Are any of you familiar with how Ray Barton oils the valve train?

In tearing the engine down I see sprayers on the intake rockers, but not on the exhausts. Also the lifter boars are bushed and the bushings have no oil holes at all in them. Ray Barton’s people are telling me that the cam splashes enough to keep the solid lifters oiled and that the intake sprayers will splatter around enough for the exhausts.

My engine rebuilder disagrees and is going to drill an oil hole in the lifter bushings and possibly the exhaust rocker shafts as well. What do you think about Ray Barton’s oiling and what my engine rebuilder wants to do?



The holes in the bushing are done for hydraulic cams or engines that oil the valve gear with lifters/pushrods designed for through the push rod oiling ah-la Chevrolet. They are correct in that a solid lifter/solid roller would get enough oil from splash and won't need the holes.

The spray nozzle thing is interesting. Normally it's the exhaust push rods that get the spray nozzles
