Hi all, I have a week in February where I won't need the car so in addition to upgrade headlights/oil/filter air filter change I would like to change some of the glowplugs if possible. Car always starts (even at -5) so I don't want to take apart inlet manifold etc but according to the internet there are 4 of 6 that can be changed without removing anything so I'd like to just change those - might make the starts smoother as currently it judders/splutters into life with a bit of white smoke when ambient temperature less than 10 degrees, doing 2 or 3 ignition cycles helps reduce smoke/start better so assume glowplugs are not all good.
Has anyone done this without removing the manifold and is there any specific tool that can be recommended. Is it possible they could break when removed so best left alone or with penetrating fluid will they be OK? Not sure when they were removed although head was reskimmed and valve seals done 2 years ago so would they have removed them then so they should be OK or would they have just left them in while doing all that?
While I'm at it main fuel filter is 3 years/60k miles old, does that need replacing too?
Appreciate the advice here as always, Ben
