I JUST WONDERING IF YOU COULD HELP.I,VE GOT A 1994 DISCO 300TDI.THE FAULT IS THAT IT KEEPS FOULING UP NUMBER 3 GLOW PLUG WITH OIL. NUMBER 1,2,4 ARE FINE. JUST WONDERING IF THERE IS A OIL GALLERY NEAR THERE. HAS ANY ONE HAD THE SAME FAULT

THANKS AARON :cry:  :cry:  :cry:

I just replaced all my plugs and no.3 on mine was also black (looked like carbon) but all the other were clean.  Don't know why though.

hobbit:
If the fouling is oil, could be a valve seal or piston rings
If it is soot, might be worth checking the injector for fouling, or incorrect spray pattern, of the break off preassure is out

muddydisco:
its like the number three glow plug has been dipped in a bucket of oil,

hobbit:
Need to do a compression test first, then squirt some oil in the bore and retest it, if the compression goes up, it will probably be a top end prob
