So. Just started to change my spark plugs. First time since i bought the car. And. Well. I got a feeling this is not good? xD what should i do?

 

replace the seals

 

Is that something i could do myself? Should i pay someone?

 

takes about 10 minutes...and costs probably $10

you take the valve cover off, pull the old seals off, and stick the new ones on...no special tools required...if I remember correctly, you can do it all with a 10mm socket, and 1/4 drive ratchet...
