Whats going on here then...

I only have basic knowledge. Noticed this a while back, thought I'd better do something about it but know nothing.



I guess the small rubber pipes are some sort of fuel return because the liquid leaking on them is diesel. I can't find a split on them, I guess they are just a poor fit and the diesel is running along them. Bit concerned about that black leaky patch though. Can't really see where it's coming from. Guessing the head gasket is gone?

All help appreciated.

HG hasn't gone - i'd be changing the injector sealing washer - the leak offs and the O ring that seals the rocker cover to sump return cleaner (that cylindrical black thing)

also check the braided hose connected to it is tight

once you've done that clean it and check for leaks after a ickle drive

and treat yourself to a new rocker cover gasket
