Hi Tom, I,ve no time to digest the valve timing today, but its usual for the inlets to open btdc and close abdc, just as is the inlets being larger dia than the exhausts.
Will go and have a look at the timing degrees before close time.
The inlets are not all open when the engine is at rest, so some "loss of timing" ( although all inlets may have been "sticky" and remained open , ie not closed by the springs ) issue caused the inlets to touch the pistons ( other way round really ) , but how did the exhausts survive ? maybe the key is missing from that cam, or bottom drive sprocket, sheared even.....have a look see...
which engine is it as there is a variable valve timing one in the data list???
