Glow Plugs

solarman216 · 18-09-2014, 00:14

I need some glow plugs for the Mrs motor as three have gone down, all the local factors can offer are Ceramic which I will not fit, it seems the Lucas LP079 is also ceramic so who does Metal ones??????? Rick

I ordered these ones, which say they are LP079's, but as you know, had metal tips.

OK so what's the aversion to Ceramic it seems to work in Spark Plugs ?

The blueprint ones we fitted at work certainly looked solid (no tip as far as I could tell)

If my memory serves me right

The ceramic in these is very different, some how it is metalized in order to conduct electricity that is how they get hot, problem is the whole tip breaks away when they fail and there is no room for it between piston and head so it gets broken up and embedded in the piston, not to bad if it stays near the middle but if it happens near the edge the piston deforms, trapping the rings = goodby engine, I have one here just like it, Rick

NGK "CY" indicates they are Ceramic, Rick

zippy656 · 18-09-2014, 11:13

ok. Will dig later

solarman216 · 18-09-2014, 19:32

OK well here is a pic of two types of glow plug, 1st on the left is a metal one by "Wega" not a good make as the one in the pic is one of 4 I fitted new only a year ago, and they bar one have failed, not because they have burned out (as you can see the tip is in good order) but they just fail to work, next is a good ceramic, and then two more ceramic after failure,

solarman216 · 18-09-2014, 19:38

this shows where the tip ends up, you can see they just break off in a big lump, hence the similar shape hole in the piston, as time goes on it gets broken up smaller and makes lots more indentations and if unlucky, near the rings jamming them up as in this case, so now you understand why I will not ever fit Ceramic, three more pics follow this one, all the same engine, Rick

solarman216 · 18-09-2014, 19:41

more damage

solarman216 · 18-09-2014, 19:43

and more

solarman216 · 18-09-2014, 19:46

sorry that last pic was another shot of the same piston, but this one shows the damage the little bits do, this engine as a result almost ran away but managed to stall it, Rick
