Hi guys first time posting. I have a 2010 mn that has developed a fuel leak. The missues drives it mostly and had been saying it smelt a little fumey. So I had a look and didnt notice anything thinking not much of it. Then a week later she complained about it again this time there was a strong smell of diesel in the engine bay. After a look i noticed there was quite a bit on the engine block and what looks like around the fuel rail. I cant exactly figure it out without taking evrything apart. Interestingly this smell has only been occuring after a recent service a month ago where they replaced the rocker cover gasket. From my understanding a fair bit has to be moved to get to it. Would it be possible they didnt tighten a line properly or something?
Any insight would be appreciated. Thanks Pat
