I have a 2006 EVO 9 at around 63K.

I replaced my spark plugs. There are a thin film of oil around the metal part.

Do those old spark plugs look healthy?

Facing the front of the car.

Thanks!

 

When in doubt change them. They're cheap.

 

I replaced the 4 spark plugs already.

There are oil on the threads of the 4 old spark plugs.

I might need to replace 4 Spark Plug Ring Gaskets and Valve Cover Gasket.

 

Some people replace plugs when they do oil changes. Easy to get to and pop out. What do you gap them to?

 

Yes, seems like it. I would replace the valve cover and ring gaskets and monitor.

 

When there's oil on the threads, it comes up from the cylinder and stops at the washer.

If it was coming from the valve cover, the top end of the plug would be swimming in oil and it's not.

It's not going to fix anything, the new ones will look the same in no time.
