So inside crank seal was a ring as seen. I am just wondering how it is sealed to crank or sprocket. Engine oil can flow between crank and this ring so is somewhere a missing gasget or do I have to put sealant somewhere?

And

[Andy B]

the outer diameter is sealed via the front crank lip seal .... the bore/inside diameter is sealed via the crank pulley being tight against the front face of the ring. You might want/need to turn it round so that the crank seal has a new bit of the ring to seal against it. no sealant required.

Thanks Andy B, I was afraid I'd lost spmething. Good idea to turn it. It is badly worn. I tyrn it if I can polish the other end, seem to be corroded. Perhaps I can find a spare, quite strange contruction.
Torque value for crank bolt was not mentioned in V6 list of maintenance part. Any idea. I have Heynes somewhere but did not find it yet.

It should clean up OK with some fine emery cloth

No idea I'm afraid, just know they're tight.

Crankshaft Sprocket Bolt according to Haynes manual:

Stage 1:  250 Nm
Stage 2:  Angle tighten a further 45 degrees
Stage 3:  Angle tighten a further 15 degrees

I have a link to the manual so I’ll try to send it to you so that you can check it for yourself.
