After driving it my girlfriend said it just died on her one day. I heard a chirping when she turned it over so i took the valve cover off and the camshaft is dry between the very front rocker arms and the very rear. Im not too keen on the oil galleys that lube the camshaft. do you think this is an oil pump problem or something else? i dont mind changing the oil pump just wanted your opinion. Thanks kick!
the oil pressure is checked first. if that is ok then the tiny 0.050" head gallery orifice is clogged.

or one of the cam bearings (virtual they are, just machined in the head) are bad and leak way too much, (mike them?)
the purpose of the orifice is to keep the crank and rod bearings from burning up if the cam goes bad, (hint leaks like mad from damage on cam bearing journal)
