300tdi belt tensioner
Matt_H:
--- Quote from: "muddyjames" ---I have been told by mates at the weekend who are very land rovery minded that it is probably the key way into the engine hence why the pully was wobbling hence the shreaded belt so the cam belt is probably nearly shreaded as well and if it is wobbling the belt wont be going round the right speed so the timing maybe very slightly out. Thats their thought any way.
I will find out later on today the extend of the damage.
THe garage in Banbury is a one man band guy who used to work on john deer machinery and gave that up quiet a few years back and now specialises in Landies. He charges £25 per hour. No quotes as no idea on exactly what is wrong.

How does timing out give white smoke? Surely it would be black smoke if timing was out.

muddysteve:
our engines chuck out white smoke when the fuel pump timing's out
white smoke is unburnt fuel or steam. there were no bubbles in the header tanks and the pressure in the water system was ok when i looked at it.
i reckon its down to fueling rather than anything to serious we have it at work quite often when an injector or 2 go down on an engine they throw out plumes of white smoke and wont rev.
silly question james you did put diesel in it not petrol? as this would cause lots of smoke
Steve
muddyjames:
I definately put diesel in it!!!
Garage said it is definately the pully off the cam chaft (or what ever shaft comes out to turn the cam belt pully) and the nut that should be at extreme torque worked its way loose so the timing is slightly out. will find out how much damage was done soon.
Xtremeteam:
if the bolt has become slack it CANT change the timing,all that can happen is it shreds the belt quite quickly as it runs off line,the only pulley that can change the timing is the one on the front of the injection pump
muddyjames:
so changing the pully may not solve the white smoke?
I will call the mechanic tomorrow and ask him whats what. it sounds like it could go into thousands at this rate.
I have been well and truly conned
