NA6 oil leak

[mitch_f1]

So I have a couple of different oil leaks and I'm pretty sure I know what they are, but I just want to use the collective knowledge here to exhaust other possibilities.

It is from the passenger side of the rear of the sump, near the sump/gearbox seam. There is no oil coming from the gearbox drain, but it is moist halfway up the exhaust side of the block. I am thinking that this is the sump oil seal, as the rear main seal has been replaced within the last 2 years. Is it possible that the sump has a fracture in it?








The other leak is at the head/block join right at the back of the engine. It is just a misting of oil, not even enough to drip down. Could this feasibly be the head gasket?

Any help appreciated, thanks

CAS o ring

The oil isn't that high up the block, also its the wrong side

Still wrong side (exhaust side), and still no oil further up.

NA8 here, so I'm used to the CAS being on the exhaust side.

No worries, thanks anyway. The o-ring is being replaced anyway, just wondering if there is something I missed.
