Hi folks - my first post!! I have had my c250 diesel estate for a few months - lovely car..should have got one many moons ago. The other day I noticed some diesel on the floor and smelt it whilst driving...got home took the plastic moulding off to inspect where it was coming from...thought it was the over-flow pipes...as all the 'wells' were flooded with diesel. Replaced all the pipes....thinking the job was done....a few hours later the same ..smell of horrible diesel in the car!! As I had left the moulding off it was easy this time. I let the engine run for a while and using a torch realised that no 1 and no 3 injectors were slowly realeasing diesel out into the wells. No problem...I thought ...quick fix...just get some injector seats from the dealer and replace!! Well, would you believe the main dealer had only four in stock!! Silly when you consider the engines are five cylinder (£1.25 surely they could keep a few in stock??) My problem is that how do I get the injectors out? I even cut a 22mm socket and welded a tube on it to get to it but no luck!! Spoke to a few mechanics...they all swear there is a tool...but none have it...and others have said they remove the rocker cover!! Removing the rocker cover is an option that I do not really want to go done as I have no oil leaks and would like to keep the engine bay that way. Can some kind soul please point me in the right direction please as I am worried that I may do damage to the engine whilst driving it as is. All help will be appreciated.
