some may be interested....

Not the first time i've stripped a head, but the pics may be usefull for others thinking of doing it, or scared to do it because they think its complicated.

The pics show the damage and cause...... the reason for me having enough and just splitting my 2.1 TB.

Good thread, shame about the damage though.

1st build - the belt slipped when the car was on there rollers bending the valves (where i think this last problem came from) (complete new top end in existing flowed coscat head)
2nd build - the block was bored off centre or incorrect HG fitted (new block, new pistons - new bottom end really)
3rd build - head noise.... they said it was solved... used it twice resulting in the above carnage.

Great Company.
