Re: grand espace diesel smoking

That's a bad habit that Espace has....you should ask the doctor for patches:d sorry couldn't resist:eek:,

When were the heater plugs last changed ?? if it was me i would guess you have a bad heater plug?plugs if your getting poor starting from cold? but i could be wrong,

Iam sure another member will help soon,

Cheers Don

Cars eh:rolleyes:

Like i said its only a guess but a bad or failing heater plug would cause you to have a poor starting from cold so like i said that might be a good starting point to have them checked or even replaced,

Like i said wait for other members to help as i might be wrong,

Cheers Don

Re: grand espace diesel smoking

yes donald is correct you may well have a couple of duff heater plugs but they are a pain to do and be warned sometimes they break :(

This is NOT what is making it smoke though what colour do you think the smoke is black grey is fuel blueish is more worrying as is oil related and could mean something is worn turbo seals or whatever

Having said that some espaces do seem to smoke a little and still run fine mines included !!

Re: grand espace diesel smoking

If its only smoking under load then i would not worry too much they all do lol

might be the egr valve not closing fully recirculating some exhaust gases when it should not

Re: renault grand espace 2.2td injectors

Hi i doubt that is your problem but you can get your own reconditioned i can do you a set of secondhand ones from a known good engine but as i say it probably won't help the smoke
Having the injectors out will make it easier to check/replace the heaterplugs though !!

Hi thanks for your email. In the mornings when I start the car it sounds like a bag of spanners. The garage I went to said it was the injectors leaking overnight into the engine that's wot is causing the noise when I start it. Also where the fuel filter is there is air in the system. Also what price was your injectors many thanks alan

Re: renault grand espace 2.2td injectors

Hi injectors leaking could make it noisy but to be honest so could the air in the system as the fuel pressure will be too low initially
Try this before you start it tomorrow pump the hand primer next to the filter till it seems to be hard or no more bubbles are seen in the pipes then start car as normal if it starts better then the air is the problem

If not then injectors could possibly be the cause i can do a set for £50 known good ones from my own engine i replaced it due to head gasket needing done

thanks went outside to car it was quiet out there pumped the primer, i could here abit of a sis sound very light so it looks as if something is leaking on the fuel side must be an injector or the steel pipe going to one of the injectors will investigate and let you know what it is will be saturday when i get chance to look cheers alan

Re: renault grand espace 2.2td injectors

you will hear fuel flowing anyway as it returns excess back to the tank even if turned off you are not looking for a leak you are looking for air getting in to the pipework

Try it in the morning as this is when the air would make the difference between a good start and a bad one
