Cold Start

[harpster]

hi :D

when starting car in the morning (starts first time) it starts to chug and give off lots of blueish black smoke for 2-3 min, but if i turn it off and start it back it runs alot smoother. it is only on the first starty of the day i get this problem, What can be the cause, Could it be temp sensor/glowplugs or timing problem !!

also it is only giving me 360 miles to 55 litres of deisel.. (city miles) was giving me 440 miles

I'm having very similar problems.

 

Think I need to change the Glow plugs at 118,000miles.

 

How do I release the 1 piece bar that seems to connect to all 4?

 

I'm worried about breaking it if I pull too hard without some advice.

The answer is none of above :16: what it is most likley thin oil in cylinder head / rocker cover seaping through worn valve grommets into combustion chamber over night burning off on start hence blue smoke nothing to worry about just watch oil if you start using alot the grommets are penies to change just akward cams off cam belt etc.

The advice is ....strong pull/tug ....its a tight fit....don't be scared.

id go for valve stem oil seals not plugs. a test is to get to 70 say take foot off accelerator for say 5 or so secs then back on watch mirror watch for big puff of blue smoke thats oil burning if its there not diesel as injectors are switched off on overrun. just watch your oil level as above

Sorry cyborg and zorgman it is not oil burning.

 

Changed 4 glow plugs as all were open circuited (burnt out) with a very high resistance measurement. Can be measured in situ.

New plugs measured less than one ohm. meaning they take a lot of current and get hot when operating. Needed to buy a 10mm deep socket to extract and refit.

 

In the recent cold weather, (I normally miss this as I am usually in Spain caravanning at this time of year) not only has the car been difficult to start but also would not pull below 2000 revs for some time whilst cold. The temperature up here on the Pennines has not been above 2-3C degrees recently.

 

I kept thinking that it could be the MAF, I had bought a spare one about 40,000miles ago, or the brake switch as mentioned elsewhere.

 

I have read somewhere else that these plugs keep operating when the temperature of the fuel is low so the symptoms mentioned make sense.

Have not been able to check the fuel consumption yet.

 

 

Next problem is the auxiliary heater glow plug. That has not worked for at least 2 years.

ah well the decription below u describe is not a glow plug fault if it starts first time your describing oil seepage as excess fuel is white. glow plugs deffo dont affect mpg but temp does which you describe in second lot and also affects bad starting so thats what threw us off scent. its very hard to give a diagnostic of faults via net as unburnt fuel is white burnt oil is blue, long as your sorted out
