We extend to you a cordial "WELCOME ABOARD !" Come on in, make yourself at home, we are a friendly group of enthusiasts, and we also appreciate the classic Chris Craft Roamer, Corsair, and Lancer boats too , as they are all on the same family tree and share much in common !
I'd like to hear some thoughts from the mechanics on this one.
I've posted previously regarding the revitalization of the 427's in my 1973 36' sportfisher. I'm pleased to report that they are running beautifully. The cameraphone photo below shows an aft view at around 3200 rpm / 22mph. (notice the progress on the toe rail)
After running at speed for a few moments, I opened the floor to check for anything unusual. What I found was an oily mist coming from the breather on the oil fill cap of the starboard motor. This cap has some filter material in it, but the mist still flowed out. It wasn't smoke. I had added >.5 quarts of oil to that motor before leaving the dock because the level was just above the bottom end of the range on the dipstick. Compression on the engine is great. All cylinders are within 15lbs of each other and are greater than 175lbs each. I would think that makes blow-by unlikely. There is abnormal no odor to the exhaust (like the distinct smell of oil). Is this as simple as a failure of the filter material in the breather? Should I be concerned? The other side breathes into the flame arrestor.
