second hand engine? Over here you can get an engine with 53k on it for $1700.

I don't know what they would cost to install though.

Sorry to read this Henning!!
i used to have a Ford V8 3 valve per cylinder 330 cubic inch in falcon ute had alloy heads the spark plugs where deep and needed a special socket, so went out to my friends who has machine shop & engine dyno. when he went to turn them he said thread sounds dry & if he tried to get them out would strip the threads so soaked in WD40 left them to soak then got them out by first turning clockwise then anti clockwise kept that up & they came out ok friend said factory should coat with copper anti seize but they don't sounds like Hyunday the same.
saw Tim posted that too. a lot of people here & USA all had troutle with those spark plugs striping threads so i did not want to trust a dealer as some had threads strip at dealers dealer blamed the owner saying left too long & carbon on plug thread stripped it, well mine had 200,000 when we removed and the WD40 was the trick

I wonder why they 'welded themselves in' like that in 100K....I would have thought that you were doing the right thing by putting the copper grease on the threads when you installed them.  :crazy1:
Title: Re: Faark - glow plug broken or thread damaged
Post by: Phil №❶ on June 16, 2016, 11:13:10
Just guessing, but towing a van regularly and references to engine getting hotter than normal may have caused this phenomenon.  :question:

I have ordered some Febi ceramic grease and will do just that.

Post by: sundiz on June 16, 2016, 14:18:39
Never heard that the plugs could be stuck so hard that even machine shop could not drill them out. But I guess that is possible...

Did you use torque wrench when you changed them last time? Did you change them previously with hot or cold engine? I would guess they could come out easier with hot block, but at least in the factory they are put in a cold engine.

I hope it all goes well and the bill would be smaller.

I was planning to change my plugs for just in case, but I started really doubt if it worth the risk. My car has done 107tkm with original plugs.

Post by: cruiserfied on June 16, 2016, 15:10:05
Bugger.
Bit of a shame they wouldn't try drilling them out. An engine remanufacturing shop should have drill presses to get it pretty spot on, and if it came to heli-coils they are pretty bloody good. I have had seized exhaust studs cut out, new alloy welded in place, then drilled and retapped before.
Hopefully they go easy on you when the bill comes. Did they price a new bare head?

I believe I can get a similar used one for around the same price, but on top of the already spend hours, they would have to remove the rest of the engine and install the new one. Wouldn't end up cheaper at all.
Had I known the extent of this operation at start, I would have considered that option.

Yes, but I think it's only fair they say no thank if they're sure they can create a perfect result.

Did talk to a colleague who have had same issue with a Land Rover, he had it machined out at a engine remanufacturing shop. I rang them to hear the cost, but it would be nearly the same as I have to pay for that used head the dealer have ordered, so didn't go for that option.

The disaster that has occurred in your car, Henning.... has led me to do lots of reading about glow plugs and faults and problems that people have experienced...and to start a different (yet related glow plug thread):-

:link: Glow plug reamer availability (https://www.i30ownersclub.com/forum/index.php?topic=40555)

(that I perhaps started in the wrong section).

I hope that your i30 will be returned to fine fettle for just a modest fee!

It is strange but the only other diesel vehicle that I have owned was a 1980 Datsun Patrol that STILL has the original glow plugs fitted to it to this day! I wonder if any i30 owners will be able to say this in 2045!
Title: Re: Faark - glow plug broken or thread damaged
Post by: diesel1984 on June 18, 2016, 13:52:25
NEVER put copper or any other grease on glow plug threads specially on engines with aluminium head. The OEM install doesn't have any grease.
Grease can go on heads with non alu material threads/head.
OLD mechanics and new engines NO NO NO.

NEVER buy cheap glow plugs with cheap chrome and fragile parts. This engine have NGK original plugs so always buy this one only.

Tighten always with torque wrench 8Nm.

Before loosing spray with penetrating oil or ATF mix fluid few days.. NOT with wd 40, he is not for this kind of job.

Remove with hot engine, install at cold.

Follow these steps and you will never have any problems of this kind. :goodjob:

Got the car back today, will be so nice to drive my i30 again...  :D

There's oil in the coolant reservoir, that shouldn't be there after a head removal. Will have a talk to the workshop tomorrow, but might wait with too aggressive complaints until I receive the invoice... :confused:

Had a 2004 Getz CRDi as a loaner, what a piece of crap. Only 150.000 km on the odo, but terrible to drive. Suspension horrible soft, seating position not suitable for my 182 cm, and a lot of other things, mainly due to poor maintenance.

It would be great to know what additive they put in....and why...

No additive like that is recommended by Hy in Australia.

Did they give you an idea of why the glow plugs weren't able to be extracted...or any ideas on how to prevent this from recurring?
