I allus waits till it's rockhard before I do any screwing. but each to his own heh????

woooooooooooooooooooooooooooooooooooooooooooooo!!! hold up are you seriously saying you are just 'nip' up glow plugs that have to hold back combustion pressure in a high compression diesel engine!!!! now fecking chance do them up tight

i didnt say nip em up. i just said not rock 'ard. some of you big feckers cant alf do some damage with a spanner! not rock ard to me is all the strength i can muster!

i put copperslip on the threads (helps when you come to take em out) then do em up FT

Cheers guys Did them up tight and put copper grease on thum
Only did three of thum cos it's all the shop had, have tae wait till monday to do the other one.
Now ah'm hopin' this is nowt tooo serious but why's the old gp's lookin' loike they are?

This is the furst nearest the front....



and after a wipe....



This is the second....



notice the tip is all sooted up.

Never did the 3rd one as still to get it on monday as the shop ran out

The last one looks like this....



the tip is a whitish colour

any ideas or is this normal?????

Anybody?

First two look pretty normal, last one looks like its been running hot, nothing to worry about really especially if they havent been changed for a while!!!

the first one has a rocker cover leak? as above it looks like no looks burned

Additionally, contrary to popular belief glow plugs don't need to be ridiculously tight, just nipped up!!! Just cause its a combustion chamber doesnt mean its gonna blow the plugs clean out and through the bonnet, nipped up nicely is fine!!! Bearing in mind i used to run a 410bhp escort cosworth running 2bar of boost, the plugs on that were only nipped up so im sure the plugs on a landy will be fine!!!

Cheers tom Ah've had the bus for a year or so and never changed the plugs, and ah don't know when/if the last owner changed thum either.

what cr is the cossie running 13:1? 14:1? that kind of pressure will work a glowplug loose! i have seen one leave an engine bay because an apprentice has left it just 'nipped' it cost a new bus bar on the motor and a new headlight in the car it hit oh and nearly the guys eyesight

Ok yeah 'nipped up' is probably the wrong phrase, but theres no need to start getting a 21ft scaff pole on your wrench to get em tight. Regards compression ratio on the cossie it was 7.6:1 - low compression to accomodate the additional pressure. What CR do landies run?? I'd be interested to know actually!!

does that mean it does G-spot? if so, how can ah tell?

Eh?????

Thinking aloud here and i may have got the wrong end of the stick here, but surely a land rover can't have a compression ratio of 13.1 or 14.1 especially on a turbo engine. I mean some guys I used know that had converted cosworth YB engines to N/A and were using that sort of compression ratio were using 24v starter packs not so much in the 12:1's but certainly 13.5:1 and above!!

is yer rocker cover leakin just above the first glow plug?

there was boobs on the telly

diesel engine or compression ignition engines to give them there correct title thrive on high cr without it they don't work, the N/A YB with 13.5:1? petrol will detonate at 12:1 they mustahave been running nitro-methane or labgas just to stop it ripping its self apart
