    Just rebuilt this engine crank grind new shells new oil pump/ piston rings. cyl/head decoke etc.
    run mint for a few days now tappets noisey,on investigation lack of oil to tappets.oil pressure good on cranking and when running. On this the oil comes up by the side of the head bolt through gallery into head, removed the bolt and oil is present blown out oil ways rodded where possible.Does anyone know is there a valve or anything I might be missing, i have fitted new tappets as i thought i had enough oil coming up to the cam there are no marks on cam or caps, on starting it seemed to quiet down, so i fitted rad back on run engine to warm, but tappets went noisey again, on removal they have'nt hydrauliced up.As anyone any ideas.
    thanks john.
