Hello everybody!!!

I was changing the sparkplugs on my jeep, i found a little bit of oil in the cylinder 1, all of the others cylinders were ok.:pullinghair:

There is a good reason to be worried!!!:pullinghair: Specially since the buyer already paid me.:pullinghair:

I sold it since i wanna get me another TJ, but this time the inline 6:pullinghair:

i have the 2.4l engine

when you say in the cylinder do you mean that the electrode was wet/fouled with oil? or had there been oil on the outside of it, around the body and thread? (that could have leaked there from the valve cover) post a photo if you can.

i changed the sparkplugs since my jeep run about 1 and 1/2 year with the old ones, did not feel anything bad, obviously i noticed the difference when i installed the new ones.

you made the right call, leak comes from the valve cover.
