spark plug issue

[will_s1cab]

i just got my v70 t5 and 1 spark plug keeps oiling up and then obviously the engine misfires any help with what this could be? i dont have a manual yet too look up! cheers Will

is it the plug gap thats oiling up or the ht lead where it goes over the plug.
if its on the lead its probly the rocker cover/cam cover leaking oil,
if its the plug gap oiling up it could be a number of things,
valve guides,piston rings,head gasket,cracked head etc etc.
best to take it to your local garage & let them check it out before it becomes a big issue,& a big cost

Could be PCV system dumping shed loads of oil, or the turbo oil seals.

its the plug gap the ht leads seem fine its just the one plug on the left side of the engine as u look at it

[smudgethecat]

sounds like significant engine wear has occured oiling up plugs normally indicates serious bore /ring wear

[will_s1cab]

it seems to be running ok atm like i say its just one ov them

[mexybhouy]

Sounds like valve stem or bore/ring wear in that cylinder!!
maybe do a compression test just to compare???
