Fairly new to this land rover thing but im getting there. Anyway, its a 98 300tdi and the last week or so im getting a puff of smoke at startup and the revs idle at just under 500rpm building up to the normal 750 after a few minutes, also theres this tapping/ticking noise which goes after driving for a bit. I did the tappetts hoping that would cure the problem but it hasnt.
Does anyone have any ideas? I thought perhaps lift pump.
 
What colour smoke?
Blue is burning oil.
Black is excess fuel (unlikely in your case)
White can be water (unlikely)
OR unburnt fuel vapour. Have a sniff of it.
Tapping noise: try to localise it; a mechanics stethoscope is good, or a long screwdriver held against the engine with the handle pushed against you ear. ! keep hair fingers clothing away from fan etc!
 
Smoke seems to be unburnt fuel and the noise (getting louder) is loudest on the fuel pump. What are these like to change? Can they just be rebuilt?
 
Ive reset all the pump mods i did back to standard, they were smoke screw 90deg, star wheel 180deg and diaphragm 45deg plus a half turn on max fuel screw on the back.
How would i tell if the timing was out?
 
Basically perfomance, wasnt good at all. Dont get me wrong, im not wanting ferrari standards just a touch more get up and go out of junctions etc.

Check all basic settings and hoses,(both fuel and turbo), there are lots of reasons for poor performance, crap servicing is a favorite.

When you've done that then you can tweak the performance.
