      Little bit of Oil on Spark plugs

      Hi guys. The other day I changed my spark plugs and wires. When I removed the plugs number 3 and 4 I noticed there was a little bit of oil on them. It was not much but it was there. How can I know what the cause is. My first guess would be the valve cover gasket, but as I understand it, there can be a few issues that cause this.

      Any ideas?

      Thanks!

      The ONLY place that can put oil on the porcelain of the spark plug is a bad valve cover gasket unless the valve cover itself has holes in it.

      Ok, I get it. Im not sure if the porcelain itself has oil. I changed the spark plugs about 2,000 miles ago, and the old ones had a ton of oil, I cant say if the oil was in the porcelain or not. Im gonna add some pictures, maybe you can tell me something about the engine by looking at them.

      Heres a gallery: https://postimg.cc/gallery/Cbj0qN0

      I have named all of the pictures so that you know what each one represents.

      Based on this, do you think I have a bad gasket? Or maybe something else that you can tell me from those plugs?

      Thanks in advance!

      If there was any oil in the wells where the spark plugs go BEFORE you pulled them out, you have a bad valve cover gasket. Judging by the "old" plug pictures, you had oil in the spark plug wells.

      Replace your valve cover gasket

      Well, woke up, saw your message, went to the parts store and bought a new one. Also took some pictures, the wells looked clean, but changed it anyways just to be sure, I had already bought it. Here are the pictures: https://postimg.cc/gallery/Wb61YYn

      Thanks a lot!!
