I normaly get mine from ebay but only buy the ngk ones.They are expensive so would put meter on them and just replace the dead ones

[zippy656]

how do you test them with a meter?

not worth changing all as all same age, save messing about changing the others later??

Can change the lot but are expensive.If you disconnect them then just put meter across them if good will be dead short same as light bulb

ordered 4.. less than £90 save me time later. after all they have all done the same 140K...

only done water pump in the 6 years we have had it, so cant be to bad

how long SHOULD it take me to change them, any tips??

About an hour ish. Just be careful undoing the link rail thing, there's some fancy bakerlite type screws on top that will brake easily. Squirt plenty of skoosh on first and also make sure the area is clean. It's best to avoid clods of earth entering the cylinders :lol
Oh yeh, a cool engine :thumbs

[zippy656]

all done, all the bakerlite bits broke!!

but new plugs had new ones... yay

all went well. under an hour!

Well done Zipmiester, love it when a plan comes together :D

Great thinking of doing these myself, but the bits you speak of that broke, are they available to replace or aren't you bothering?

The nuts that come with the new plugs are fine.
The advantage on the "bakelite" ones is that they are insulated, so prevents shorts if you happen to leave spanners or tools in the area if you happen to start the engine.

The screw driver slot in the top of the bakelite ones encourages the plastic to break apart, leaving the brass insert, so at least the new nuts can be tightened with a small spanner.:thumb2

i think ive got gummy rings, so will be looking into water injection over the next few weeks

[arcascomp]

What makes you think that?

Wondered about water/steam injection but non too sure where to stuff the steam into?

Is that a new term for colonic irrigation or something? :augie:augie:augie


:lol:lol:lol

Yes zippy what makes u think they r gummy I have been told that running 100% svo on start up when engine is lumpy can cause ring gumming. that's y I have twin tank:thumbs

When you say gummy rings, is that injector ring or piston rings:eek:

Just wondered as I'm running svo at moment

Just wondered as I'm running svo at momentpiston rings injectors dont have rings from what i have heard its what happens when the oil is not completly burnt i.e when the engine starts in morning and i guess when its running lumpy but it will take avery long time as its not lumpy for long

[zippy656]

Hard to start and lumpy running

changed glow plugs, but still a sod to start.

maybe duff glow plug relay, but not sure how to test that

[makeitfit]

Zippy, if there's no change to your starting issues after you replaced all of the plugs, I'd be looking at the glow plug relay.
A simple light bulb test would suffice :thumb2
Gummy rings will take absolutely ages to take effect and Zippy runs a mix too:sly
As regards water injection, you can put that into the oil blow by insert on the rubber pipe after the maf. See my LPG injection thread for details :cool:

[zippy656]

OK so how do I test the relay with a bulb?

[makeitfit]

Stick one end on the wire that goes to the glow plugs and the other end to earth. Switch on and there should be light :thumbs

[zippy656]

ok off to try that.


other thread now closed

yep, light works, then off, after few second comes back on... ect..

will get battery looked at next week, still under garrenttee

[makeitfit]

Hmmm, not sure it should do that :nenau I think it should come on for a few seconds and then go out and stay out. So it could be the timer part of the solenoid is iffy. Get another from the scrappy and try again:thumb2
There maybe some electrickery expert along later who knows more. i assume you had good contact on the wire and bulb arrangement:augie
