I've got a '48 low pressure 216 in my truck. Runs fine, but I'm getting blue smoke under harder acceleration, but only when the engine is warm. At idle it's clear. When it is cool or warming up, no smoke either. I did a compression test. Results as follows: 1-111, 2-110, 3-90, 4-110, 5-107, 6-100. Not horrible, but not great either. I haven't noticed any big blow by. Wondering if it's just valve seals. Thoughts?
