Removing a rounded-off glowplug

Abo · 2008-02-25T08:35:54+00:00

I've managed to replace three of the four glowplugs in my 306 Turbo Diesel (the two at either ends were bastards; lack of access...). During previous ownership one of the glowplugs has been rounded off.Does anyone have any suggestions on how to get it out? I thought about locking a couple of 8mm nuts onto the electrode and seeing if that would turn it, but a vice test on an old glowplug showed it was dead easy to shear the electrode off. I also considered hammering an undersized socket on and seeing if that would work but the electrode won't allow a standard-sized socket to fit on with the ratchet or extension bar. I guess I could buy a deep socket.There isn't enough access to e.g. get a pipe wrench or mole grips on.Any suggestions on how to remove it? I'm obviously conscious that maybe the thing is in there dead tight which caused whoever in the past to round it off, so I'm a little concerned about shearing the thing off which would be a nightmare...

yeah, follow where the fuel pipe come out of the fuel filter. If it says Bosch, run it on 50:50 veg/diesel. If it says Lucas (like mine) well, I've ran 2000 miles on almost straight bio now so the Lucas can either handle it (as suggested on a website I saw), or I'm chancing it...

People do sell it at the pump; the two places I've bought it from are industrial units with a pump inside. They're happy to sell it in bulk, I usually buy 60 litres in containers on top of filling the tank up, because I don't have a local supplier that I know of. They'll sell it in whatever bulk quantities you want, they've got IBC's, drums etc.

Yeah, look on the side down toward the bottom of the car, it'll have a Lucas badge on it ;)

ISTR the Bosch one has a different arrangement for it's cables but I can't remember what it looks like. There is a picture in my Haynes manual, but I can't find it lol

A quick bit of googling suggests the bosch is the pump to have (according to Elsbett, a fatherland SVO conversion firm), so you might be chancing it.

The Bosch one's shorter but that doesn't really help unless you've got a Lucas one to compare it with :-)

Mine has the lucas pump. I can take a pic if it would be useful for elimination.

Bosch is the one to have for running Bio - the lucas has the weak shaft inside the pump somewhere which can go snap if you use gloopy fuel.

The filling station has closed but I believe the members club still exists.

Bio is no gloopier than dino. Veg oil is. Veg will kipper a lucas pump without modifications to the fuel system, a Bosch will be fine.
