read the part no. off the glow plug round connector and send an email or PM to roy (whunter).

for the black grease, its blowby mixed with soot from the EGR, to clean the intake ports - you would need to rotate the engine so the valves close and then use a rag dipped in biodiesel to mop that out, its still a dicey game but can be achieved.

I personally didnt do much aggressive cleanup in fear of dislodging some hard stuff.
