Reply To: '54 Merc Rocker Arm External Oiler kit

[John & Shirley Harvey]

I have never heard of one of these kits for the Y block. The most common problem I know of with the Y block is the rear main seal. Falcon 144 CI 6 cyl engines suffered from an overhead valve oiling problem, and the external oil system was real common with them. That problem was cured with the 170.
