Hi all decided to change spark plugs in the 2.5 V6 Omega today to find that on two of the passenger side plug wells (not the middle one) there was oil in them, not too much in the front one but quite a bit in the back one - what's your thoughts? - drivers side clean as a whistle.

Hi,

More than likely your cam cover gaskets are leaking/breathers blocked

Cheers,
Iain

Failed cam cover gasket

I changed oil about a fortnight ago so oil is nice and clean although oil in plug wells is dirty.
Is there any way of checking if breathers are blocked - someone suggested if oil is spitting from dipstick that is an indicator.

best way is to remove breather pipes and look at crankcase breather box / see if pipes blocked. then check breather channels through plenum cover. worth checking/cleaning these every 18 months to prevent cam cover leak and oil in spark wells... when was the last time your breathers were cleaned? if more than a couple of years you should clean them as a matter of course

Read the section on cleaning breather system in the maintenance section and when you replace the camcover gaskets use only genuine parts as cheap pattern parts don't last long .
