Just had a text from Liam who's read this post put said he'll post up later, he said........
I dont think the valves are damaged tbh, i put oil in the bores b4 left so i'll see what happens tomorrow.
Also if he thinks that the bores can't be damaged, how does he explain the crank case smelling of fuel?
If he wants me to show him the bores, he can come down to my garage and i'll show him.
I think we'll have to wait and see until tomorrow now......
