I'm working on my new to me w210 and the PO ran grease through it. After taking off the cover over the injectors I see that injector 5 and 6 are basically drowned in solidified grease. I sprayed engine degreaser and let it sit, but it doesn't look like it's working it any looser. What would work better to melt that stuff so I can suck it out; kerosene, Bio-diesel?
I'm hoping it just leaked from the braided hoses and I don't have a larger problem with the injectors themselves.
Thanks
Samson
