just collected it and drove it about 200 miles home
its my first v6 alfa
having played with juniors, alfetta gt, gtv
but it has a knock
sounds like its coming from the heads
loud at start up and softer once the engine has warmed up
engine has 171000 miles, but there is no smoke and plenty of power
so i am presuming there has been a recient rebuild
i removed the front (left) tappet / valve cover
gasket looks to be only a few months old
valves have been set on the tight side
sticker on radiator says .5 for intake and .25 for exhaust
and both are less than that
please advise what you think it could be
and how i can go about eliminating possible causes
thanks
