leaking oil around injectors what should I do

[mudski]

You should not be getting oil coming out of your fuel injectors, only fuel if there is a leak unless you have engine problems.

Are you using much oil, are you blowing blue smoke out of the exhaust, noticed any performance issues lately?

Are you 100% sure it is coming from the injector and not somewhere else?

The ZD30 injector go through the side wall off the cylinder head and sit under the rocker cover AB. They use a special seal to stop the oil from under the rocker cover getting out where the injector is. Quite common for the seals to go hard and then leak....

With a quick google this is the best pic I can find for you. Ignore the circle in the pic. See the Injector in the pic. Its right angled. The injector goes down into the head and the short right angled arm come out at 90degrees'ish through the side of the head. This is whee they leak from.
