Glow Plug gone?

[Midlander]

I think....well pretty sure anyway, that one of the glow plugs has had enough....

Symptoms are....
only does it on 1st start of the morning when cold....like it is now.
Starts 1st time after dash light (glow plug) goes out.
But get a cloud of white / grey smoke then settles but a bit lumpy on tick over till warm.
sometimes ticks over close to 1000rpm till i drive off then it settles at 750 / 850 rpm when i stop at junction 50yds down the road...

after that and any subsequent starting during the rest of the day is normal..

Does my diagnosis sound about right?

sounds about right, easy enough to check remove the wires/straps from the terminals on top of the plugs and test each one with a ohm meter good plug will read 0 ohms, if you do not have a metre then get a bit of wire from the + battery terminal and flash it on each plug, you should see a spark, do it several times on each plug, if you have one that does not spark at all you have found the bad one, Rick

 

[Midlander]

Cheers for confirmation...will have a poke about when i get a chance.

Take care when removing glow plugs, one of mine snapped. Suggest you use freeing oil before removing.

Also use a "T" bar to save putting a side force on the plug.

The "T" bar will give rotational force only.

Might still shear at the base though:augie

....Don't say things like that....you're scareing me now

 

[(RIP) PLANK]

on a lighter note, the first glow-plugs i ever changed myself were in an early T2 TD and i used no oil and had no problems, got replacements cheap enough (original brand) from the motor factors down the road from my house! But i do remember using a T bar :thumb2

 

[Midlander]

Fingers crossed it all goes well when i sort it.

I must admit, the truck has behaved itself so far when i've had to work on it...not fought back etc.


Probably just jinxed it now lol

Sounds like glow plug mine miss dites badly on start up in cold

Glow Plugs sound like your issue matey

T Bar all the way as the guys have said or you'll end up with a snap on your hands and they are no fun to get out!!

The wife tells me she has been having a the same trouble and as I'm due to give the terrano a service I think I'll replace the glow plugs at the same time never done them since we got it and can see when they were last done in the service history.

So if been looking at the NGK ones and it seems NGK and others list cy58 which are 25 quid each and ceramic but if also seen on a south African site that y707rs also fit and the only difference is there metal not ceramic and take 2 seconds longer to reach max temp and their only 15 quid for 4 much better. So am I right to buy and fit the cheaper glow plugs?

so after a nice warm summer im going to get around this week end to changing my glow plugs 2 are defo fecked and iv bought the y707rs ones above and as suspected the motor factors wanted over 100 quid for cy58 ceramic on inspection they are almost identical the 707s are a little longer on the electrode so if any one has an old glow plug laying around from a tdi can you measure it for me just in case i will compare when i remove any ways but would be nice to know before i start
thanks

do not like the ceramic versions, when they fail they break up and must do some damage on exiting the combustion chamber, Rick

I have a question (and don't laugh!)...

Can you use a spark plug tool to remove a glow plug? Or are they different sizes etc? :nenau

I've changed spark plugs in the past as well as glow plugs, but I've never compared them or considered whether one tool fits all

22mm deep socket IIRC.

I've not done my plugs on this car, are they under the intercooler on the TDi?

so the simple answer is no the tdi needs cy58 glow plugs the ones i bought were meant to be metal replacements but the element is longer and more importantly thicker so wont go in turns out i only had 1 gone so replaced it while i was there checked all the others
while they were out simple job. plus gas if your friend they all came out easily. replaced all the belts at the same time just got the electric fans to fit now

 

[solarman216]

Yes...

mine are 12 mm socket, on a tdi, rick
