i have a 1992 accord ex. I have oil in the spark plug wells so am replacing those and valve cover gasket.
I have a couple questions.
When i have the valve cover off is there anything else i should while i have cover off like check valve clearance, etc?

2nd question
What exactly should i replace if oil is in spark plug well?

3rd question
Do i need to replace spark plug wires or can i just clean the oil from them?

 

check the sticky FAQ's at the top of this forum for "spark plug tube seal replacement"

You will need to remove the rocker arm assembly..which can be a pain for a first timer but just be patient. You can choose to do a valve adjustment at the same time but it's not completely necessary.

There are two sets of seals you will need to replace..the spark plug tube seals and the upper spark plug gaskets. They sell a kit that includes the valve cover gasket as well. Just check rock auto and ebay.

It will be up to you to replace the spark plug wires. If they are old, I would replace them but it's not completely necessary unless the end grommets come off when you remove them which can happen after repeated exposure to oil.
