Oil in Prechamber

Last night I pulled my injectors and was supprised to find a pretty sizable amount of oil in the prechamber/injector holes, if that makes any sense. I did a search on this topic and this is what I came up with.

Oil in 2nd prechamber.

Is this some kind of serious problem? Can I clean it out with WD-40 sprayed into the prechamber. Thanks for your help.

It is something which can be serious....
So I suggest you keep looking for where it has been talked about...
I think it can cause the precombustion chamber to burn out...
I was not able to visualize the path that was talked about... but I have seen it in the shop manual also....

Head gasket or drippy injector is usual cause. You can clean all you want but it isn't going to fix the problem. Having the injectors checked is pretty easy: take to injector shop, have them show you that they have the manual for your injectors, then insist on numbers for crack and spray - before and after adjustment - as well as visual check on spray pattern.
