All seemed dry and felt dry, but I thought best fix it whilst I remember.

I removed the lid, reseated the O ring, started the engine and no more leakage - I'm just stumped as to how that much oil could be leaking out, without it being obvious it was from the oil filter cover?

More checks to make, to be sure it is fixed, but looks promising.





That's good news. It doesn't take much to nip the o ring. I think it is something like 22nm torque.

Check for the pcv in any case, as if it was blocked and pressure built up, that would be the weak point for it to leak from with pressure.
