In addition to the classic oil cooler area, the hex plugs on the front of my TDV8 diesel engine head appear to be weeping oil.

I've done a long www search, but can find no detail on these and what seals they use? Has anyone had this problem and solved it?

I'm guessing they might be sealed with viton type O rings, but do any of our experts know the size / spec / torque settings on tightening etc?

Many thanks in advance. matt

Pictures please.

Thanks Mike. There appear to be at least two leaking.

There is one at the front of the top, left (as you look at the engine from the front) head of the engine, as photographed. Top photo taken a bit upside down / from the side so you can see more 'into' the plug. My out-of-focus finger on the left pointing at it.

Second photo is taken further back and looking down on the leak: the weeping plug is just visible behind the hose connector in the centre of the picture.

The second (which looks a similar size etc) is much lower in the engine - at the front and mid-way but too low down to picture at the moment with bits in the way. I think Nino may have previously identified this as a potential leaker?
