Ok so i managed to get the head off........eventually due to this happening and having to spend about 4 hours trying to get this bloody bolt out.
It was rounded off so i had to get the drill out
Then after a lot of f**king about i got it off
If you look closely you can see minimal valve-piston contact but it's not that bad.
And here we have the head obviously, it's pretty manky so i'll pull it all apart and see what's what
Just got as far as getting the exhaust manifold off before the missus arrived home with a chinese takeaway, so that was that, as you can see i took the manifold off and it's cracked inside, there's about a 6 inch hailrline crack you can just see the start of it in this pic.
So that's it so far, long way to go yet.
