Rebuilding a cylinder head for a 1918 Buick, 4-cyl.
This engine has external rocker arms and springs.
Using new stainless valves and bronze guides, what would be a safe valve guide clearance to run. I’m leaning towards .002”, but would like to get more feedback. No oil supply to the external springs, rockers, but there are oil ports on the rockers.
What would be the proper procedure for driving this car. Do we manually oil the rockers at the start, and at some predetermined mileage, not sure.
very interesting project so far.
