First, When I pulled the plug from cylinder 2 it was covered in oil. All of the others weren't. I'm wondering is this normal.
Second, the spark plug wires for cylinder 3 and 4 seem to go in a lot further than they should, They go in further than 1 and 2. Is there something I did wrong or do I need to replace something.
Here's some pics of the wires.
