rHello all, I am in the same situation, with no oil in the rocker arms, found out that the gasket was upside down, since my mechanic repaired the block, and the unit was being used, like that, after a sertain period of time, a noise started to come out of the head cover, so, we put a new gasket, correctly, checked the rocker arms train, all looked ok, only the 4th rocker was hard to be moved up and down, so we disassembled all the rocker arms from the train tube, all looks good now, but now, with the gasket in the correct position, oil still does not want to up up to the rockers small breathers, nor to the set screw that is on one side of the rocker arm train, while engine running, oil doesn't go up, so we took the distributor off, put an old one without the gears that insert inside the block and using a cordless drill, we spun the pump, but still no oil came out at the rocker arm train, so I cranked the engine a few times, then oil started to come out, to all the rockers orifices, and taking off the set srew which is by the end of the train, oil came gushing out really nice, but after re cranking the engine again, oil stopped coming out, some say pump is bad, which I don't believe, others say might have been heated up the block and the camshaft and metals are the problem, any advice, I still don't want to take engine off, before getting another advice.
