tell me the background. did you check the oil pressure manually?? what was the pressure??

if all is checked and good and no oil to lifters, you may have a bad or spun cam bearing not allowing oil to the top

Engine rebuilt about 4000 miles ago then lifters al of the sudden started chattering and I found 5 of the six on the odd side of the engine collapsed so I changed all of the lifters now they do not chatter as bad!

i think we discussed this before. either a cam bearing is installed wrong or too much rtv was used and has clogged the galley in the block
