Thread: Td5 Glow Plugs

If you'll remove the head once you'll see clearely the difference how the 5'th cylinder and the associated valves are more "contaminated"... provided the other 4 were working well all the time

I guess I should have been more precise.

I have never had the glow plug light illuminate for 3.5 years ,Except for the self test that lasts about 2 seconds.

BTW ,when I checked just now it reminded me that I have never had the water in fuel filter light illuminate, except for the self check. They are next to each other. Funny how some have had lots of trouble with them.

If it was only chaffing wires one would think LR should have fixed it rather than deleting the light. Waterwatch and others make lots of money fitting aftermarket sensore to Jap cars . Go figgure.

Isn't number 5 the cylinder that gets "dusted" ? co incidence?

Maybe OffTrack or somebody else who can dig within the ECU's brain could tell us how the glow plugs management is set and what's the temperature limit where the ''pre-heat'' operation begins and how the operation time is calculated cos that's coincident with the warning lamp operation too... what i did was to bring a wire into the cabin from the glow plug relay output, connected a bulb to it and watching ECT with nanocom i clocked the post heat operation... i've got between 1 and 3 minutes depending on outside temp untill the bulb extinguished and it happenned all the time when the ECT reached 20*C.(i made these tests in october - november last year in different days while the outside temp in the morning varied between 0 - 10*C and kept the FBH on to not let the engine idle too much)

You will know when they aren't working.In winter you don't get that instant fire and instant smooth idle.
Don't buy cheap replacements,they only last 18months down here.
Even in summer you can tell when you loose one.

Andy. This is the reason for my thread. I am having all sorts of issues with my engine, mainly blowing a lot of black smoke, especially when first started and then only at idle.
For the first minute at about 1200 rpm it is really running rough.

Once driven all is fine, except for small amounts of black smoke at idle.

Although I don't think that glow plugs are causing this, I am about to do something that I have never done before and that is to take it to a repair shop.

I want to make sure that things I can do are done to eliminate labor costs.
