No.4 plug hole filled with oil

[ripp]

Hi there,
Had a missfire issue recently and started the hunt with testing the coil pack, then moved to checking the plugs (turned out to be a faulty injector after all)
Anyway, glad I did checked the plugs because I found that inside number 4 cylinder plug hole there was some oil standing there at the bottom (maybe 1cm of oil in there)
On top of the whole the area is also kinda moisturized in oil coming from the VVT solenoid (if I'm not mistaking)
In the pics belllow you can see oil dripping in the hole from under the rocker cover.
Initial thought was the cover sealing has failed in that area but then wondered if somehow the oil found it's way under the cover via some of the bolts that are soaked nearby.
The vvt solenoid has a gasket as I found out, is that an easy DIY job to change? Or is it dealer time?

I reckon it could be oil leaking from the VVT seal.

Thanks for the guide mate!

It'll be from when the oil has been poured in the engine

you sure its not from where oil has been spilt when topped up? mine was soaked when I got mine from the previous owner missing the hole everytime he topped it up!

bit of both, as @Gus says.. vvt seal is a piece of piss to do anyway.

I always take care when filling with oil. Why is it such a piss to do? Looked very straight forward in gus's pics

“Piece of Piss” is a uk term for very very easy.
