today i have remove the head manifolds and the valve, the problem valve is and exhaust valve which has eaten the valve guide made it oval,before i removed the valve i had the car running and had a look at the hole to see if there was oil comming out which there was a constant dribbile equal from each one,i had emagined that there should be a small spray from these and not a dribble,i have also checked the conrods oil hole and the oil hole is facing the valves also the piston cut out lined up with the cylinder bore holes.
question the cylinder holes should they spray or dribble,
my assumption which is the valves were dry,valve guides which were new may be too tight when warm not reemed out maybe causing the valve to seize.
tommorrow im taking all the valves and checking and fitting a new valves guides where ever needed,luckly i have spare valves and guides,
has anyone had this problem before!!
cheers dave
