The last 2 mornings my ml w163 2002 model failed to start. When I turn the ignition key it turns the engine over but it doesn't start. After about 10 minutes of trying it starts. Is this a sign it needs new glow plugs???
yep fully agree, tony jr has given the full and final answer.
Hopefully its just the o-rings as seen by bubbles in the clear lines, they are cheap and easy to replace.
I'm interested tony, do you have a link or something for replacing the injector HP seals in-situ? I have one injector that is leaking off more than the others. I was thinking I would have to get a whole new injector, but if it can be DIY that would be awesome.
I have two injectoirs with excessive leak-off. I rang around a few garages and they said I needed to replace the injectors. I was loathed to do this because of the problems I had had previously experienced trying to remove a stuck injector that took over 10 hours so a spoke to diesel specialist on another forum who told me that on commercial engines diesel fitters often just replace the seals with the injectors still in the engine. I spoke to a local injector specialist and he said he does this alot and he did both of mine in an hour and half and charged me £100 + vat - the engine fired first turn of the key!

tony_jr,
Who did this for you as I need a couple doing and not far from Nottinghamshire ?

How does that stop the copper seal at injector face leaking though? People struggle to remove injectors because they dont have the correct tools/knowledge. I have never failed to remove an injector from any engine under any circumstances.
I know what you were talking about with the high leak off......
Point is, high leak off or not, the injector is stuck for a reason, probably the black death has already started and not worked its way up to the rocker cover yet.
So even though someone has replaced the seals in situ, its still only half a job in my opinion as not resealing them is just another issue to fix when they are even more gummed up.
If you remove them with a hot engine using the correct puller/slide hammer, even the most stubborn ones will come out, in less than 7 hours too!!
