hodge911 Posted November 23, 2011 Report Share Posted November 23, 2011 (edited) hi peeps bought a Lreg 2.4td ssrx hilux surf a few weeks back and after doing the jobs that needed doing done about 400 miles when engine started making horrible noise so after doing the injectors and some other things it didnt fix the fault so decided to go the route of replacing the engine. well anyway today i changed the injectors in the second hand engine for the new ones and thought i,d take the glow plugs out of both engines to test them on a battery . the second hand engine ones looked normal if not a bit sooty but when i took the ones out of my noisey engine i was very suprised to find all 4 were missing the last 2/3mm and looked like something had chewed the ends off i cant understand how it still started [was a little lumpy for the first few seconds]. will post pics soon . so any ideas ???????. in the pic with 2 glow plugs the one on the left is normal the one on right is the damaged one [ all 4 are like that ] Edited November 23, 2011 by hodge911 Quote Link to comment Share on other sites More sharing options...

If it has I'm not sure why I know smoe of the early surfs were renowed for cam shaft problems ,just my guess and somone else may be tell more, hope this is a help.Cheers Dave.

Cambelt snapping wouldnt do the glow plugs... could be the wrong length plugs were fitted?? or faling that the the big ends are completely kaput and allowing the pistons to travel further up the cylinders hitting the plugs?? Let us knw when you find out. Quote Link to comment Share on other sites More sharing options...
Royboy Posted November 24, 2011 Report Share Posted November 24, 2011 Ive seen a few glow plugs burn out. Allways cheap makes so for a extra couple of quid buy yourself some quality glow plugs !! Quote Link to comment Share on other sites More sharing options...
Dr_evil Posted November 25, 2011 Report Share Posted November 25, 2011 Just so you know the 2.4 are notoriously bad for head problems, you should always go with the 3.0 Quote Link to comment Share on other sites More sharing options...
bedwards1966 Posted November 25, 2011 Report Share Posted November 25, 2011 I've seen glow plugs melt, and the remains get embedded into the piston, causing nasty knocking. As it's all 4 plugs, assuming they are the correct length plugs as already suggested, perhaps an electrical problem could have caused them all to run too hot, melting the tips off? I've never known of it happening, it's just a thought. Perhaps they've been left on too long at some point in their life. Some engines can start well without heat, it just depends on the engine design, compression, general wear and the conditions. Quote Link to comment Share on other sites More sharing options...
