Misfire and oily bits - Saturday morning crisis

Missus home last night with a misfire. Codes say cylinder 2 and I’m up this morning after a google and about to swap coils over, but after running the engine for a bit I noticed this?

An arsehead of a mechanic did an oil change a few weeks ago, and there appears to be pooling oil. I believe this is the housing for the filter - in this is mechanic (MY mechanic!) job now?

Thanks 2.5 M54 90k

Just to add that was after running for a few minutes to read all the codes again before I started on coils.
 
That is the oil filter. He's either not tightened it down enough, nipped the big O ring inside or forgotten to put in in at all (filters come with a new one)! You need a big socket to fit the top, anything else may damage the plastic.
 
Ah, okay thanks - only got a plumbers spanner big enough so maybe a garage job.

Especially as swapping 1 & 2 just made them both misfire and I’ve noticed this around number 6…which I’m sure isn’t where oil is meant to be.

And number 6 doesn’t look well at all.

Abandon.

You sometimes get oil in the sparkplug holes if the gaskets between the holes and the rocker cover fail or if someone hasn't taken care when refilling the oil. Oil in the ignition coils will make it misfire.
 
Thanks, I’ve shone a torch and there is drips of oil in all the spark plug holes so looks like a rocket gasket then. Not too horrendous! Swapping and reseating the coils just make more misfire codes - oops.

Breakdown coming out to investigate the oily filter housing as it’s really flooding out - and if that’s sorted I can limp to the garage next week. Thanks for your help.
 
Oh my goodness, I would have thought it was worth getting the right sized socket on Amazon just to have a go at the oil filter housing yourself. Have you even checked its hand tight? You are in to £00s as soon as it goes anywhere near a mechanic.
 
Well I went and bought the 36mm bit (and an adapter for the torque wrench), a new Mann filter and swapped everything over - and although the filter in there already was new, the or ring was flat/flush which is why oil was flooding out. The new one in the Mann kit was round and was snug. And voila, no more oil leak.

And then I managed to play clear the code/swap the coil and fixed the misfire too by getting a new bosh coil from ecp. Feeling pretty chuffed!
