I decided to install an oil catch can just to see how much oil was going toward the intake. Did some common driving around town and some interstate driving to rack up a few miles. I noticed when I hit the gas there would be a quick fog inside the glass catch can ( Jar ) and then it would be gone. With an empty jar after driving 317 miles I accumulated 7 ounces of oil inside the catch can that did not make it inside the intake.I could never measure what was lost thru the road draft tube but that seem like a lot of oil? 1955 235 recently rebuilt and does not smoke. Good tight engine runs very well with no problems. Has anyone else with a PCV system noticed the same? | | |
