Spark plugs fouled BADLY!!! HELP!!
Hello Board, I have a 1987 300E, I pulled the spark plugs today and # 1,2,3,6 were covered with a hard crusty build up. I think have 2 problems:
1. My car is running rich, It could be "carbon bulid up"??. I've posted this a few times,.
2. My car's oil is too thin(I live in Miami,FL and I run 10w-30) and is leaking past my valve stem seals. I think that I will have to switch to 20w-50. I noticed a little oil on the threads of the spark plugs.
What could that hard crusty build up on my spark plugs be??
Oil or running rich OR BOTH??
HELP!!
