Roller rocker choice for HYD rollercam/for High Miles-Full life

Nitro, Comp bloke gave you wrong info [ post #10 ]
The adjuster bolt [with cup on the end to suit a prod with a ball ] has a machined recess half way up the threads. There is a hole drilled from this recess into the centre of the adjuster, which mates with a hole drilled upwards from the cup. Then there is hole from the shaft hole into the thread area. So that takes care of the adjuster ball/cup lubrication. In the top of the rocker, there is a small hole aimed towards the valve end of the rocker, to lube the roller tip.
