One of the boys out here in Dubai, pinged the valves of his 1.4 K series by changing into the wrong gear. We stripped the head off the engine today and things did not look too bad, no obvious damage, however the compression on 2 of the cylinders was 70psi as opposed to the other 2 cylinders which where about about 170psi.
There is light marking on the pistons from where all the exhaust valves have touched, however there is no visible damage to the valves. Obviously the over revving has damaged the exhaust valves slightly on 2 cylinders, so here are the questions:
1: What needs to be changed, ex-valves, guides, ???
2: Is there likely to be any damage to the rods from the over-rev?
3: Is there any good sources for guides, valves, stretch bolts etc that would deliver to Dubai.
4: I am in Birmingham next week, are there any places there I could pick up parts?
Any other suggestions or comments would be appreciated
