I'm putting an Offenhauser valve cover on the 223 in my '62 F100. When I knocked the freeze plug out to install a road draft tube I discovered that the block, casting # C1AE-6015-K, is not drilled and tapped for the draft tube mounting bolt. I really don't care to drill and baffle the cover for a PCV valve so I've got 2 ideas,
1. the tube mounting flange is a slight interference fit into the hole so maybe a high temp sealant would work. The tube has a support bracket that is held in place by an oil pan bolt that would help keep it rigid.
2. drill a freeze plug to accept a PCV valve.
I'm looking for opinions if either of these would work or better ideas . Thanks, Dave.
