c20xe tapping oil problem

[nova mad mave]

fitted another head to my xe over the weekend ran fine for about 100 miles then after abit of hard right foot it begain to tapp and oil light flashes on my digi dash so i cleaned all sump out and pick up were clean anyway no different so off came the rocker and i found the inlet cam oiled up nice but the exhaust cam is dry of oil ? i have removed cam and lifters and blown down all the oil ways i can see still no different any ideas cheers john

oil hole way blocked as i would say pump, but its a new pump and you only got this problem since you put on the head, and depending on how long it has been run dry it is not going to be pretty on the caps, was it sold to you and you rebuilt it or something different, id suggest you rebuild the old head and put it back on

if your oil light is flashing you must have low oil pressure or lack of oil but as said i would change the head or at least the exhaust cam and lifters

There will probably be some cr*p in the pickup in the sump
