Oil on spark plug

[Timbo267]

Hey all,

Went to service my ph2 172 on the weekend and found oil as I pulled out one of the plugs. Anyone had this before and any idea what it could be? Cheers

I would clean up the rocker cover and try to determine where it’s leaking from, its covered quite a bit of it now.

My initial thought is that it’s the dephaser solenoid seal, but a clean up first should help you track it down.

Thanks mate

Could be the cam cover leaking as well. If it is, it’s a cambelt job as the cover is integral for holding the cams in place.

Such a c**ty design

Yeah not ideal. A favourite of mine is when people reseal them with about 10 foot of rtv and then wonder why it’s clogging oil ways up. 😂

Spark plug seals, that sit in the rocker cover maybe.

Cheers guys. I will get the cam cover off and check it out

dont remove the cam cover if you haven't got the timing tools

Which plug is this? Is it the one next to the filler? If so my first thought is that someone got a bit exited and spilled some oil down the hole... nothing to worry about.

My first thought. In the background of the pic there's a big old oil trail starting from the filler cap.

No it is the 3rd one from the filler

No oil in any others apart from the 3rd. I wish it was that simple lol

Unlucky! Looks like the plug hole filled with oil as your socket was covered too - so maybe the rocker cover as mentioned above.

How long till your next timing belt is due? Might as well get two birds with one stone. Maybe it can wait if the belt is due soon and it's not leaking much.

Definitely the rocker cover then.

I am just going to do it all together for piece of mind, it concerned me with the amount of oil in there so it is all coming off for a proper look.
