Sup guys. Today I was changing my spark plugs and I found a lot of oil in the 4th cylinder. Is this normal? Or did something mess up? The car still runs great.

 

I would check your valve cover seals, seems like it would be a bad seal. most of the time that will cause that to happen.

 

Will this mess anything up?

 

it will eventually mess up ur spark plug. try changing the 4 seals under the valve cver. if that dosnt solve it u will have to go to the dealership and ask for the 'rocker seals" i had the same problem and it turned out to be the rocker seals

if you do the rocker seals u will have to then do a valve adjustment because u have to losen all of the valves because the seals are under the asembly
