Outer Limits 4x4 Board

Guys, if you have oil on 2(next to each other) out of your 6 glow plugs, What does this meen?

if the rig is using oil as well id say a bit of blow buy ie oil getting past the rings

Dosn't chew up any oil between 5000km changes.

do the plugs work?

As far as I know yes.

pull them out and put them across the battery for a few seconds, they should glow red hot. if they work, then it's possible you have some bore glazing preventing good oil control (or the rings are just plain worn out), give it an oil change using some oil flus concentrate stuff (200ml of diesel in the oil will do), then take it for a good hard run. you might get back a tad of power you didn't know you had.

cheers

What is meant by that? I've heard it before but don't quite understand it Also is it safe, if the battery puts on 12V wont it kill my plugs?( I'm asking this not knowing how many volts go into my plugs)

no it won't kill your plugs.

bore glazing is where the inside of the cylinders gets coated with a glassy varnish which makes them look very shiny and prevents the rings from sealing propery. it happens to motors that don't get loaded or spend too much time at constant rpm.

True, some glowies are rated at 7 and 11 volts.

So how exactly do you test the on your battery. Thanks guys.

Guys, tested all 6 glow plugs today at Tafe. All worked fine:). although plug number 1 and 2 had a lesser amount of oil. I've been told that it's possibaly the rings or the valve stem cover.

valve stem seals are never much of an issue on diesels as there is never much manifold vacuum. even though the 2H uses a throttle butterfly to control fueling there is also a large bypass and there is never significant vacuum.

are the plugs actually wet with oil, or just black? if black, it could be a symptom of overfuelling. how much exhaust smoke do you get, and what colour is it?

They were black but that was just carbon build up I gather. When I first check about a month ago they were covered in the oil. Now I checked again tonday and there was minimal oil just under the lowest part of the thread. I was told to look for blue smoke, but I've never ever seen blue smoke only faint white/grey smoke sometimes on starup/takeoffs.
