Stripping Spark Plug Threads

Featured Replies

What do you do for stuck plug wires? The subaru dealer who changed the plugs last obviously didn't use dielectric goop so the wires are seized to the plugs. Looks like I may have to cut them out.

 

At the wires I did get out, I found at least a teaspoon worth of engine oil around the outer portion of the spark plug tube. Is that somewhat acceptable?

 

Your spark plug tube seal(s) are leaking. The solution is to replace them along with the valve cover gaskets since you have to remove the valve covers to replace the tube seals. It's not hard at all to do. I recently did this on my '02 Legacy and it was pretty straight forward. I bought the entire valve cover/spark plug tube seal/grommets set made by Felpro from Advance Auto Parts for about $25.
