Sudden oil loss down passenger side Block (m103)

[ps2cho]

I have trying to track down my oil leak on my 300TE and I put some UV dye in yesterday. Checked tonight and it is leaking down the left side of the block at the back. It is NOT coming from the valve cover and is not coming from the driver side of the block.

I can't "quite" see where because the exhaust manifold blocks my UV light...but I cannot believe the head gasket could be leaking. It hasn't even been 10k miles since I replaced it last year. Car has never overheated. It all started about 1k miles ago. I had the head skimmed and pressure tested and followed the torque procedure with the 2x 90deg turns +- 5deg.

Is there a chance there is some sort of oil plug on that side of the block? I won't be able to jack it up it for a few days, so wanted to get some ideas on where it could be coming from?

It is losing enough that I am "smoking" on the freeway in the morning quite a lot.

Thanks
