Glow Plugs NGK = FAIL

so went to do a leak test on my car (tester broke but that's another story)

removed the glow plugs that are less than a few months old to find this







guess this explains why I kept getting this message ….

what type of fuel? Diesel or veggie oil, bio fuel, and did you ever use easy start with them? Or you got a tuner/chipped

Been running Black Diesel for the last year or so, the last set were only replaced as 1 had failed so replaced the lot as may as well while I was getting dirty but these were the OE plugs from new and they came out in better shape!

seems you either have poor plugs or some serious temps or injector issues

did you use any easy start/either to start your car?

I have done recently but only because the glow plugs have not been working

It could of been the glow plug relay/fuse,or timer that went south. plus a low, or weak battery which does not spin the engine fast enough, will cause a hard start.
I have New batteries in mine (2, 24v starting) and this winter Jan and Feb -40f at night. When it would sit for 2-3 days, It would not start, but When I the battery charger on for 1/2 a hr then they were back at 100% and good to go. If I started it every day then no problem, only when sitting for 2-3 with out starting I had to charge batteries.

Those glow plugs melted from using either/easy start and nothing else. No fault of the glow plugs

that was the first thing to get pulled and tested when the fault occurred, it's the plugs causing the fault.

I've started a transit ever day on easy start for over a year because the relay was knackered, once I changed the relay it started on the plugs fine. the amount of easy start needed to melt plugs would be popping gaskets and holes in pistons

isnt it a indirect diesel

Maybe something to do with the ****e you use as fuel. I have never seen glow plugs as bad as that. God knows what the rest of the combustion chambers, valves and seats are like. No wonder it's not running well.

you better check your injectors aswell black diesel did this to my doner motor, they dont rev high enough to burn the carbon left in old engine oil, (amongst other acidy ****) even with fuel additives my injectors had a sandy coloured carbon cone shape growing on them, i was cutting old oil 50/50 with kerro after going through a three stage filtration system. black diesel is an engine killer! unless multi filtered or centrifuged. i will never use it in this vehicle. ps it did go quite fast though

IIRC, it is made from old engine oil and things of that nature.

used engine oil then filtered and cut to make a very cheap diesel

black diesel, is old used engine oil filtered and cut with kerro, red diesel, or pump diesel then in your tank and off you go, straight down doom ally, it does work if filtered properly or put through a centrifuge but works best in higher revving engines, not p38s, ill try and put some pics on of my injectors they were unbelievable, if it was a D.I the piston would have hit the carbon build up on them,

could you put lots of pics so we can see what the black oil does or does not do to engines?
