Valve dent in my 300TDI piston!

With nothing much else to do in the snow, I took the my 300TDI dicovery engine apart. I have a new cylinder head to put on, so I dropped the sump off and took the pistons out as well… might as well replace the big end bearings and piston rings whilst I'm doing the head. There is some good wear on the bearings as you'd expect as they were in from new and had covered 130K miles. The only thing of note was that the piston from the number 1 cylinder had what looks like a valve mark in it.

So, I've a cylinder head from ebay in the hope that it's ok, new big end bearings and in the end new pistons (as it was only a few quid cheaper to buy them built into the cylinder.

When it warms up I'll try and put it back together…
