Thanks everyone for your help. I haven't been able to find time to get back on here and respond.

But, I did change out the CCV's and they actually didn't look bad. What I did notice (after further inspection) was that the valve covers themselves seemed dirty to me (where the CCVs clip on). I'm guessing I'll have to take the covers off to clean them out? I know I'll have to get a new gasket (I think they sell a whole set) for both sides but is there anything else I would need? I'm guessing this would be a pretty complex DIY? Has anyone done this?

Also, my service engine soon light came on a few days ago (before I changed out the CCVs - but haven't driven it since). I'm guessing it has something to do with the emissions, because it still smokes out the exhaust?


EDIT: I also didn't use any seafoam. I didn't want to risk it.
