one-off smoke during start-ups only

[Aben Dean]

My Patrol gives out a big Fat smoke (once only) whenever i start it up after leaving it off for few minutes... i dont think its normal. I sometimes feel embarrassed because of this....injectors n pump were serviced recently. any idea what it can be?

Diesel I take it. My 3ltr Di doesn't blow one bit of smoke. What colour is the smoke? Does it do this when hot too?

If its a 2.8 I would say it's normal (without seeing it). Mine is and smoke is just part of what it does.

Mine puffs out on start to td 42 totally normal


Just tap it in just tappy tappy tappy

Does it crank much before firing up? If it cranks over a few times before it fires it will puff smoke as the cylinders are loaded up with diesel before it fires. Also is it more noticeable when cold?

Mine would be a wisp at start up then nothing

i think mine is little more then normal...maybe because of direct exhaust system (one resonator in the middle only). its TD42t. if i off and start again, wont happen.

How many seconds roughly to start?

My 4.2 does it as well. Just a small puff when started form cold. I have heard it is normal.

Mine will do it if I turn the ignition on and leave it for any more then say 20 seconds, it will crank over a fair few times before starting and blow a puff of smoke,

But if I turn it on and start it as soon as the plug light goes out, then it starts straight away and no smoke or anything.

My 4.2 also puts out a large cloud of black smoke on start-up, I just put that down to the modified fuel pump....................so much fun when someone is parked behind me with their window down.
